hi all
I'm using arduino pro mini with nrf24l01 and mcp4131 digital pot. To control mcp I'm using SPI with the following pins SCK digital Pin 13 SDI/SDO digital pin 11 and CS on Pin 5. Also my connection for nrf24l01 is
CE PIN 9
SCN PIN 10
SCK PIN 13
MOSI 11
MISO 12
The problem is that digital pot seems to take wrong values because of nfr. I have read some articles about spi that I need to change some pins to connect more than on device but I can't understand exactly how to do it could anyone help me?
Thanks
