This is a port of the RFM69 library for arduino from https://github.com/LowPowerLab/RFM69 to python for raspberry pi. Attach the RFM69 as follows:
RFM pin - Pi pin
3v3 - 17
DIO0 - 18 (GPIO24)
MOSI - 19
MISO - 21
CLK - 23
NSS - 24
Ground - 25

You can change the interrupt pin (GPIO24) in the class init.

prerequisites: RPi.GPIO and spidev

if you are using newer firmware you'll need to get a newer spidev, the old one is no longer working:

git clone https://github.com/Gadgetoid/py-spidev

cd py-spidev

sudo make install
