大家好：
本人第一次使用HC908JK8MCU
经过多方面的学习，现在程序终于可以运行起来。
显示,AD采集，数据处理都没有问题了！
但是，一个最重要的问题一只困扰着我。
我使用了定时器淤出中断，可程序就是进不了中断处理程序！
采用USB-MON08 Rev D 进行在线调试！
我的程序如下：
void InitTimer(void) //初始化定时器1－－－晶振频率=8MHZ,总线频率=2MHZ,分频因子=64,预置值=1250,=40毫秒一次中断
{
T1SC=0b01100110; //01100110允许溢出中断、
//不启动计数、分频因子=64
T1CNTH=0; //计数器初值清0
T1CNTL=0;
T1MODH=0x02; //设20毫秒产生1次溢出中断
T1MODL=0x71; //模数寄存器设定值
//中断频率:2000000/64*625 = 50Hz
T1SC_TOF=0;
}
#pragma CODE_SEG NON_BANKED
#pragma TRAP_PROC
//*定时器20Ms中断一次*/
interrupt void Timer_ISR(void)
{
T1SC_TOF=0;
SecData++;
//秒，分，时，开始计时
TimBuf[0]++;
if(TimBuf[0]>=60)
{
TimBuf[0]=0;
if(TimBuf[1]>=60)
{
TimBuf[1]=0;
if(TimBuf[2]>=24)
{
TimBuf[2]=0;
}
}
}
}
#pragma CODE_SEG DEFAULT
void main(void)
{
DisableInterrupts; /* 关中断 */
InitMcu();
InitDataCmd();
EnableInterrupts; /* 开中断 */
for(;;)
{
//KeyParse();//-------------键盘采集
LcdBuf[0]=0x01;
LcdBuf[1]=0x00;
LcdBuf[2]=0x00;//状态显示
LcdBuf[3]=0x00;
LcdBuf[4]=0xAa;//状态显示
LcdBuf[5]=0x08;//状态显示
AdParse();//--------------
FridgeStCon();//----------
LcdShowCmd();//-----------
//__RESET_WATCHDOG();//-----feeds the dog
}
}
