Using the hardware with MySensors

In order to use the hardware with MySensors, you need to change two pin numbers in MyConfig.h, which is located in your libraries directory. These are the right numbers: 

#define MY_RF24_CE_PIN 8
#define MY_RF24_CS_PIN 7

This needs to go before: 

#include <MySensors.h>
