#define uint unsigned int

void ISR_Timer3 (void);
void init_devices(void);

void main(void)
{init_devices()；｝

void init_devices()
{EA=0;
Time3_init();

}

void Time3_init (void)
{T3CON=0x90;

if(Cycle_dat<0xfe){Cycle_dat++;}else{Input_AcValue=0;}
if(delay_us_timer!=0)delay_us_timer--;//
if(OnInvDelay!=0){OnInvDelay--;}
//off_RedLED;//
if(sys==bat_work||sys==Test)
{

         if(OnInvDelay==0)
            {if(PWMflag==0){run_pwm0();}
      if(PWMflag==1){run_pwmx();}
      if(PWMflag==2){run_pwm1();}
      if(PWMflag==3){run_pwmx();} }

      }
   else{close_PWM();}
  }

我是新手，不知道错在哪了，就是不进入定时器3，望高手指教
还是那里设置有问题啊

因为你没有开启TIMER3对于的中断使能控制位，IEN1的第四位ET3，在EA=1那句的前面加入“IEN1 = Bin(00010000); ”就可以了。

我已经是这样设置的了，可是就是不进入定时器啊。

问问高手问题在哪里了

额，学习中

应该是MCU自己复位了，还没到1秒就再次初始化了TIMER3

只看该作者 · 2011-3-10 08:18

我仿真的时候。设置断点在定时器那就是没进去过

只看该作者 · 2011-3-10 08:23

难道这款芯片的定时器还有什么特殊的设置吗

只看该作者 · 2011-3-10 09:18

没有什么特殊的，应该还是你的程序不对。
如果不介意的话，把你的程序源文件发出来，让我们看看。
也可能如7楼的大侠所说是复位了，如果你开启了看门狗，而且设置的WDT时间小于1秒就会出现复位，因为你在main主程序中没有做清看门狗的动作。

只看该作者 · 2011-3-10 09:26

哦！但是我还没启用WDT功能啊，没设置看门狗啊！

由于timer3控制寄存器在bank1，所以在写之前要置bank,昨天我也没有发现，不好意思。

一下的程序我调试过，可以运行。
#include<SH79F166.h>
#include<intrins.H>
#define uchar unsigned char
#define uint unsigned int

void init_devices(void);
void Time3_init (void);
void ISR_Timer3(void);

void main(void)
{
init_devices();
while(1); //程序不能?行?束。
}

void init_devices()
{EA=0;
Time3_init();
CLKCON=0x00;  //
//PWM10ms_data=PWM10ms;
IEN1 = 0x10; // 打?Timer3中?
EA=1;

}

void Time3_init (void)
{
INSCON = 0x40;
T3CON=0x00;
TL3=0x96;
TH3=0xFF;
TR3=1;
INSCON = 0x00;
}

void ISR_Timer3(void) interrupt 11 //中???需要采用??字，中?地址在0x5B
  {
//if(in_AC_cycle!=0)in_AC_cycle--;
//if(Cycle_dat<0xfe){Cycle_dat++;}else{Input_AcValue=0;}
//if(delay_us_timer!=0)delay_us_timer--;//
//if(OnInvDelay!=0){OnInvDelay--;}
//off_RedLED;//
//if(sys==bat_work||sys==Test)
// {
//
//          if(OnInvDelay==0)
//             {if(PWMflag==0){run_pwm0();}
//       if(PWMflag==1){run_pwmx();}
//       if(PWMflag==2){run_pwm1();}
//       if(PWMflag==3){run_pwmx();} }
//
//       }
//    else{close_PWM();}
if(ACC == 0);

  }
