求大佬幫忙改一下這個程序，通過P3.3口的中斷輸入控制觸發的角度，然后通過內部定時器控制觸發信號做相應的移相然后輸出波形
單片機源程序如下:
#include "reg52.h"
#include"ADC0808.h"
#include "lcd.h"
#define uchar unsigned char
#define uint unsigned int
sbit VT1=P2^0;
sbit VT2=P2^1;
sbit VT3=P2^2;
sbit VT4=P2^3;
sbit VT5=P2^4;
sbit VT6=P2^5;
uchar count;
uchar AD_num,angle_num;//采樣AD的值和導通的角度
uchar AD_signal,achieve_signal;
uint delay_num=0;//延時的時間
void Delay10ms() //@121MHz
{
unsigned char i, j, k;
_nop_();
_nop_();
i = 5;
j = 154;
k = 1;
do
{
do
{
while (--k);
} while (--j);
} while (--i);
}
void SCRTrg(uchar Num) // 脈沖寬度30°
{
switch(Num) // 觸發相位
{
case 1:
VT1 = 1; // 開通
VT6 = 0;
break;
case 2:
VT1 = 1; // 關斷
VT6 = 0;
break;
case 3:
VT2 = 0;
VT1 = 1;
break;
case 4:
VT1 = 1;
VT2 = 0;
break;
case 5:
VT3 = 0;
VT2 = 0;
break;
case 6:
VT3 = 0;
VT2 = 0;
break;
case 7:
VT3 = 0;
VT4 = 0;
break;
case 8:
VT3 = 0;
VT4 = 0;
break;
case 9:
VT5 = 1;
VT4 = 1;
break;
case 10:
VT5 = 0;
VT4 = 0;
break;
case 11:
VT5 = 0;
VT6 = 0;
break;
case 12:
VT5 = 0;
VT6 = 0;
break;
default:
break;
}
}
