ATmega328PB and port PC2 problem about minicore

[MCUdude]

That's because PIN_PC2 is defined as 16:

MiniCore/avr/variants/standard/pins_arduino.h

Line 172 in 0bb50f6

#define PIN_PC2 16 // A2

Instead of Serial.println(Motion); you should do Serial.println(digitalRead(Motion)); instead.

Thanks!

Sorry, to come back to this!
What are the reasons that you should use digitalread here? Normally this isn't necessary, is it?
Is this due to the type of bootloader?

[MCUdude]

Because Serial.println(Motion); will only print the value Motion holds (16), while Serial.println(digitalRead(Motion)); will read the value of pin Motion (16). This isn't MiniCore spesific, but applies for all Arduino boards.

Thanks for your explanation. Learned something again!
