2 years ago It looks like FastLED doesn't support ATmega324PB out of the box.
What happens if you replace the following line with this? https://github.com/FastLED/FastLED/blob/b5874b588ade1d2639925e4e9719fa7d3c9d9e94/src/platforms/avr/fastpin_avr.h#L274

Hi I'm trying to use a Mrga324PB with FastLed library to control a WS2811 chip. I'm having an erro "Invalid pin specified" even if I use the default pin 5. Tried other pins, same error.
Apparently the library checks if pin can be used, and expects some return.. Is there a workaround?
Thanks and sorry for the trouble.
