Hey indrek ı am using Arduino UNO with 12Mhz crystal but i am having some problems ı can only run lowest resolution and two duplicate half Frame in your plugin monitor
The image window is opening up, I assigned the correct port and baud rate, but it is not rendering the red rectangle. What could be the issue(I am using Arduino Nano)
Hey! Did you set "#define EXAMPLE 3" in "setup.h"? Did you try with a plain Arduino without any additional wires beside the USB cable? The red rectangle is sent after boot-up, and sometimes the Java program can miss the frame. Try to press the reset button on the Arduino then the image will be sent again. If that doesn't help try with a lower baudrate. In the "ExampleUart.cpp"set #define UART_MODE 4 Now you have to also select 115200 in the Java program.
@@IndrekL i have same problem man ! i downloaded 1.8.191 jdk and i did all you done but doesnt work. i tried to change mode 4. but image window is opening up and didnt show red rectangle. can you help me how can i solve ?
Hi, could you please share the wiring details for the Arduino Mega? I'm still getting a red screen, and I suspect that the wiring is incorrect. I'm working on integrating the OV7670 camera module to stream images to a computer and then uploading a machine learning model to analyze the images.
I changed your java application reads bytes from bluetooth but it shows only a small top part off image how can read images from bluetooth can you help me please if you can i will be very happy
Congratulation for the project. Is it possible to use RBG and 640x480 or more resolution to PC screen?, i try with default setting, only works 160x120 RGB with 115200 baud for me, i need more resolution.
eror code IDE : In file included from Adafruit_ST7735_mod.cpp:24:0: Adafruit_ST7735_mod.h:34:26: fatal error: Adafruit_GFX.h: No such file or directory #include ^ compilation terminated. Error compiling. what happening about this ?
Hey! You have to copy the "Adafruit_GFX_Library" and "LiveOV7670Library" from "src/lib" to your arduino "libraries" folder. C:\Users\\Documents\Arduino\libraries
i applied all steps but i see only green image on java application i dont know where im wrong all wirings are right, i checked them many times but when i run java application there is only green screen what must i do please help me :(
Green means that the camera is running at Arduino was able to configure the camera. Do you have any way to use an Oscilloscope? It would be good if you could check if VSYNC and Pixel Clock signals are working.
@@IndrekL you are right l have checked lt yesterday with a multimeter vsync has 0.30 volt heighest value and the lowest 0.05 volt and the code stucks at waitforvsync , what must l do whats your advice
Multimeter is probably too slow to detect the pulse since the pulse is very short. Maybe try to replace the VSYNC and Pixel clock wires. Perhaps there is a bad connection somewhere. Or the wire is broken.
Hi, your videos were very hepful. I've followed your tutorial step by step. I had the red screen initially and then the Green screen at the mid-test. But whenever I connect the remaining pins, I also get a red screen. Am I doing something wrong? Also, I have an Arduino clone, but it has an DIP atmega328P, so apparently it doesn't support 1M baud. Is it possible to reduce framerate so I can use smaller baud rates with a bigger resolution? I'm trying to setup a camera to capture a Gray scale frame every 10 seconds and send it wirelessly via LoRa and then store on a PC. But so far I'm stuck at the camera setup, can you give me any hints?
Hey! If you get green screen and then red screen after connecting the rest of the wires then there must be something wrong with the rest of the connections that causes the camera to stop working. Maybe you can connect the rest of the wires one-by-one to see at which point it stops working. Yes, if you play with the resolution and frame-rate you can get also higher resolution with slower frame rate. What resolution and baudrate do you want? I can make the configuration and add it to the pre-set options in the "ExampleUart.cpp"
@@IndrekL Thanks for the reply!! :D The day after I wrote that commentary I was able to get some footage from the camera. I think the issue I had was due to using old jumpers, but I've already ordered a new pack of those as replacement. So far in my project, I've managed to transmit data serially (software serial) at 9600 baud through the LoRa module I'm using to another module which receives the data and send it through an Arduino to a PC. (Theoretically the module can link at 115200 baud but I'm having issues changing it's default settings). It's a low-power project where the camera is triggered by a motion sensor, like those in bathroom lights. So in my case I won't be needing constant "live" feed but rather a single frame whenever someones passes by and triggers the sensor. The sensor takes around 8.6 seconds to warm up after each detection, which is the theorical shortest delay I'll need. So I guess any baud rate would do fine for me as long as I can send a compressed VGA image in less than 9 or 10 seconds. This motion detection bit is also already complete. I've already tampered a little with your code and managed to get a feed on grayscale and VGA. But I'm not sure If I've configured It properly. I think I won't be needing colors, but as much resolution and as low Blur as I can get, since my end goal is to use those captured and transmitted images on a facial recognition software or, at least, on a human detection software I'll build in python. (By the way, all the images I've got we're a lot blurrier than what you've shown at the end of the video. Is that just lens adjustment or It has some software settings involved?) It would be great If you could help me out with the camera settings and clarify a little of what you've done in your code, so I can make a similar one that triggers with an Arduino output and sends the frame through SoftwareSerial(). (Sorry for the long text, I felt It would be easier to explain by giving some context of what I'm doing)
@@VitorJTekkRodrigues In this case you actually should use the FIFO version of the camera. If you use my code with slow frame rate and you want to capture a moving object (a person walking in front of the camera) then the image will be very blurry. FIFO version of the camera can take a snap-shot very quickly and then you have time to send it over the slow serial line.
@@IndrekL If It manage to set up my radio module to operate at 115200 baud, would I be able to still use the non-fifo module? Because I don't have a FIFO version and it's probably going to take a month to get It if I order one right now, and being a college project to be delivered at the end of August, I'm probably stuck with what I have right now.
@@VitorJTekkRodrigues If you want to capture moving object it will be distorted. Like here when the camera is moving 0:14 Fifo version will quickly capture the image into FIFO buffer and you have time to send it over the slow connection
Greetings Sir; I would like to ask, after capturing the objects... I would like to save it to another folder for data file storge. How can i do it? Thank you for the kind respond.
Hey! I have a question. I did a PCB with this and everything was working fine, and I was watcing the streaming in the Java screen. But then, I plugged another arduino to see some data in the COM of the new arduino and the Arducam stopped sending images. And now, I plug the arduino nando with the arducam and it does not connect, it aways appears a red rectangle. Any suggestion?
Hey! Can you still upload the code into the Arduino that is connected to the camera? If uploading code works then sending image from Arduino to your computer should also work.
@@IndrekL It is still uploading the code from Arduino IDLE. It is kind of strange due to it worked just but when I attached other arduino with its own COM it stopped worked. Sometimes it works and some times it doesnt :/
Maybe the problem is with the rxtx library that the Java project is currently using. It is old and not developed anymore. I should update the Java project to this instead: fazecast.github.io/jSerialComm/ This would probably solve the issue.

The image format is not correct for the Java program. Did you download latest version of both the Java code and Arduino code? If yes then check if you selected correct baudrate in the Java program. By default it should be 1000000. If that is still correct then try lowering the baudrate by changing the UART_MODE in ExampleUart.cpp and then select the same baudrate in the Java program.

Hey! Yes transferring data to the EXP8266 module and then over wifi should be possible. I haven't tried it myself tho. The ESP8266 has too little IO pins to connect the OV7670 (without FIFO) directly to the module.

Hello , i am wondering if you can help me with a problem. I made the wiring and the program , the frame on java is starting but the problem is that nothing appear on the frame , not green or red display , nothing . If you know anything about this , let me know . Thank you ^^
Hey! You should get the red image before connecting any wires to the Arduino. Try to load the code into an Arduino that doesn't have any wires connected (you have set the #define EXAMPLE 3 in setup.h). Then open the Java application and select the same comp port number that you used in the Arduino IDE to load the program. Then you should get the red image. After you have successfully received the red image then we at least know that the connection between the camera and your computer is working. Then we can continue with the next step.

Can I ask you about how I should be save image from form to my local computer? And could be I compile this project like executable file for run on any computer?
I will add saving option to the java program soon. I have been asked about that a couple of times already but I haven't had time to do it yet. I haven't done it myself, but it is possible to create self contained executable for java application. Here is one StackOveflow question about it: stackoverflow.com/questions/2011664/compiling-a-java-program-into-an-executable
I did some googling and it is quite simple to use IntelliJ to compile the project into a .jar file that can be run by double clicking on it if you have Java installed (you also have to copy your platform specific rxtxSerial.dll next to the .jar file - for me it was win64). If you want I can write more detailed instructions how to do that. I haven't tried this myself but now it should be possible to use JSmooth to create an exe wrapper to the .jar file.

If you see red then you most likely have the latest version. Red screen means that sending configuration failed. There is either problem with XCLK signal or the i2c connection. Do you have an Oscilloscope? If you have then you should check XCLK on the camera side. There should be 8Mhz signal on it. If this is OK then you should try to check if camera is sending out PCLK and VSYNC signals.

@@IndrekL In function "initializeScreenAndCamera()" interrupts are disable(noInterrupts). Is it necessary? I'm going to send bytes to PC only in certain cases. Can I enable interrupt while I don't send bytes?
Yes, you can enable interrupts while you do not need to read image from the camera. Reading pixels data from the camera is very time-critical and any interrupt that is triggered during that time will break the image. By default there is only timer interrupt for "millis" that breaks the image. I call "noInterrupts" to stop that. Actually to disable "millis" interrupt setting "TIMSK0 = 0;" is enough. But if you add your own interrupts you should disable them also while reading image ("noInterrupts" will disable all interrupts). Do you want to use an interrupt for the "save image" button? Wouldn't it be much easier to just do "digitalRead" in a loop?
@@IndrekL Of course I will use "digitalRead") I'm going to connect one more module to Arduino and maybe I will need interrupts. But maybe not, I still think about it. Anyway thanks for the help) If I have any more questions, I will write.

I think it should be possible. You have to find a transmitter that could transfer data at least 1Mbit/sec. Otherwise, it will be very slow. I haven't had time to do it myself yet, but at some point in the future, I will try it.

@@dondixon4206 Yes, you can select a folder in the Java application and then all the images will be stored into that folder. Maybe you actually need the FIFO version of the camera? Arduino doesn't have enough memory to hold a frame. So it reads the image from the sensor and then immediately sends it out from the serial port. If the serial connection is slow then the image will have to terrible rolling shutter effect. The FIFO version of the camera can take a snapshot and then there is time to send it slowly over the serial connection.

The basic idea for the wiring for Mega is the same as with UNO. You can follow the Uno video, but make connections as described here at the end of the page: github.com/indrekluuk/LiveOV7670#connections-for-arduino-mega
Hey Indrek, Thanks for the video, i'm getting a clear green and red screen, however when i try to capture the camera it's shows me a gray glitch screen. Do you know what the problem could be?
It seems to me that the clock signals might be noisy. If you have an Oscilloscope then you could take a look what the signals look like. But maybe try to solder the XCLK and Pixel Clock wires instead of using a breadboard.
Hey! 10k is common practice for i2c pull-up resistors. The camera module's input signal must be below 3.3V, but Arduino output is 5V. So when I build a voltage divider with 680 ohm and 1k resistors then the output will be about 3V, which is good enough for the camera. It probably will also work with two 1k resistors or two 680 ohm resistors (or any resistor in that range) - then the output would be about 2.5V The total resistance shouldn't be too high since then the signal starts to deform. If it is too low it will consume too much power (Ohm's law). With 1680 ohm total the signal pins voltage divider will consume 5V/1680ohm = ~3mA, which is low enough.

Are you using an original genuine Arduino? For some reason 1000000 baudrate does not work properly with genuine Arduino. You have to lower the baudrate (which also makes the image much slower).

Hey! If you try with an Arduino WITHOUT any wires (just a plain Arduino connected to you computer). Do you get a clean red square? If you can see clean red image then we can be sure that the Arduino to PC side is working.
Hmm up to 3:40 now, after I click listen, the window closes and this error pops up # A fatal error has been detected by the Java Runtime Environment: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000180005156, pid=4732, tid=15232 any idea why?

What version of Java are you using? Probably the rxtx library I am using for the serial communication does not support newer java versions. Please try java 1.8.
@@IndrekL Okay now it doesn't close the pop up window! But different problem instead rip, no red squares appear when I press listen, and when I try to press anything in the window like change COM or Baud rate it spams this to me: Unknown command code '0' Unknown command code '0' Unknown command code '0 What might be the problem this time?

@@SupremeNoble The "Unknown command code" will show if correct baudrate is not selected. Did you try with just Arduino (without any wires)? And select the same com port number you used for uploading the sketch to the Arduino. Did you use the default 1Mbit baudrate?
@@IndrekL hey yeah, I used 1M which was the problem as I realised I was given a genuine arduino board rip. Got the small 115200 red square to appear :D And right now I just got it to work! Kinda sad the genuine arduino board doesn't allow for bigger image resolution but thanks for the tutorial man!
Can i send the captured image to a zigbee device and transmit it to another PC? I'm getting a frequent error saying , Process finished with exit code -1073740777 (0xC0000417). and the java window closes with the above error displaying in the terminal. Any suggestions on what to do ?
Yes if the zigbee device can receive bytes from serial port. It seems that the rxtx library crashes. Does it work for a while and then crash or it doesn't work at all? Did you receive at least green or red screen from Arduino?
@@darklight8235 This is strange. It seems that you receive something and then it crashes. Are you using Windows or Mac? If Windows is it 64bit or 32bit Windows? What transmission speed did you select?
What version of Java did you use. I did it with Java 1.8. Did you try Java 1.9 or newer? Did you also download 64 bit Java? Maybe just try to use win32 library path instead of win64. This is strange I didn't have any crashes.

Try with slower baud rate. I assume you already set in setup.h #define EXAMPLE 3 Now in ExampleUart.cpp set #define UART_MODE 4 (by default it is #define UART_MODE 2) and re-upload the code to Arduino This sets the communication speed to 115200. Now when connecting select in the java program "115200"
You probably didn't select correct folder for JDK. Did the folder look something like this? C:\Program Files\Java\jdk1.8.0_131 NB! it has to be "jdk" and not "jre"
Very good job and demonstrating the problem with the slow refresh of the next frame. In my opinion it doesn't worth implementing it in a project and I'm thinking of throwing it. Maybe it's good for taking a picture and that's it. Yes it can be useful for this application and it takes a colorful picture which is nice. I don't know what application I might use it to take pictures for something.

I haven't had time to do it myself yet. At some point in the future I will try to send image data over a wifi module. Right now it's hard for me to help you since I don't know exactly how to do it yet.
Arduino digital output is 5V but the camera is designed for 3.3V. With those resistors I am creating a voltage divider that reduced input voltage of XCLK signal below 3.3V. You can use other resistors as long as the output of the voltage divider is below 3.3V.
@@IndrekL I used two 4.7k resistors so voltage to XCLK will be around 2.5 volt. But when I did the mid check as you did the green rectangle didn't came, I checked the connections, reduced the baud rate, reset the Arduino, still no change.

Hey! This is great news that you got it working! I haven't tried the wireless modules myself yet. Usually those are quite slow and it makes the image transfer more complicated.
It shouldn't be hard to add saving capability to the java application. I have a really busy period right now but I can add it at some point in the future.

Guys, if anyone is reading this comment, I just wanna let you know that this guy is the most helpful guy i ever found on the internet. He. has bern constantly helping me in doing this project. Lots if love!! Please support his effort!
Your question gave me the idea to make a video about it. Before that the ArduinoImageCapture project was just an experiment I did two years ago. Now I am thinking that sending image over serial rather than to the screen might be even better place to start experimenting with the camera since it requires less components. How did the test/exam/presentation go?
@@IndrekL The presentation went good, they understood the complication and I could explain why I didn't get output, and the fact that the interfacing would have been much easier with a fifo in the camera itself. So it went pretty much fine. This interfacing is part of a bigger project i am trying to do. (I would love to connect with you better, on mails or hangouts or anywhere else if you like when i continue with the project again) :)

Hey indrek ı am using Arduino UNO with 12Mhz crystal but i am having some problems ı can only run lowest resolution and two duplicate half Frame in your plugin monitor
The image window is opening up, I assigned the correct port and baud rate, but it is not rendering the red rectangle. What could be the issue(I am using Arduino Nano)
Hey!
Did you set "#define EXAMPLE 3" in "setup.h"?
Did you try with a plain Arduino without any additional wires beside the USB cable? The red rectangle is sent after boot-up, and sometimes the Java program can miss the frame. Try to press the reset button on the Arduino then the image will be sent again.
If that doesn't help try with a lower baudrate. In the "ExampleUart.cpp"set
#define UART_MODE 4
Now you have to also select 115200 in the Java program.

Yes, it will work with an Nano also. Arduino Uno and Nano are basically the same.
i applied all steps but i see only green image on java application i dont know where im wrong
all wirings are right, i checked them many times but when i run java application there is only green screen what must i do please help me :(
Green means that the camera is running at Arduino was able to configure the camera. Do you have any way to use an Oscilloscope? It would be good if you could check if VSYNC and Pixel Clock signals are working.
@@IndrekL you are right l have checked lt yesterday with a multimeter vsync has 0.30 volt heighest value and the lowest 0.05 volt and the code stucks at waitforvsync , what must l do whats your advice
Multimeter is probably too slow to detect the pulse since the pulse is very short. Maybe try to replace the VSYNC and Pixel clock wires. Perhaps there is a bad connection somewhere. Or the wire is broken.
@@IndrekL thanks for advice
Hello,can I use this cam for openCV ?
Hi, your videos were very hepful. I've followed your tutorial step by step. I had the red screen initially and then the Green screen at the mid-test. But whenever I connect the remaining pins, I also get a red screen. Am I doing something wrong?
Also, I have an Arduino clone, but it has an DIP atmega328P, so apparently it doesn't support 1M baud. Is it possible to reduce framerate so I can use smaller baud rates with a bigger resolution?
I'm trying to setup a camera to capture a Gray scale frame every 10 seconds and send it wirelessly via LoRa and then store on a PC. But so far I'm stuck at the camera setup, can you give me any hints?
Hey! If you get green screen and then red screen after connecting the rest of the wires then there must be something wrong with the rest of the connections that causes the camera to stop working. Maybe you can connect the rest of the wires one-by-one to see at which point it stops working.
Yes, if you play with the resolution and frame-rate you can get also higher resolution with slower frame rate.
What resolution and baudrate do you want? I can make the configuration and add it to the pre-set options in the "ExampleUart.cpp"
@@IndrekL Thanks for the reply!! :D
The day after I wrote that commentary I was able to get some footage from the camera.
I think the issue I had was due to using old jumpers, but I've already ordered a new pack of those as replacement.
So far in my project, I've managed to transmit data serially (software serial) at 9600 baud through the LoRa module I'm using to another module which receives the data and send it through an Arduino to a PC. (Theoretically the module can link at 115200 baud but I'm having issues changing it's default settings).
It's a low-power project where the camera is triggered by a motion sensor, like those in bathroom lights. So in my case I won't be needing constant "live" feed but rather a single frame whenever someones passes by and triggers the sensor.
The sensor takes around 8.6 seconds to warm up after each detection, which is the theorical shortest delay I'll need. So I guess any baud rate would do fine for me as long as I can send a compressed VGA image in less than 9 or 10 seconds. This motion detection bit is also already complete.
I've already tampered a little with your code and managed to get a feed on grayscale and VGA. But I'm not sure If I've configured It properly.
I think I won't be needing colors, but as much resolution and as low Blur as I can get, since my end goal is to use those captured and transmitted images on a facial recognition software or, at least, on a human detection software I'll build in python. (By the way, all the images I've got we're a lot blurrier than what you've shown at the end of the video. Is that just lens adjustment or It has some software settings involved?)
It would be great If you could help me out with the camera settings and clarify a little of what you've done in your code, so I can make a similar one that triggers with an Arduino output and sends the frame through SoftwareSerial().
(Sorry for the long text, I felt It would be easier to explain by giving some context of what I'm doing)
@@VitorJTekkRodrigues In this case you actually should use the FIFO version of the camera. If you use my code with slow frame rate and you want to capture a moving object (a person walking in front of the camera) then the image will be very blurry.
FIFO version of the camera can take a snap-shot very quickly and then you have time to send it over the slow serial line.
@@IndrekL If It manage to set up my radio module to operate at 115200 baud, would I be able to still use the non-fifo module?
Because I don't have a FIFO version and it's probably going to take a month to get It if I order one right now, and being a college project to be delivered at the end of August, I'm probably stuck with what I have right now.
@@VitorJTekkRodrigues If you want to capture moving object it will be distorted. Like here when the camera is moving 0:14
Fifo version will quickly capture the image into FIFO buffer and you have time to send it over the slow connection
Greetings Sir;
I would like to ask, after capturing the objects... I would like to save it to another folder for data file storge. How can i do it? Thank you for the kind respond.
Hey! The ArduinoImageCapture program has a save button to save the images onto your computer.
When i click listen it doesn't display anything, and the window of jdk closes, TX led on arduino is ON,, please help me to sort out it
Hey! I have a question.
I did a PCB with this and everything was working fine, and I was watcing the streaming in the Java screen. But then, I plugged another arduino to see some data in the COM of the new arduino and the Arducam stopped sending images. And now, I plug the arduino nando with the arducam and it does not connect, it aways appears a red rectangle. Any suggestion?
Hey! Can you still upload the code into the Arduino that is connected to the camera? If uploading code works then sending image from Arduino to your computer should also work.
@@IndrekL It is still uploading the code from Arduino IDLE. It is kind of strange due to it worked just but when I attached other arduino with its own COM it stopped worked. Sometimes it works and some times it doesnt :/
Maybe the problem is with the rxtx library that the Java project is currently using. It is old and not developed anymore. I should update the Java project to this instead: fazecast.github.io/jSerialComm/
This would probably solve the issue.

Can I ask you about how I should be save image from form to my local computer? And could be I compile this project like executable file for run on any computer?
I will add saving option to the java program soon. I have been asked about that a couple of times already but I haven't had time to do it yet.
I haven't done it myself, but it is possible to create self contained executable for java application. Here is one StackOveflow question about it:
stackoverflow.com/questions/2011664/compiling-a-java-program-into-an-executable
I did some googling and it is quite simple to use IntelliJ to compile the project into a .jar file that can be run by double clicking on it if you have Java installed (you also have to copy your platform specific rxtxSerial.dll next to the .jar file - for me it was win64).
If you want I can write more detailed instructions how to do that.
I haven't tried this myself but now it should be possible to use JSmooth to create an exe wrapper to the .jar file.

Thank you sir
Hey! Probably not. It's a different camera.
Also OV5642 seems to be much higher resolution than the OV7670, Arduino is too weak for taht.

BTW, I want to detect the moving(but slow) barcode by using ov7670 camera and arduino.
Can I have an advice from you?
I am not sure if the resolution is high enough. I guess it depends how close the barcode is to the camera.
@@IndrekL No problem. At first, I just want to make a prototype and can let the camera close the barcode.

4. Do you see any errors in the IntelliJ window when you run the Java application? (lower part of the IntelliJ window.)
hello where can I found the arduino code...its not in the description video.
Hello! Link to github page is in the description:
github.com/indrekluuk/LiveOV7670
if you click on the green "clone or download" button you get the code.
Hi. I followed all the steps but I'm facing the following issue: I run the java application and even though I click on Listen button, nothing happens. No error messages, no response from Arduino, no blinking LEDs (Tx or Rx).
What am I doing wrong? What am I missing?
What do you advise me to do?
Thank you in advance,
Hey! If you loaded the correct version of LiveOV7670 to Arduino then the TX LED should blink periodically (even if USB is not connected) since it should be sending out every frame.
Did you download the latest version from Github? I updated the LiveOV7670 project recently (there was one another person who couldn't get it working since he had an older version of the project).
Did you make the change in setup.h to:
#define EXAMPLE 3
@@IndrekL hi. Thank you for replying. I'm pretty sure I have the latest version of project. But I'm gonna check it out anyways.
Now it only sends data to pc if I press the reset button. But the.pc shows only the red image, which indicates it could not initialize the cam.
I'm using a dil 328P uno and I'll try a smd 328P uno andd check if it is a hardware incompatibility
If you see red then you most likely have the latest version.
Red screen means that sending configuration failed. There is either problem with XCLK signal or the i2c connection.
Do you have an Oscilloscope? If you have then you should check XCLK on the camera side. There should be 8Mhz signal on it. If this is OK then you should try to check if camera is sending out PCLK and VSYNC signals.
Can extract text by using this proxess
very useful, but is it the same way if i use wemos d1 r2 with ov5642 camera moduls?
sorry if my english is bad
Hey! I haven't tried to get it working with an ESP module (like Wemos) yet. ESP doesn't have enough pins to read pixel data, but maybe it is possible with some external chips like a shift register.
Thanks sir.. but,
Is it the same way if I use OV5642? Including using the same resistor?
Please,help.I connected my Arduino Nano to PC.I did everything as in this video
.But there is no red rectangle in Java programm. When I push reset button on Arduino,"TX" LED blink once, and in Intellij IDEA write "Unknown command code '6' " . Hope for help.
So,when i comment "CLKPR = 0x80;CLKPR = 1;" in "initializeScreenAndCamera()",i get red rectangle. Is it right?
Sorry this was my mistake. I thought I fix it for WAVGAT processor but it broke it for normal Atmel based Arduino. I will comment it out in Github.
So your fix is correct.
@@IndrekL In function "initializeScreenAndCamera()" interrupts are disable(noInterrupts). Is it necessary? I'm going to send bytes to PC only in certain cases. Can I enable interrupt while I don't send bytes?
Yes, you can enable interrupts while you do not need to read image from the camera. Reading pixels data from the camera is very time-critical and any interrupt that is triggered during that time will break the image.
By default there is only timer interrupt for "millis" that breaks the image. I call "noInterrupts" to stop that. Actually to disable "millis" interrupt setting "TIMSK0 = 0;" is enough. But if you add your own interrupts you should disable them also while reading image ("noInterrupts" will disable all interrupts).
Do you want to use an interrupt for the "save image" button? Wouldn't it be much easier to just do "digitalRead" in a loop?
@@IndrekL Of course I will use "digitalRead") I'm going to connect one more module to Arduino and maybe I will need interrupts. But maybe not, I still think about it. Anyway thanks for the help) If I have any more questions, I will write.
Hi. I have after run the application. It showed "Error:java: invalid source release: 12"

Man... This project saves me a lot of work! I was wondering... would it be possible to replace the USB connection with a RF transmitter with receiver having a Rs 232 to usb converter ? I am looking to have the whole thing wireless....Do you think it would work?
I think it should be possible. You have to find a transmitter that could transfer data at least 1Mbit/sec. Otherwise, it will be very slow.
I haven't had time to do it myself yet, but at some point in the future, I will try it.
@@IndrekL Thank you so much for your quick reply. For what I have plan it is fast enough I think. and I just need to capture a snap shot of the frame... By the way... on the PC side... is there any way to capture and save the image displayed? BTW... Look me up... you will see what I do... ;-)
@@dondixon4206 Yes, you can select a folder in the Java application and then all the images will be stored into that folder. Maybe you actually need the FIFO version of the camera? Arduino doesn't have enough memory to hold a frame. So it reads the image from the sensor and then immediately sends it out from the serial port. If the serial connection is slow then the image will have to terrible rolling shutter effect. The FIFO version of the camera can take a snapshot and then there is time to send it slowly over the serial connection.
@@IndrekL Aha! I figured that. Yes. I will ask for the FIFO version. Thank you so kindly!

Hey Indrek, Thanks for the video, i'm getting a clear green and red screen, however when i try to capture the camera it's shows me a gray glitch screen. Do you know what the problem could be?
Check the wiring. The clock signal may be noisy. Maybe try to use shorter wires.
@@IndrekL THanks for the quick reply. Used short wires on the clock, but still getting this bad signal
@@telband5314 Try lowering the framerate to see if it gets better. Try
#define UART_MODE 4
@@IndrekL That seems to stop the gray glitch screen, however now i got a more colored blurry screen...
It seems to me that the clock signals might be noisy. If you have an Oscilloscope then you could take a look what the signals look like. But maybe try to solder the XCLK and Pixel Clock wires instead of using a breadboard.
Can I use this camera to process images for “ Object Recognition “ ?
there are better options xd try "PixyCam"
May i know why you use 10K, 1K and 680 resistor?
Hey!
10k is common practice for i2c pull-up resistors.
The camera module's input signal must be below 3.3V, but Arduino output is 5V.
So when I build a voltage divider with 680 ohm and 1k resistors then the output will be about 3V, which is good enough for the camera.
It probably will also work with two 1k resistors or two 680 ohm resistors (or any resistor in that range) - then the output would be about 2.5V
The total resistance shouldn't be too high since then the signal starts to deform. If it is too low it will consume too much power (Ohm's law). With 1680 ohm total the signal pins voltage divider will consume 5V/1680ohm = ~3mA, which is low enough.
hi there, whenever I open the terminal window in IntelliJ Idea, it gives me an error every time. it says " WARNING: RXTX Version mismatch

rxtx.qbang.org/wiki/index.php/Download
"TODO: The 2.2pre2 bins contain the 2.2pre1 jar file and the 2.2pre2 native lib which causes a mismatch warning"

It probably is possible but it will be really slow.
how about using wireless module? nice video!
Sir i am getting a corrupted red rectangle at 3:49 some black lines coming at the end of the red rectangle
Are you using an original genuine Arduino? For some reason 1000000 baudrate does not work properly with genuine Arduino. You have to lower the baudrate (which also makes the image much slower). If you try it with a Chinise Arduino clone that use the ch340 serial chip then you can use 1000000 baudrate.

Hi thx for the tutorial! After I uploaded the code to arduino, I got a blinking RX instead of TX. I didn't see a green square at the midway check point but I was able to get glitchy images that are completely unreadble. Any suggestions?
Hey! If you try with an Arduino WITHOUT any wires (just a plain Arduino connected to you computer). Do you get a clean red square? If you can see clean red image then we can be sure that the Arduino to PC side is working.
@@IndrekL Yeah I can get a red square.
Then try to check the wires.
The most critical is the XCLK wire to the camera. Try with shorter wires if possible.

@@IndrekL ohk sir looking forward for your help . Thank :)
Hello, great tutorial but my frames have some stuttering, how can I fix it?
What does that mean exactly? Can you make a screenshot or a video clip of it?
@Indrek sure, it`s like this drive.google.com/open?id=1CZR1HocQfSJmfNGSRyVyZOctc_nSX2sU
but my `lines` appear only on the right side of a frame
Is it necessary to use 680 and 1k resistors for XCLK?
Arduino digital output is 5V but the camera is designed for 3.3V. With those resistors I am creating a voltage divider that reduced input voltage of XCLK signal below 3.3V. You can use other resistors as long as the output of the voltage divider is below 3.3V.
@@IndrekL I used two 4.7k resistors so voltage to XCLK will be around 2.5 volt. But when I did the mid check as you did the green rectangle didn't came, I checked the connections, reduced the baud rate, reset the Arduino, still no change.
@@abanvarghese4000 Maybe 2 x 4.7k is too high and the clock signal starts to deform too much. Do you have two resistors somewhere between 100 and 1k?
@@IndrekL Okay I'll try with smaller resistor values and thanks for your help.☺
@Indrek Now when I connect all the pixel data lines, the image capture window pops up. When I set the baud rate and press "Listen" the following error is displayed:

I did anything in the video but after click "listen " nothing happen
You should see at least a red rectangle. Did you select the same COM port number that you used in Arduino IDE to load the LiveOV7670 code to Arduino?
@@IndrekL yes i did. i changed . but still not red rectangle or anything
@@tuanbui-yg2po Click on "Listen" and then push reset button on Arduino. Do you see the "TX" LED light up on Arduino?
@@IndrekL after reset the Led near TX RX is blinking but TX RX is still off.
@@IndrekL Yes after clicking Listen the tx led glows up for few seconds then it turns off...and nothing is coming in Image capture nit even the red square
Can i decrease arduino code 9600hrz
Do you mean baudrate of 9600? It would way too slow to transfer image data.
@@IndrekL yes l know but hc05 not working at 115200
I did it. bluetooth hc05 module causes error 115200hz decreased it to 57600hz and image format is grayscale it works well know thanks for your share about ov7670
Hey! This is great news that you got it working! I haven't tried the wireless modules myself yet. Usually those are quite slow and it makes the image transfer more complicated.
Will this work for the arduino Due?
Currently it doesn't support Due. Due has completely different processor compared to Uno/Nano/Mega
This was really impressive... Is it possible to send the image as a message to a phone?
Currently, I have only made it work over USB. Theoretically it should be possible with a WIFI module to send it over network to any device.
Thank you very much. Very useful video for me. My OS is windows. Does it work on my computer?
Yes, you can download java and IntelliJ for Windows.
Не работает библиотека для win64. не видит их от слова совсем
Thank you for this video!I have a question,how save image on PC?
It shouldn't be hard to add saving capability to the java application. I have a really busy period right now but I can add it at some point in the future.
@@IndrekL It would be great!How soon could you do this?About a month?
@@mishayakubchuk4192 I'll try to find time to do it within a month.
Hey!! I am so happy you made this video! I have been working on this with your help, and I will continue again after my exams. Guys, if anyone is reading this comment, I just wanna let you know that this guy is the most helpful guy i ever found on the internet. He. has bern constantly helping me in doing this project. Lots if love!! Please support his effort!
Your question gave me the idea to make a video about it. Before that the ArduinoImageCapture project was just an experiment I did two years ago.
Now I am thinking that sending image over serial rather than to the screen might be even better place to start experimenting with the camera since it requires less components.
How did the test/exam/presentation go?
@@IndrekL The presentation went good, they understood the complication and I could explain why I didn't get output, and the fact that the interfacing would have been much easier with a fifo in the camera itself. So it went pretty much fine. This interfacing is part of a bigger project i am trying to do. (I would love to connect with you better, on mails or hangouts or anywhere else if you like when i continue with the project again) :)
Thanks for recommeding him. His videos are good indeed.
So just picture. No video?
Yes, the serial communication from Arduino is very slow.
I have a red square! Noob + red square = happy = subscribe. Thankyou
Thanks! Have you already tried the next step of connecting the camera to get the green square?
Nice video shot, thanks for sharing it, keep it up :)
Is it possible without usb ?
Yes, possibly with a wifi module.
I lot of time searched good explanation, how work with VGA&Arduino, and I did it. It was amazing! Thank u very match! From me respect, subscribe & like!
Thanks!
@@IndrekLhii sir
Where i can get arduino code?
Link to the github project is in the description box.
is it work with esp8266 controller
sir replay me
Hey! My library doesn't work with the ESP8266 at the moment.
ESP8266 only has 11 available IO pins and it might not be enough.
@@IndrekL tq for quick replay. sir plz suggest me a library which works with esp8266 i just need to see the captured pics im my pc
Maybe you can check this: ruclips.net/video/XqfSz1jZ2JA/видео.html
It uses ArduCAM mini instead of OV7670
@@IndrekL tq sir i will try this one
can you please make wifi streaming
can i launch it on Mega ?
Yes, it works with Mega also. Connections are a little different: github.com/indrekluuk/LiveOV7670#connections-for-arduino-mega
İf it is possible how
very useful..thank you!
Nice thanks for this video
i can't run the app
What is the exact problem or error you got?
