背景
cc1101模块给的是stm8的例程，工作用不上，要用stm32的，所以要做移植；该模块使用的是spi通信，所以需要配置一下stm32的spi1来进行使用；
stm32 SPI1
我使用的是SPI1，配置如下，不同型号，配成不同的脚位就可以了；
SPI1的读写：

个人感觉cc1101的坑在于配置初始化的参数，虽然说可以使用smartRF来进行生成，但是这个过程会产生很多问题，假如我要用ASK调通了，但是我换成GFSK发现不行；这个初始化的配置寄存器我没有深究，反正你看了初始化代码和发送接收代码和我的差不多，但是就是不通的话，大多数就是初始化的时候寄存器配置有问题。下面共享一下代码，我就不放GitHub，感觉嵌入式没什么人用GitHub，Linux和前端，服务端用得比较多：
