I've recently moved from the PIC microcontroller to the Arduino for a project and have chosen the Pro Micro found here http://www.sparkfun.com/products/11098 and the RFM22B found here http://www.sparkfun.com/products/10154 and have been trying to implement the library from http://www.open.com.au/mikem/arduino/RF22/.  I haven't had any luck with trying to get it to work with this library at all.  Even just trying to read the temperature from the module doesn't work but if I write up my own function to read the temp I get readings.  The readings I get aren't correct but I get something.

RF22B           Arduino
GND-----------GND
3.3v-----------PIN2 set to OUTPUT and HIGH
CSN---VD-----PIN10  VD = Voltage Divider R1 = 1.8K and R2 = 3.3K
SCK---VD-----PIN15
SDI----VD-----PIN16
SDO-----------PIN14  No voltage divider!
GPIO---\
Tx-----/
GPI1---\
Rx-----/

The only difference from my code and the one from the library is in the setup I have pinMode(2,OUTPUT) and digitalWrite(2,HIGH).
Thanks for the help!
