Hello.
I have a single Arduino UNO board, and need to connect an LCD screen (16x2) and a nrf8001 BLuetooth breakout board.
To make sure I have available pins, I have connected a switch register, and have managed to get the LCD to work only using 3 digital pins on the Arduino. The code that I have for the nrf8001 allows me to change REQ, RDY and RST and use whichever pins I want, but CLK, MISO and MOSI pins seem to be hardcoded (somewhere).
Is it possible to configure these to use different digital pins?
Thanks.
