uj5u.com熱心網友回復：
要使用狀態機來撰寫，另外狀態機之間需要預留足夠的等待報文和分析報文的時間。另外有的芯片剛剛上電，需要等待10多秒才允許發送指令，這些情況都需要考慮。
uint8_t isr = 0 ; //狀態機
uint8_t 50ms_mark = false;//50ms標識，注：在定時中斷每隔50ms置標識
1、發送指令
if (50ms_mark)
{
switch (isr)
{
case 0:
發送指令1
break;
case 1:
發送指令2
break;
}
2、決議報文
if (收到串口資料）
｛
switch (isr)
{
case 0:
if (指令1回復正確）
isr=1;
break;
case 1:
if (指令2回復正確）
isr=0
break;
}
｝
