As an after thought, I decided to try and incorporate an NRF24L01 radio module into an exiting mega project. At present, almost all the pins from 13 down have been used. I know I can use 50, 52 and 52 for MISO, MOSI, and SCK respectively.
Most of the examples I am seeing are using the 8, 9 and 10 for the IRQ, CE and CSN respectively. Can I use other pins for for the IRQ, CE and CSN, and if so, are there constraints I need to be aware of. I was thinking maybe 47, 48 and 49 just to keep it in the same area as the others.
Any concerns I should be aware of?
