How do I change the eye animation to make it bigger? so that the LCD can be full? Thank you, I have subscribed to you
Please, How do change the eyes animation to full screen for my TFT round display and change my gift animation from smartphone.
I have been trying for weeks to get “Uncanny Eyes” working on the 240x240 display and I finally found your channel. Excellent presentation and it works!. I’m anxiously waiting for your update on making the eyes bigger and centered. Then I’ll be able to incorporate them into a plastic skull for my grand nephews. Thanks again.
thank you very much bro! I had a big choice between "Chinese copy" and "Waveshare" display. I can't afford an expensive display from Waveshare and I was worried that the Chinese display would be worse, but thanks to your video, I realized that this is not the case and that the Chinese display is fine for me. Thanks again, this is the only video that helped me
Small suggestion... When I started working w/ config files many years ago I was told that MS notepad can corrupt them. Notepad++ has always been at the top of recommended editors. 👍
Never had a corrupt issue with notepad from Windows
Just found this and will watch it all with interest as I want a moving eye for my Mad Eye Moody cosplay.
Fun Halloween project. Got a little lost regarding everywhere the "CS" value needed to be commented out, but got it figured out. Thanks for another fun video.
Good video mate helped a lot!
Saludos amigo!!!
Excellent video. It worked perfectly for me. Thank you very much.
You're welcome!

How do I change the size of the eyes, sir? so that it can be maximized with the TFT LCD
Thank you
Thanks!
Thank you, it's appreciated!
Good morning my dear friend: it is with great satisfaction and joy that I comment that following your tutorial and file I managed to make an eye work. There was a video from another youtuber that I followed all the steps but I never managed. Fortunately your video is complete, didactic and simply sensational. Congratulations. I already subscribed to your channel and I wish you a lot of success here. I'm Brazilian and I didn't find any tutorial in Portuguese and yours is easy to follow. I used the subtitle to translate. Thanks
Note: I'll see if I can get both eyes working and use a joystick.
Thanks a lot!
How do I change the size of the eyes, sir? so that it can be maximized with the TFT LCD@@thelastoutpostworkshop
A great video. You managed to help me get these eyes to work! Subscribed and many thanks.
As a few other people on here have asked, is there a way you know of to increase the size of the eye to better fill the display? Or at least a way to centre the eye on the display instead of having at the top of it?
Thanks. The eyes are fixed image, so there is no easy way to make them bigger.
@@thelastoutpostworkshop
I spent some time trying to find a way to reverse engineer the eyes from a C code array back to an image so I could resize it. Or at least understand how the image looked in the first place. No luck. Thanks for replying.
With a realsence point cloud camera you can send OSC coordinates to the esp and track a human then have the eyes follow a human
thank you for your great tutorial. everything works well I just have a question for the position of the eyes in the center of the screen on the X axis no problem but impossible to adjust the Y axis
Best detailed video I found, congratulations. Would it be possible to implement eye control with joystick? Thanks
Yes, absolutely
Very nice work and a cool project. Nice job on the instructions as well. Got mine working the first try! Just wondering why you put the eyes so far to the top of the screen and not centered?
I have tried without success!
Hello Sir.... thank you for your video tutorial. Very interesting project.
I have question :
how to change the eyes type by switch? I think it would be very cool to change the eyes type animation by using a switch.
Interesting project, did you manage to make the eyes bigger?
Thanks for your videos.
No the images are fixed size
Thanks for sharing great work. It works perfectly, I'm looking for a way to remove the eyelids but I don't know how to do it. Do you know how to do it? Thank you
Thanks! I don't know how to do remove the eyelids
How do I change the size of the eyes, sir? so that it can be maximized with the TFT LCD
Do you know any other round display of no more tan 2.1" that does not have that anoying notch at the bottom? Like those in commercial smartwatches
hi, great video thank you! can you tell me how to change the size and center it please?
I am going to release a video on it soon
Useful and interesting video, thank you. A quick question if I may - do you see any noticeable difference in display quality between the one bought from AliExpress vs the Waveshare?
Absolutely no difference
@@thelastoutpostworkshop cool, thanks.
Do you have any videos or posts on how to configure two IR temperature sensors like the MLX90614? I'm trying to use a multiplexer but I'm a little stressed trying to get the temperature from each sensor. I want to make a tire sensor for my race car. I'm good with mechanics but bad with programming. Thank you. Nice tutorial.
Sadly I do not have a video on this
how to change the position of the image so that it fills the screen?
How can you make the eyes bigger?
Very good work
Thanks
I tried with no success!
can the eye display bigger ? seems like a waste of monitor size?
thank you, it worked;) and you can enlarge the eyes for the whole TFT ?;)
Thanks, no they are fixed images
@@thelastoutpostworkshopToo bad, I wanted the eye to be on the entire display :) 😊
Thanks for the nice project discription. I am not that experienced with Arduino so it is a good practice. I build it using your latest software. Loading without problems. I connected one of my 240x240 tft display with pins as seen in your video. Now get an error gpio: gpio_set_level (227): GPIO output gpio_num error. Can you help me solving this?
8:19 - Hello, Super Video - Question: I am looking for a tutorial for the very interesting 40x160 display with the GC9d01 driver - is there any information on this? Thanks very much
Interesting, I don't know this display, do you have a link to it ?
Love the video but I wanna add another type of eyes can you help
Can you transmit video from a runcam3 with these? If so is it as easy as just connecting the run cam and 1.28 lcd screen together ? It’s for a digital night vision build
I don't really know, I have never used a runcam3
@@thelastoutpostworkshop thanks for the quick reply.last question though what about transmitting video at all? Are these 1.28 lcd screens capable of doing that besides animations or clock viewing?
May transmitting video over wifi
Is there any support for micropython?
Thank you for this video, it is really helpful! I have a question please, how to increase the position and the size of the eyes? I know these are small displays, but the eyes are up there in the upper "corner" and they could be in the middle and a tiny bit bigger. I need them bigger for a project... Also, is there a way to create custom eyes? Could you do a tutorial on that?
I never tried to change the eyes size and position, good idea for a future video.
@@thelastoutpostworkshop I am sure it would make other people happy too, I was trying for hours yesterday, but I am bad at programming..... ^^ The initial build works like a charm! Your tutorial is really great!
Hey w do I load other animations
I have zero knowledge about this but wondering how you powering that testing board? Does it use the power of from esp32 usb supply?
Yes it is powered through the usb cable connected to your computer
hello, How can you make the eyes bigger and centered?
You can't since the eyes images are fixed
Thanks for video, I have solved flicker problem, THANKS!!! A question, eyes are made for 128x128 screen, do you know how can set it for 240x240 display size?
If I change
#define SCREEN_WIDTH 128
#define SCREEN_HEIGHT 128
in data file, the eyes disappear, only horizontal row are displayed....
I don't think changing the screen dimensions will have any effects on the size of the eyes
Ok, but now the eyes aren't in center, are on top. In bottom there are a lot of space
great video! thanks!
there is an X_offset function but not a Y_offset function. it would be nice to have the eyes in the middle of the screen. is that possible?
Thanks. I never tried to move the eyes, I am pretty sure it is possible
Where i can find that?
ok so ive built this but getting the following error message when i compile the code..
exit status 1
'NUM_EYES' was not declared in this scope
Anyone any ideas how to sort this??
Hi, can I use this display with a camera? I'm trying to made a digital nigth vision. Thank's
I am not sure, this could be complex because you would have to stream the video from the camera to the display through the ESP32. This is worth a try!
Excellent video. It worked perfectly. Thank you very much. One question is how can I get the eyes more centered onto the screen?
I have tried with no success!
Thank you for the response. I fumble around as well and had no luck. It's still an awesome project. @@thelastoutpostworkshop
I added a yposition to the eyeInfo_t typedef and duplicated a y for every x in config.h and eye_functions.ino and moved the eyes down about 40. I little bigger would be better but we might have to regen the images.
@@Ron_Rhodes can you share you updated code please?
really appreciated!
I'm currently mangling the code to try and make the joystickswork. @@hauntedgroundz1189
but try this:
Add Yposition
// This struct is populated in config.h
typedef struct { // Struct is defined before including config.h --
int8_t select; // pin numbers for each eye's screen select line
int8_t wink; // and wink button (or -1 if none) specified there,
uint8_t rotation; // also display rotation and the x offset
int16_t xposition; // position of eye on the screen
int16_t yposition; // position of eye on the screen
} eyeInfo_t;
in the main program.
... then in the config.h
#define EYE_1_YPOSITION 40 // y shift for eye 1 image on display
#define EYE_2_YPOSITION 40 // y shift for eye 2 image on display
...
and set with new arg ..
eyeInfo_t eyeInfo[] = {
{ TFT1_CS, LH_WINK_PIN, TFT_1_ROT, EYE_1_XPOSITION,EYE_1_YPOSITION }, // LEFT EYE chip select and wink pins, rotation and offset
{ TFT2_CS, RH_WINK_PIN, TFT_2_ROT, EYE_2_XPOSITION,EYE_2_YPOSITION }, // RIGHT EYE chip select and wink pins, rotation and offset
};
... in the eye functions code add line
eye[e].xposition = eyeInfo[e].xposition;
> eye[e].yposition = eyeInfo[e].yposition;
... and finally call the method adding ypos
tft.setAddrWindow(eye[e].xposition, eye[e].yposition, SCREEN_SIZE, SCREEN_SIZE);
hope this helps.
worked for me when i first tried now my display just turns on
how to increase eye size?
i need linke eye's video fur display
I had a problem with uploading the code, which I eventualy traced to the display's DC pin being connected to GPIO2 on the ESP32; a common problem apparently. I could upload the code with the DC disconnected and then by re-connecting DC and resetting the ESP32 the "eye" appeared on the display - not ideal. I then edited User_Setup.h file as follows to move the display pins to safer GPIOs.
On line 45 comment out (i.e. add “//” in front of the text) the line defining the ILI9341 driver.
On line 65 uncomment (i.e. remove the “//”) the line defining the GC9A01 driver.
On lines 212 through 218 comment out all the SPI definitions for the ILI9341.
On line 223 set MOSI to 23 //DIN
On line 224 set SCLK to 18 //CLK
On line 225 set CS to 22 //CS
On line 226 set DC to 16 //DC
On line 227 set RST to 4 //RST
In User_Setup_Select.h make sure that line 80 is commented out i.e. //#include // Setup file for ESP32 and GC9A01 SPI bus TFT 240x240
Otherwise the changes to User_Setup.h will be ignored and the display won't work.
I think another approach could be to edit Setup46_GC9A01_ESP32.h and change the GPIOs to the safe numbers shown above and then uncomment User_Setup_Select.h line 80i.e. #include
Hope this helps anyone having the same problem. Anyone using PlatformIO and an ESP-PROG JTAG programmer probably won't see this potential problem.
I have seen some screens with ESP32 board, its like one module. will this project on that screen??
which module ?

i have successfully uploaded but TFT does not light up
Double check your wiring, make sure the TFT receives power
Thank you very much for your help. After I checked, it was indeed the cable that was disconnected😊😊
Thank you. It turns out the cable was disconnected
Sorry, I want to ask, the eyes are too small, where can they be changed so that the eyes are a little bigger?

This error is raised by ESP32 core library when setting a value to the wrong pin, this is probably due to an error in your wiring
