要使用状态机来编写，另外状态机之间需要预留足够的等待报文和分析报文的时间。 另外有的芯片刚刚上电，需要等待10多秒才允许发送指令，这些情况都需要考虑。 uint8_t isr = 0 ; //状态机 uint8_t 50ms_mark = false;//50ms标识，注：在定时中断每隔50ms置标识 1、发送指令 if (50ms_mark) { switch (isr) { case 0: 发送指令1 break; case 1: 发送指令2 break; } 2、解析报文 if (收到串口数据） ｛ switch (isr) { case 0: if (指令1回复正确） isr=1; break; case 1: if (指令2回复正确） isr=0 break; } ｝
