void ad_con(void)
{
unsigned int acbuf;
unsigned long acbuf0;
if(ADCON0bits.GO==0)
{
acbuf=ADRES;
if(acbuf<ZERO_SPEED_REF)
{
DesiredSpeed=0;
}
else if(acbuf<LOW_SPEED_REF)
{
DesiredSpeed=LOW_SPEED;
}
else
{
acbuf0=HIGH_SPEED-LOW_SPEED;//*(acbuf-LOW_SPEED_REF);)/(1023-LOW_SPEED_REF);
acbuf0*=(acbuf-LOW_SPEED_REF);
DesiredSpeed=(unsigned int)(acbuf0/(1023-LOW_SPEED_REF))+LOW_SPEED;
}
ADCON0bits.GO=1;
}
}
问题：用ICD2仿真时，把断点设置在ADCON0bits.GO=1;这里，发现始终不会停止，后经检查发现是因为DesiredSpeed这句进入之后就出不来了！点击程序暂停，发现程序复位了！！望各位老大给看看！！谢谢！！！芯片：PIC18F2431
