Open either the simple example or feature demo project for PIC18.
From the project window, choose to edit file "ConfigApp.h" under the directory "Header Files -> Application", as shown below.
In file "ConfigApp.h", first elect to use MiWi P2P protocol, make sure to uncomment "#define PROTOCOL_PRO" and comment out "#define PROTOCOL_MIWI" and "#define PROTOCOL_P2P".
Second step, choose the RF transceiver to be used. Only MRF24J40 is supported for this demo board. Uncomment "#define MRF24J40" and comment out all other transceiver definition.
From the project window, choose to edit file "HardwareProfile.h" under the directory "Header Files -> Application", as shown below
In the file "HardwareProfile.h", choose the PICDEM Z board by uncomment "#define PICDEMZ" and comment out all other demo boards definitions.
Remove any linker script in the project, as shown below.
