I'm planning to use nRF24L01-transmitters together with a SD-Card on an arduino mega. Both will use the SPI interface, so I'll need to toggle the CS pin(s). I will use the RF24 libary and I don't want to change the source code of it ().
Because of other limitations on my self-made-shield I have to use the analog pins of the Mega to control the chip-select and chip-enable functions. Its written here that I can "use any available pins": https://tmrh20.github.io/RF24/Arduino.html
My question now: Is that also true for analog pins? Can I just use the number of the analog pins (55,56...) of the mega for it?
Thanks a lot in advance and all the best Tim
