Hallo,
ich wollte die LED M1_DuoLED_Schleife1_Rot ansprechen. Diese wurde aber auf A6 gelegt. A6 und A7 können scheinbar nur als Analog In verwendet werden.
Analog pins A6 and A7 are weird. They can *only* be used for analogRead() - there aren't any registers to write to for them like there are for other pins. I get the impression they were an afterthought (maybe the DIP package was released first, then they're like "hey we have some extra pins on TQFP32, let's connect them to the unused channels on the ADC mux")...
