在CC1101通讯的时候主要值得注意的，1、SPI的底层是个基础，包括单片机带的SPI接口也好，自己用IO口实现也好，怎么来实现和硬件之间的链接了。2、编程实现的时候注意时序问题。。SPI的时序都一样，但是操作芯片的时候可能有应答，可能没有应答。。3、花最大功夫研究里面的寄存器的配置。整个通讯成功与否，通讯效果好不好都在寄存器的配置上。。个人认为必须理解各个寄存器的作用及使用的目的及意义了。。4、GDO0等IO口的配置在整个系统中的运用非常重要。常见配置值0x01,0x02,0x03,0x06,0x07，其中配置值最为常用配置0x06了，但是了，对于各种需求可以相应修改了，具体手册上写的比较明白。。
以下为2个CC1101和一个MSP430F5438的一发一收通讯测试程序，实验证明通讯效果比，MC31213（xbee），2401AG,24L01都强，表现在1、通讯视距中有障碍物（如一般水泥墙壁）不影响通讯；2、整个系统电流消耗比较小大约电流在10D多个ma。具体代码如下。
