ESP32 C3 Compiling is not possible

Hi Ben

C3 Compiling is not possible (or not anymore).
I have tried different python and ESP-idf versions. ESP32 S3 always works ESP C3 never.

Hi Stefan,

Thanks for letting us know, looks like it's the I/O optimisation isn't working for the C3 for whatever reason.

e.g. GPIO.out_w1ts = Mask;

I'll investigate and see if I can make it work, might be we turn off the optimisation for the C3 and instead use the recommended (but slow) I/O layer.

Hopefully resolved for you now via library updates.
