不是说中断函数越短越好吗？是把串口发送那几条语句放到定时器中断里吗？我的主要问题是串口中断函数感觉都没执行~·能帮我看下吗？非常感谢~~这个程序我都调试了半个月了，唉！~~:Sad:

功能就是把超声波测距的值（程序中的S）通过串口发送给组态王显示~~~求大神帮助~~ #include #include #define uchar unsigned char #define uint unsigned int //#define N 800 sbit SDATA_595 = P2^5; //串行移位输入 sbit SHcp_595 = P2^7; //移位寄存器时钟输入SHcp sbit STcp_595 = P2^6;   //存储寄存器时钟输入STcp sbit fengmingqi=P2^0; unsigned int  time=0; unsigned int  timer=0; unsigned int  t=0; unsigned char posit=0; unsigned long S=0; bit      flag =0; unsigned char const discode[] ={0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,0x80,0x90,0xBF,0xff/*-*/}; unsigned char const positon[3]={0x10,0x08,0x04}; unsigned char disbuff[4]={0,0,0,0,}; sbit  RX=P1^2; sbit  TX=P1^3; sbit  Q1=P1^4; sbit  Q2=P1^0; sbit  Q3=P1^1; sbit  K1=P1^7; sbit  K2=P1^6; sbit  K3=P1^5; sbit  K4=P2^1; sbit  S1=P2^2; sbit  S2=P2^3; unsigned char rec[50]; unsigned char code error[]={0x40,0x30,0x46,0x2a,0x2a,0x37,0x36,0x0d}; unsigned char send[]={0x40,0x30,0x46,0x30,0x31,0x00,0x00,0x00,0x00,0x0d}; unsigned char i; unsigned char ath(unsigned char,unsigned char); unsigned int hta(unsigned char); void uart(void); //void delay(uint); /*-----------延时子程序--------- void delay(uint z) {         uint a;         for(;z>0;z--)         for(a=100;a>0;a--); } */   void OUT_595(void) {         STcp_595 = 0;         _nop_();         _nop_();         STcp_595=1; //上升沿将数据送到输出锁存器         _nop_();         _nop_();         STcp_595 = 0 ; } void WR_595(uchar x) {         uchar temp;         uchar j;         temp = x;         SHcp_595 = 0;         for (j=0; j
