Programming RFM radio modules in Basic

[richard]

. I need first, to understand how to use the SPI interface

not really you need to understand what the rmf69 module wants , not what the pic mssp module is capable of .

refer to the rfm69hw data sheet , they do provide a pic connection example .

I have chosen the least complicated scheme possible

don't forget its a 3.3 v device , logic level converters are needed for a 5v pic
