我帮你写了一个秒表的程序，估计LCD1602时序时间跟不上，写了用5位LED显示的程序，给你参考：
 程序代码：#include"STC12C5A60S2.H" sbit DIG_0=P2^0; sbit DIG_1=P2^1; sbit DIG_2=P2^2; sbit DIG_3=P2^3; sbit DIG_4=P2^4; bit Flag_Run; unsigned char code LED[10]= { 0xC0,0xF9,0xA4,0xB0,0x99, 0x92,0x82,0xF8,0x80,0x90 }; void Init_Timer(); void Init_INT(); void PRI_Seting(); void main() { Init_Timer(); Init_INT(); PRI_Seting(); while(1); } void Init_Timer() { TMOD=0x02; TH0=TL0=256-200; //定时0.2mS TR0=1; ET0=1; } void Init_INT() { EX0=1; EX1=1; EA=1; } void PRI_Seting() { IPH=0x02; //优先级设置：T0>INT0>INT1 IP=0x01; } void Run_Timer() interrupt 1 { static unsigned char i=0; static unsigned int t=0; if(Flag_Run==1) { i++; if(i>=5) { i=0; t++; } } if(t>=60000) { t=0; P2=0xFF; switch(i) { case 0:P0=LED[t%10];DIG_0=0;break; case 1:P0=LED[t/10%10];DIG_1=0;break; case 2:P0=LED[t/100%10];DIG_2=0;break; case 3:P0=LED[t/1000%10];DIG_3=0;break; case 4:P0=LED[t/10000%10];DIG_4=0;break; default:break; } } } void Sotp() interrupt 0 { Flag_Run=0; } void Run() interrupt 2 { Flag_Run=1; } |
