The counter will count from 0 to 9 and will rollover. Each radio will * wait in receive mode for approximately one second. Upon receiving data, or * timeout of one second, the radio receive function will return. If valid data * was received, the radio's receiverOn() method will return the number of bytes * that were received. In this example, the data can be monitored on the serial * port (please refer to printTxData() and printRxData() functions). * * ---------------------------------------------------------------------------- * * This example assumes that two BoosterPacks will be used to showcase the * wireless radio communication functionality. This same code should be * programmed to both LaunchPad development kits. * * This BoosterPack relies on the SPI hardware peripheral and two additional * GPIO lines for SPI chip-select and GDO0 for packet handling. They use pins 18 * and 19 respectively. * * In the default configuration, this BoosterPack is not compatible with an * external crystal oscillator. This can be changed, if necessary, and would * require reconfiguration of the BoosterPack hardware and changes to the * AIR430BoostFCC library. Refer to the BoosterPack User's Manual if necessary. * * For complete information, please refer to the BoosterPack User's Manual available at: * https://www.anaren.com/air/cc110l-air-module-boosterpack-embedded-antenna-module-anaren * * To purchase the 430Boost-CC110L AIR module BoosterPack kit, please visit the TI eStore at: * https://estore.ti.com/430BOOST-CC110L-CC110L-RF-Module-BoosterPack-P2734.aspx */ // The AIR430BoostFCC library uses the SPI library internally.
