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!
