元旦放假，急于赶一个小项目，做了一个M0516LAN驱动SIM900A的测试。第一次用SIM900A，其中遇到几个小问题，调了好久，也问过群里用过SIM900A的几位朋友才调通，在此感谢。最弱智的问题是我把NRESET接到了PWM3上，然后又启动了PWM3，虽然后面把P43置成IO输出却不成功，然后大半晚上就那么悲剧掉了。新唐的库是置成了复用功能再想置回IO，需要先DrvGPIO_InitFunction(E_FUNC_GPIO);才能配置IO功能的。我后来还是不启动PWM就通过了开机过程。只要SIM900A开机了，NETLIGHT的LED就会闪烁，不管有没有SIM卡。另外，所有SIM900A的AT命令都是以“\r”结束的。
“sim900a.c ”文件源码如下：
