Feather ESP32 V2 Neopixel not working, even factory reset

Post by jromang »

I have trouble with the Neopixel on the Feather ESP32 V2 ; every time I try to use it, the board hangs.
I even tried compiling the factory reset sketch from here : https://learn.adafruit.com/adafruit-esp ... tory-reset, and the program ends up with this error :

13:14:36.110 -> entry 0x400805e4

If I comment out all NeoPixel code, everything works perfectly (Wifi and I2C scanning).
If I download and use the binary factory reset file without compiling the sketch, everything works (even the NeoPixel color change)

Does anyone have an idea to resolve my problem ?

Try updating NeoPixel library to latest release. Probably related to this:
