Please help!
I have ESP32-S3 UNO development board. I try to use RM68140 TFT screen to mount it as shield.
Using TFT_eSPI library. Modified files User_Setup.h and User_Setup_Select.h to enable RM68140.
Unfortunatley it does not work and crashes on
tft.init();
I also tried TFT ILI9341 - the same result.
If I use Arduino UNO R4 both Minima and WiFi, it works nicely.
Thanks!
Read the pinned post re 'How to get the most from the forum'
Keep in mind we can not see what is in front of you.
Try this fork, it has your display.
PS Also original TFT_eSPI
Just of of curiosity, do you have a link? I've never heard of it.
Show your User_Setup.h file.
Thanks. Unfortunately it does not compile for me:
error: 'LCD_DC' was not declared in this scope
7 | #define TFT_DC LCD_DC // Data Command control pin
RM68140 is included in TFT_eSPI, but it does not help.
I did not find examples when screen was used as shield for ESP32-S3 UNO.
There are only examples connecting screen by wires.
In original Arduino UNO screen works just fine.
What board do you choose in IDE?
ESP32S3 Dev Module
Do you have a pinout of your board?
Hi @kvyaznikov. This is a well known problem that occurs when using the combination of the "TFT_eSPI" library, the ESP32-S3 board, and a recent version of the "esp32" boards platform that adds support to Arduino IDE for the ESP32-S3-based boards like your "ESP32-S3 UNO development board".
I provided a list of relevant discussions here:
I think if you take a look through those, you will find several alternative solutions to the problem. Or perhaps one of the forum helpers who are experienced with this problem will provide advice on a specific solution.
Sorry for being late.
Here it is:
// USER DEFINED SETTINGS
// Set driver type, fonts to be loaded, pins used and SPI control method etc.

// setups and then easily select which setup file is used by the compiler.

Thanks. Unfortunately no go. More over it starts to crash.
My board is ESP32-S3 UNO or ESP32-S3 D1. It is ESP32-S3 but in form factor of UNO. So I could put TFT display as shield - no wires.
If I use board version 2.0.14, it does not crash, but nothing on screen.
If I ugrade version to 3.3.2, last one, it starts to crash.

And if Core 3.2.0
C:\Users\YOUNAME\AppData\Local\Arduino15\packages\esp32\hardware\esp32\3.2.0\variants\esp32s3
IDE 2.3.6
Core: 3.3.2, but location is the same.
Unfortunately still white screen, despite attempts to draw some. I tried to screw "pins_arduino.h" in order to be sure that's the file in use.
I checked screen on native Arduino UNO - it works.

TFT_eSPI tft = TFT_eSPI();
setup_t user;
void setup(void) {
Serial.begin(115200);
while(!Serial);
Serial.println("Setup started");
tft.init();
tft.setRotation(0);
tft.fillScreen(TFT_BLUE);
tft.drawRect(0, 0, tft.width(), tft.height(), TFT_GREEN);
