Si4313 是 Silicon lab 最新的高灵敏（-118dBm）ISM接收芯片，支持GFSK, FSK和OOK，工作频率240–960 MHz。本例程基于Silicon lab 的演示程序“RKE_demo”，主要的改进有: 取消LCD和USART接口，只保留与接收芯片有关的部分 改进接收状态机逻辑,大大提过了可靠性,原演示程序经常丢包 适用于SI4311和SI4312芯片-Si4313 Silicon lab is the latest high sensitivity (-118dBm) ISM receiver chip, GFSK, FSK and OOK, operating frequency of 240-960 MHz. This routine is based on Silicon lab demonstration program " RKE_demo" , the main improvements are: the abolition of LCD and USART interfaces, retaining only the relevant part of the receiver chip　improve the receive state machine logic, greatly raised the reliability, the original demo program often packet loss　for SI4311 and SI4312 chip
