PIN 12 broken .... Could I use another pin instead?
unfortunately some PINs on one of my arduinos are broken - due to beginners soldering. (A0, A6, A7, D12) (after unsoldering for the 5th time, there were some issues).
So is there maybe a way to use instead of PIN 12 for the radio e.g. PIN 8?
I already had a look at SoftSPI, but then I would need to use A0 which is broken as well.
For soft SPI, there are no constraints. You should be able to pick any pin you want. Just replace the pin assignments in RF24_config.h (assuming you run on the master branch):
const uint8_t SOFT_SPI_MISO_PIN = 16; const uint8_t SOFT_SPI_MOSI_PIN = 15; const uint8_t SOFT_SPI_SCK_PIN = 14;
