Hi, I tried to use pin 8 as an input. It worked well, as long as I didn't start any SPI-communication. From that moment on, all I ever got, was a high on that input. I measured 1.635V which made me think that it could be the mean of normal SPI chattering (0 V - 3.3 V).
On the pin out card, pin 8 has a grayed out DIN noted and I read in the forum somewhere, that this was an alternative pin for MISO.
Could this really have been SPI that messed up my readings? I used SPI on it's «normal» pins (10, 11, 12, 13).
Is it possible to use pin 8 alongside SPI? How would I do that?
Thank you, Dani
