單片機定時器0與定時器1沖突

ID:652483 · 發表于 2021-4-21 01:53

我用單片機定時器0作為LCD串行顯示，能正常顯示，但是加入定時器1作為波特率發生器后，LCD就不能顯示了，這是由于定時器優先級的問題呢，還是主函數邏輯錯誤，WiFi模塊這樣寫是不是有問題，各位大佬幫忙看一下。

單片機源程序如下:

sbit beep = P2^0;//蜂鳴器
sbit setKey = P3^3;//按鍵
sbit addKey = P3^4;//
sbit subKey = P3^5;//
sbit paishui = P3^6;//排水---低電平觸發
sbit jiashui = P3^7;//加水
long s,W;
uchar table[40];//用于接收wifi模塊反饋到MCU上的數據
uchar code ta[]="0123456789- "; //測試一下
uchar table[]="溫度：00.0 C";//傳送用定位模
uchar Receive,i,xm1,xm2,xm3,xm0;
uint tvalue;//定義一個全局變量，用來合高低8位溫度//顯示溫度
float dataV[4]= {0};
unsigned char dataTH[8]={110,30, 99, 30, 8,2, 45, 15};
unsigned char lcd[8] = {0};
void alarm();

我只看到了串口中斷函數，定時器0，確定有函數響應并且開啟了？
