The SPI-based CyFi™ Transceiver (CYFISPI) User Module is a firmware interface to the CyFi radio modem hardware. The CYFISPI User Module API provides functions callable from both C and assembly to start the radio, send and receive data, change channels, transmit power, pseudo-noise codes, and more. Refer to the corresponding CyFi radio datasheet for detailed descriptions of the radio features. The CYFISPI User Module employs the SPI block as an SPI master to communicate with the CyFi radio transceiver.
