ESP32 stopped working after after code upload

Using Arduino Microcontrollers

Hello everyone,

I've been working on an ESP32 project for a while and everything was working fine, using a round LCD display :

I am using these ESP32:

Everything was working as expected, but then all of a sudden when I upload my code, nothing executes on the ESP32. Upload goes fine without any error/warning. Serial monitor is empty (while I previously did get my debug lines there).

Interestingly, now both red an blue LEDs are on on the board, while previously when the code was running fine, I only had the red (power) LED on.

I've tried coming back to a simpler code (blink), same behaviour : code uploads, but no execution. I've tried changing the ESP32 board, same behavior as well.
This is very weird as I did not change anything in my code or the upload procedure, yet I can't get the thing to work any longer 2mn later...

Would you have any idea / pointers?
Thank you in advance!

Try loading a simple LED blink program and then pressing the EN\Reset button.

Hi there,

I figured it out! My TFT-espi library had been updated, resetting my modifications in User_Setup.h.
Now back to normal! :+1:

I would like to run your code here on my ESP32 with a round display.
Can you post your code?

Hi @ruilviana ,
I'm using a slightly modified version of the example script provided with the tft_espi library, which you can find under file→examples→TFT_eSPI→Sprite→Animated Dial.
I can't recommend enough this video explaining how to get it to run on your ESP32 : https://youtu.be/k2c2zCmC_X0?t=1095
