- How to Read and Extract HEX File from Arduino Board And Upload the HEX File to Another Arduino. In this video I'm gonna show you
how to read hex file from Arduino board and extract hex file from Arduino board , copy the hex file from Arduino board to pc , burn/upload the extracted hex file to another Arduino board , read and extract .eep file (EEPROM file ) from Arduino board and burn .eep (EEPROME file) to another Arduino.
how to read hex file from Arduino board ? here we are using Arduino as isp mode to make an Arduino as isp programmer and connected the target Arduino to Arduino isp programmer and by the help of Avrdude we can easily extract hex file from arduino /copy code from arduino board or extract code from arduino board.
Avrdudess is an avr chip programming software it have various options for setting configuration bits like fuse bit lock bit and also we can read back the fuse and lock bits from the chip too.
by this Avrdude software we can get hex file back from target arduino board.
you can upload this hex file to any other same type arduino or the same type microcontroller with same crystal speed also you can simulate this in proteus
Someone asked me about Arduino uno hex file download that 's what we did here. read back hex file is possible but someone asked me
how to retrieve sketch from Arduino ? , it is not possible to convert the hex file back to the sketch / c++ code but we can burn this hex file to any other same type arduino or same type chip/MCU running at the same clock speed.
now we extracted the hex code from arduino successfully , here we copied program from arduino uno by the same way you can copy any avr microcontroller's / Arduinos
how to upload hex file in arduino ? here we are introducing two methods to upload hex file to arduino the first method is the easy method by an application called xloader. by this application you can flash a hex file or burn hex file to arduino very quickly and easy.
The next method is the advance one by avrdude by this method you can program not only Arduino's but also most of any avr microcontrollers , also you can write eeprom / .eep file , hex file, set config bits and also you can read back from the chip. avrdude is a great tool for arduino/avr microcontroller hex file download and upload.
Someone asked me about flash hex with arduino ide which is not possible but the arduino ide always generating hex file in the compile time of a sketch and which is saved in a temporary location C/User/User name/AppData/Local/Temp/arduino_build over there you can find two hex file one with the bootloader and one without bootloader. always you can copy those files if you need with out closing the ide. remember it's a Temp file its only there when the arduino ide is not closed.

IMPORTANT NOTICE:
After watching this video so many of you asked. how to do this with uno as the programmer and the mega as the target , mega as the programmer and the mega as the target.
and many of you guys requested the wiring diagram for that again and again and i helped many of you around the world through email. You know, answering tons of emails is so hard but that's not the case there is a probability to miss some of them. I don’t want that to happen like that. So I updated the video description. You can download those digram's from there. Even if in any case I miss your mail.
Have a great day.
Thank you .

You did great job. Can you help me to get hex file from STM32F030K6T6 microcontroller and write it to new one.
I tried this method and it detected MCU as ATmega328p and Fuses & lock bits still remains same as 0x00 but it says SUCCESS: Read high fuse
SUCCESS: Read low fuse
SUCCESS: Read extended fuse
also SUCCESS: Read lock bits
I'm waiting for your advise. Thank you. 😊
I did not think would ever find a way to read/copy a hex file but here you are. Such a great help to me. I burned up my 3D printer board can still talk to it so thanks to you saved me a lot of work. : = }}
You are welcome. 😊🤝❤️.
I would like to also say thank you for taking the time to create, edit, and explain every detail step by step. You must have spent DAYS putting this together. Thank you again, sir. It has been a tremendously big help.
👊☺️
Hi, I really appreciate your video, detailed guides and attached resources. You have no idea how much it helped me. Although I couldn't make it work with 2 MEGA's as programmer and target, I repeated the steps using an UNO as the programmer instead, and it worked!
Thank you once again!
This was so helpful. I can verify it works with Ardunio Leonardo, but the ICSP header must be used as the pins are different. It also works with Arduino Micro. Much easier than using Microchip studio in professional mode. Thank you Aneeshmurali !!!
Good to see you ❤️🤝

Hi! How can I know what to put on the fuses, I only have the files. An error appears ....
Amazing content sir it really helps me thanks 😊
hallo first is to thankyou for good explanation I'm glad i understood you very clear and was able to program using .hex its very nice of you thanks man
Hi! I am new to working with microcontrollers and was wondering if doing this is possible with different models such as using an GENUINO MEGA2560 EVAL BRD GBX00067 to an ARDUINO MEGA 2560 REV3 A000067. Thanks!
Yes possible but different chips have different fuse and lock bit configurations.

how to know which code upload in atmega8 and how to get it back /COPY
but i dont hex file etc..
What if my no name brand of UNO board is not listed on the Arduino software under "Board/type"? I get this error: avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xfd
Do selection manually.
Make sure the port selection was right.
Keep the programmer type to usbasp.
Then upload if everything is normal it will work without any issues.
If you getting any issues again try to reinstall Arduino ide.
The clone version of arduino's are made with usb to TTL chip it doesn't has any firmware on it. So if you connect this kind of board to the computer it will show only the port number of the connected serial chip. Sometimes with the name of the serial chip like ch340g Ftdi etc.
But the original version of arduino's has a dedicated microcontroller with firmware on it. which is doing the same job as the serial chip. and the name of the usb device is embedded on it . That's why we can see the name Arduino Uno , etc like that.👍
If you are interested swap a usb to TTL serial chip with atmega 328p having bootloader then you can make your own Arduino at home just by yourself.😊🤞👍
@@Ciiads thank you, but how do I reinstall Arduino ide?
Just uninstall and go to the Arduino official website and download and install it again. Pretty simple
Brother I need your help!!!
I have a 8pin SMD Microcontroller which controls my pixel led belt and yes it is from China so no marking on the IC and also no datasheet to look for. As I physically inspected and found that pin 1 is (+)voltage ,pin 5 is (-) negative and pin 8 is data out others ar Not connected anywhere on the pixel belt!! Now I researched and found Pic12F675 closest to it as the pinouts match.Now the help I want is that pixel belt is almost destroyed but the 8 pin SMD Microcontroller chip is still good and functional,so I want to Copy That Chips Programme so that I can use it on Arduino to controll my WS2812 pixel belt which is better and has more led!!Is there any way so that I can hook up the Data Out pin from the Microcontroller to Arduino and copy it's effects and create same effects code on Arduino and use it with other pixel belts??? Hope You can Understand and help me;
If you truly believe it is pic 12f675 and the chip is not locked then you can copy the program using a programmer called pic kit. but the program is not portable to other mcu's. because of the architecture and the instruction set, registers, memory mapping,io peripherals, address, are different in mcu's to mcu's. But it is possible to the same chip. its not like the way we are installing apps on our phone pc etc that will work phone to phone or pc to pc because of the instruction set's are the same.
and it is not possible to create the same effect on Arduino by the copied program. But it is possible to write a new program like the way you want to create the same effect.
and the last thing you mentioned probably have a chance to success.
If you accurately copy the timing of data signal.
then you can regenerate that using Arduino or any microcontroller but it is hard to copy the fast square wave like that. a percent of error will affect the system badly.
Thank you very much for the explication!!
You are welcome!
i flashed my arduino uno board using flip and now i cant find it in the device manager or ine the ide software(COM number) i want to reprogram the board what should i do
thanks
In the device manager you can definitely see the com port of the connected device. If it's not showing the connected device. Then that might be a cabling issue or the connected device may be faulty or may be your arduino board is based on some serial chips like FTDI or ch340g etc. If they are based on serial chip like this. then , on the device manager show's the name of the serial chip with appropriate port number not the name "arduino uno". literally arduino clown's are based on serial chip's.
May be the flip erased firmware of your primary microcontroller (mega16u2) on the arduino board which is acting as a usb to serial converter for the main chip atmega328p. With out that it will not communicate to the pc and back to back. So Reflash that chip if the firmware is available. or replace that mega16u2 MCU with a serial chip like FTDI or ch340g etc that will do the job fine.
For about Reflashing firmware of mega16u2 check this blog that may be helpful for you www.instructables.com/How-to-Restore-the-Arduino-UNO-R3-ATmega16U2-Firmw/
Thank you 😊.

Thank you , appreciate that.
hi thanks a lot i tried so many ways to load a boat loader and it fails but when i used your way in avrdudess it succeed and it is much easier than aurdino thanks again
😊🤝
Does the method explained in you other video "How to Stop Cloning Your Arduino Atmega328p Programs, Do This" prevents the ".HEX "file to be read by the method explained here ???
If not, then the protection agains cloning would not be efficient...
Thank you for your reply,
Normally Arduino doesn't have any protection so you can read the hex file back like this but if you want to prevent that then that's the way to do it, it will bit lock the chip.
@@Ciiads OK, so if we set the "Lock bits" and "Fuse bits" as described in your video "How to Stop Cloning Your Arduino Atmega328P Programs, Do This", it should be impossible to read the ".hex" file, even with the method explained in the video on this page.
So you have answered to 2 different problems: how to stop reading .hex file (if we want to prevent reading) and how to read .hex file if the programmer has not specifically used the lock bits.
Congratulation and thank you.
Very useful 🙏

Hi can we see/get Arduino program also from hex fix
Hi, informative video.
Been wanting to send HEX data (Register values and address) from one Arduino uno to another via Serial Communication. Not to forget trying to not convert the HEX data into Char, as would be needing the HEX data in the slave Arduino to perform some functions. Could you please make a video on it?
Regards
Thank you for explaining this. I tried this using 2 Arduino Mega boards and failed identify the MCU)-p). I selected ATmega2560 in MCU and also in Presets without success. I wonder, is there a difference and if so, what? Asking as I lost the libraries that made a TFT screen work, but was hoping to grab the info off a working project..... Hate TFT's listed as X but not X,Y or even Z :/
Arduino mega have some pinout difference. That's the problem.
So the wiring diagram is also different.more over that we need a different Arduino isp sketch for Arduino mega's.
You just DO NOT erase the Arduino mega having your valuable program.
We can take that back from it.
Don't worry about it.
but you never get your library and source code back.
The compiled executable file (.HEX) is the only thing we can get back from it.
Although if you got that file it is impossible to get the source code, but you can make many copies of your project.
Do you have any Arduino uno board ?
Then we can make a try without changing the Arduino isp sketch.
and i will forward you the wiring diagram.❤️🤝😊
@@Ciiads Thank you for the reply. Having a copy of this program I can load onto a new Mega is the most important part, at least then I can replace one that's bad while I try to find a library/model number combination that works with the Arduino sketch I have.
I do have an Uno as well as a a couple of new-blank Megas, so which ever combination is best or easiest.
And thank you, I've been going nuts trying different things to get this going again, so I'll be awaiting the wiring :)

okay fine, i don't have any Arduino mega right now but you have it.
That's enough .

We can talk about it. of course we can try with two Mega's.
Just contact me through mail.
Then i will contact you and we can figure it out.

@@Ciiads email sent :)
@@2112user okay, got it🤝
to do what you have in this video is very simple one just need a rs232 port and PonyProg (free downloadable software) on your computer and a simple diy adapter that plugs onto the Arduino's icsp , one can then copy any code (hex file) from a Arduino in seconds. one can also load a hex the same way. even read/write the fuse setting.
There is so many ways to reach the destination but the choice is ours which way we want to go. This is just one of them.😊🤝
I wish there were more videos on serial port i/o projects. We've had the world at our fingertips all along. Great video and great comment! Daft if you have the time and know of any serial links to explain your process, I'd love to learn. I'm learning avrdude from the terminal today on a pi to see if my arduino is bricked.

Hey, can i use this progy to my esp8266 nodemcu? how to make it run
What you mean progy. Whatever, it's not gonna work with esp8266. ESP is not AVR.
It's Possible to extract program from 89c51? if not lock. any video on that? please provide me information link.
The steps are the same for every avr mcus but the difference is.
you have to browse the programmer , port ,and chip according to what exactly you connected.
you can always follow the same circuit diagram that you used to write the hex file to read the hex file back.

Hi Aneesh bro I need some help!!!
I have PIC18F452 controller with protected fuse code.I am extract hex but it contains fuse checksums code protection any idea remove parity bits. Thanks
did you know the meaning of protection. I'm just kidding .
No brother no way.
if you do anything with the locked chip or if you try to change the config word it will erase the chip. but there are techniques of reading protected chip which require high end equipment like electron microscope, etc which is way beyond the reach of enthusiasts. and that is illegal.
The methode is like decapping the chip and read it out with an electron microscope, or selectively resetting the security bits with UV light by somehow masking out the rest of the die but I'm not sure about the success rate and nobody will attempt to do that because it is impossible to do. if i were you i will write a new firmware my self. which is far more easier and better than attempting to copy a protected chip and wasting valuable time.
if you are curious in embedded electronics then work on your skills. I wish one day you can write your own firmware your self. the learning curve is about miles long but the time you drive on the road will worth it.

Can we use arduino uno ic atmega 328p in profession industry for real time sensors and for industry innovation like arm,,,,,,with no issue ,,,,because many industrial professionals saying that arduino uno is not for industry use,,,,it's just for kids projects and will not suffer well In professional industries at all,,,,,please help me on this sir,,,,,
I agree with this. That's true. Arduino Uno was not for industry but there is nothing wrong with atmega 328p. Nobody use development board for commercial purposes right. But you can use the chip 328p for commercial designs but use proper toolchain for the embedded system development. Like atmel studio it is the official ide for avr mcu development. it's not easy as you did in arduino ide. you need to write you'r own library and code for your project. and the project is yours you can market that.
arduino ide and the library's that came for arduino and the hardware it self is opensource.
Because of this reason it's not well optimised and not Bugg free more over it's opensource too.

How to convert that hex file to .ino ??
I want to make changes in it.
It's not possible, for instance, you wrote some alphabet on a glass piece and then powdered it to make glass powder but you can't ever make the exact glass piece having the alphabets from that glass powder.
can we read file hex from arduino that has been lock bit?
It's complicated. 99% no chance but 1% there is a chance when you erase and reset the lock bit with out erasing the chip that is not possible but if you can it's possible.

Getting "WARNING: Unable to detect MCU" Any suggestions?
This is exactly why I ALWAYS protect my code from cloning by using the fuse bits....
Lock bits ☺👊
life saver
Welcome 😊❤️❤️❤️
Thnx for your detailed explanation..
I promised you 😊❤️👍
@@Ciiads one more doubt. If fuse bits are set in mcu how can we know that ln avrdudess that this mcu is protected.
I tried to read a mcu which is found in a pcb ie attiny88 but i received an empty hex file. What does it mean? Its protected or anything wrong with my connections or settings in avrdudess. Please help
I just follwed the instructions in video no changes done like baud rate and everything kept as per ur video. Do i need to change anything as the mcu changes.?
Wow another amazing question ,fuse bit's are not the villen here. mcu code protection is based on lock bit.
Okay came back to the question , if you want to check the chip is locked or not you just read the lock bit value. Then you can identify its locked or not and one more thing in case if the chip is locked then you think you are going to change the lock bit and read the hex its not possible if you change lock bit it will erase the memmory. So you didn't get any thing.
Ok in order to know which is the locked and unlocked lock bit value i prefer refer the chip datasheet or just look around avr fuse calculator its an online calculator for avr.
Ok in the case of Arduino's which is not locked in any mean ?
Have a great day
How can we convert hex file into arduino code? I want read hex files to understand the arduino code.. How can i do that...

No because inside mcu everything is binary you can read back and generate hex file. The executable/compiled file.
But not the source code.
In case If you get any decompiler still you can't convert that into the original source code that you wrote before. But you can make the equivalent source code that actually works and it is really different than the actual source code.👍🤝❤️

Yes you can.
only thing you want to do is just bit lock the chip.
keep all the fuse bit and extended fuse bit values to arduino default except the lock bit. you can set the lock bit value to disable the read from the chip.
Do you want to know about the lock bit values and their purpose.
Just refer atmega328p mcu datasheet or use avr fuse calculator it's an online tool. Just google it you will get there.
i prefer to remove the bootloader from the chip that will permanently disable the read/right function through uart serial port of the chip.
and bit lock it to disable the read through isp,icsp method then your software is protected.

@Zasa Saza
Sorry for your situation but No way.
this is the way to program avr chips and read back hex file,setting fuse and lock bits etc . reading the chip that is only possible when the chip wasn't protected , Arduino's are not protected .
Make sure, first of all,make an arduino as an isp programmer by uploading arduino isp sketch to it and wire this board to the target arduino 10 to reset, 11 to 11,12 to 12, 13 to 13, 5v to vin, gnd to gnd
Where is your problem happens? reading hex file from arduino or writing hex file to arduino?
did you configured the fuse and lock bit configuration right?
What is the message showing on the black window of avrdude when programming?
Can you forward the circuit diagram and hex file that you having trouble, let me check and i will figure it out don't worry i will help you and reply you the solution.

If you want to just burn hex file to arduino the program called xloader will do the job. Which is very easy just select board type and connected port then just browse hex file click upload that's it. Few Simple steps.
Download xloader : mega.nz/file/37AWwCgb#GIPCwiRaSYPW6kNxVA10p77ufQeL40tuPJ6fGJjcOjU
If you want to know why are you struggling with avrdude and my tutorial. i have no idea about what you done there please forward the hex file with circuit diagram to my contact . Let me check and verify and i will reply you the solution don't worry I'm with you we can fix that 👍
I got your screen shot in my mail in my observation you didn't selected the currect programmer type select programmer type to arduino. And follow the video with out a single seeking because everything is important. If your lcr meter running at 16mhz then keep my same fuse and lock bit configuration and don't forgot to check the box next to it while programming Please check my reply on your mail 👍
I'm waiting for your successful message❤️❤️😊🤝👍
@@Ciiads 👍 Thx
Good morning And Good day,
In this video you have uploaded blink file in arduino first then extract the same with the help of averdude. If program is already installed in arduino then how to extract the same.
With great request make video for the same.
I didn't get your question, this video shows how to get the program (HEX file) from a programmed Arduino, after getting that file you can burn that to another Arduino having the same MCU and clock speed, here I showed an example like copying a blik program but the procedure is the same for any kind of program that uploaded to the chip.
In summary
In this way you can copy the program ( executable HEX file) from an Arduino you can flash that to another board and make a copy of it, however, it's not possible to convert the executable file back to the source code like what have you wrote on the sketch.
Thank you.😊👊
Thank you very much taking immediate response to my comment .

Good morning And Good day
When write blink.hex file from programmer arduino to target arduino and target arduino start blinking. Then programmer became empty or loaded with blink.hex file.
With great regards
Sharad
Here we are using one of the Arduino as a programmer after burning the Arduino as an ISP sketch, and then we are using that programmer to read or write hex files to or from the chip(target Arduino) so we are using the programmer Arduino to read from the chip or write to the chip so it's not gonna do anything to the programmer if your programmer selection was right.
Please watch the video carefully it's not for entertainment it's serious stuff so everything is there thank you.🤝
i used two arduino uno or how to conected write thank very much
Sorry I can't understand, could you clarify your question please?. 😊❤️👍
sorry i want to get the program of arduino nano,can you show me how connect wire betwen two arduino nano,thank very much
@@kithuatvasangtao121 for nano wiring is same as uno. Keep the same pin name . That's it. 😊👍.
thank you very much
plase help me,i had to get program arduino nano by sofware avrdude but when i write a program from ide arduino upload to board arduino nano again is error ,thank you
avrdude error: invalid -P value: 'COM4'

how to convert hex to c++
It's not possible but it will when you find a decompiler for it, and i didn't find any, even when you find and decompile the decompiled source code is very different than the original source code and it's very hard to understand.
If I were you i will write a new firmware for the particular application myself.

how to translate hex file into arduino program? thats the question
Actually, the hex file is the program
Anything you wrote on the Arduino ide or any ide is called source code
Here, the source code is based on embedded c or c++
At the time of the compilation of the source code, the compiler translates that into the machine code like instruction by instructions according to the specified MCU Like we wrote the program in assembly (opcode and mnemonics) remember.
So if you want to translate that hex file code back to the source code is possible by a decompiler program if it is available but it is a machine-generated source code it works but it will not be the same as the original source code. I mean the variable names constants and function names and everything is different in there because it's a machine generated source code. So it's very hard to edit and debug.
and always if you are skill full guy
You can transcribe the hex code back to opcode and mnemonics (assembly code)
Manually by referring the instruction set and the architecture of the mcu but it's a time-consuming and a painful process
If I were you I will write a new code for my application because that's very easy for me.
Thank you for your question

@@Ciiads thanks, i hope someone make this convert tool very soon
Anyway, decompiling a hex file will not give you the exact same source code that you originally wrote, as the decompilation process is not perfect and can introduce errors or inaccuracies.
There are several reasons why the decompiled code may differ from the original source code. One reason is that the compiler optimizes the code during the compilation process, which can result in changes to the machine code. Additionally, some compilers include code obfuscation techniques, which can make the decompiled code more difficult to read or understand.
Another reason could be that the libraries used in the project could have been modified by the developer and the original code is not available anymore.
In general, it is not recommended to rely on decompiled code, as the results may not be reliable or accurate. If you need to make changes to your Arduino project, it is best to start with the original source code.
when you say arduino it sounds like you saying " I Don't know" :-D but you do know !§!
Well, you get the point that's the whole point 😊👍🤝.
I will keep that in mind and improve next time.
Thank you.
hi,nice video..can upload ASM file too?
First you wanna compile that asm file to hex.😊👍
@@Ciiads asm to hex,can use avrdude or xloader?
@ocang alan ocang
asm is just a source code. Just compile the source code then you will get the hex file and it is the compiled file that is understandable for every programming softwares that build for. I don't know about how or where did you wrote the source code but there will be always have an option for compiling your source code on the same ide that where do you wrote the code.
@@Ciiads how to convert? im sorry,im newbie
@@ocangalanocang8758 just compile the asm file bro. That's the one and only way

Arduino mega to another Arduino mega program copy 😘
Please make a video about how to lock the hex code inthe arduino chip, thanks
Please because this is very important for me. thanks
Of course I will
Which arduino board now you are working with ?
Arduino nano atmega328p au
Also include the pro mini (same chip)
Please make the video thanks
