Find a replacement ESP32-wroom #54

Open unglazedstamp opened 1 month ago

This afternoon, after some wiring changes, the ESP32 stopped to work correctly. The board is still recognized by my computer but I'm not able to flash it with the arduino ide. I tried with other computers without success. The most probable issue is a short circuit that broke some of the components, but I don't see any visible damage. I checked the power supply and it still provides the same 5v as before to the board. I tried to reset and checked the troubleshoot documentation (https://docs.espressif.com/projects/esptool/en/latest/esp32/troubleshooting.html) but without success. The error is "No serial data received." Could we have another ESP-32 wroom board as soon as possible and some advice on how to avoid such event in the future please ? @feeds @malenraychev

Did you manage to get one of the other ones running in the end? Or do you actually need to find a replacement? @unglazedstamp

If not I will ask Christoph what he can do to help find something that works.

The replacement ESP you gave me was a ESP 8266, so it was incompatible with the libraries I used. Lucas gave me an ESP 32 C6 which was compatible with all the libraries except the one for the servo. After a while I managed to replace the library with a low level control of of the pins. The changes are on the PR: #48 . Thank you for your help.
