用TIMER0定波形的周期(高电平时间+低电平时间),用TIMER1定高电平的时间,用中断方式,帮我看看程序那里有问题?
波形从P1.7输出.
#include<reg52.h>
#define uint unsigned int
sbit P1_7=P1^7;
uint count0;
uint count1;
void inter0()interrupt 1 /*timer0*/
{
count0++;
if(count0==10000)
{
P1_7=1;
TR1=1;
}
TR0=1;
}
void inter1()interrupt 3 /*timer1*/
{
count1++;
if(count1==5000)
{
P1_7=0;
}
TR1=1;
}
void main()
{
TMOD=0X22;
TR0=1;
TR1=0;
EA=1;
ET1=1;
ET0=1;
TH1=-1000/256;
TL1=-1000%256;
TH0=-1000/256;
TL0=-1000%256;
P1_7=0;
while(1);
