Please document #define to identify MegaCoreX #145

technoblogy commented 2 years ago

Is there a #define that identifies that the MegaCoreX core is being used, and if so, could it be documented?

Something like #if defined(DXCORE) and #if defined(MEGATINYCORE) that Spence Konde provides for his cores?

It would be easier than doing:

#if defined(__AVR_ATmega808__) || defined(__AVR_ATmega1608__) || defined(__AVR_ATmega3208__) || \
defined(__AVR_ATmega4808__) || defined(__AVR_ATmega809__) || defined(__AVR_ATmega1609__) || \
defined(__AVR_ATmega3209__) || defined(__AVR_ATmega4809__)

Yes, there is. It's quite hidden, but it's there. I should probably document this. They are all located in the pins_arduino.h files.

Thanks! Exactly what I was looking for.
