[Lilygo TTGO T8 ESP32-S2] Hello, World?

Other Hardware 3rd Party Boards
1

Hello,

Newbie question.

To check that the controller works, I'd like to run a Hello World on that device.

  1. Do you confirm the current stable release of the Arduino IDE doesn't support it, and I must use the RC instead?

  2. Would somone have a Hello World for it?

Thank you.

Does this work: TTGO-T-Display/TFT_eSPI/examples at master · Xinyuan-LilyGO/TTGO-T-Display · GitHub
Or this: https://github.com/Xinyuan-LilyGO/T-Display-S3/tree/main/example/arduino

Thanks.

After adding the URL for that board through Arduino's File > Preferences, selecting the COM port, and installing Bodmer's TFT_eSPI, I compiled and uploaded Bodmer's Smooth_Graphics_Demo.ino.

Once done, Arduino says "Hard resetting via the RTS pin…", but nothing happens.

Hitting the RST button: Nothing.

Unplugging, replugging the USB cable: Nothing.

The screen remains dark.

Maybe Arduino doesn't really support that controller? Or could it have something to do with Brodmer's TFT_eSPI?

Edit: The following code works, so at least the board works…

void setup() 
{ 
	Serial.begin(9600); 
	Serial.println("In setup"); 
} 
  
void loop() 
{
	Serial.println("In loop"); 
	delay(500);
}

… but the screen is still dark when trying \examples from the eTFT_SPI library and rebooting:

}

Edit: It looks like I'm not the only one:
