Description:

This project demonstrates the usage of the QFM-TRX1-24G 2.4Ghz TI CC2500 transceiver unit. With this demo application you can send data from one primer1 to another. It uses the Primer1 SPI1 port to communicate with the transceiver.

usage of GPIO for input/output configuration
usage of ISR for capture of GDO0 events
usage of SPI1 for transceiver communication

To send/receive data the following functions can be used:

void CC2500_SendPacket(u8 *txBuffer, u8 size) ;
u16 CC2500_ReceivePacket(u8 *rxBuffer, u8 *length);

Hardware interface using the Primer1 J1 connector:

The code provided in this project is for test purposes. I'm working on a better and more robust implementation
