This library is designed to interface an Amicom A7106 2.4G FSK/GFSK Transceiver with a Rasberry Pi. These are very cheap radios that we found in used E-Ink tags.
Connect the RST pin to GND so that the MSP430 stays in reset the whole time.
Connect a jumper to the VCC pin to supply 3.3V.
Solder jumpers to the six test pads.
Connect the radio to the Pi using the RX pins. If you have two radios for transceiver testing, connect the second to the TX pins.
