From what I can gather it uses a serial connection - so have a look at serial examples for PBP and then adapt them to send the instructions to the device. There is an example here http://support.iteadstudio.com/suppo...cs/11000012477 where someone is using an arduino without any library files, which may help

You should be able to used hserout command with a PIC that has a UART serial port (most do)
