问 我用EASYARM2210开发板上的UCOS代码，一进T1中断就死机，大家帮忙看看
void __irq  IRQ_Time1(void)
{    
    uint8 i,j;
    fp32 f;     
    
    T1IR = 0x01;                                            //清除中断标志        
    OSIntEnter();      
    if(Motor0Struct.uiMoveSteps)
    {
        Motor0Struct.uiMoveSteps--;
        if(Motor0Struct.ucMoveDirection)
        {
            Motor0Struct.ucState++;
        }
        else
        {
            Motor0Struct.ucState--;            
        }
        Motor0Struct.ucState %= 4*(Motor0Struct.ucNumOfMicroStep+1);
        f = cos(Motor0Struct.ucState*PI/(2*(Motor0Struct.ucNumOfMicroStep+1)));
        i = (uint8)(0x7f*fabs(f));
        if(f < 0)
        {
            i |= 0x80;
        }
        f = sin(Motor0Struct.ucState*PI/(2*(Motor0Struct.ucNumOfMicroStep+1)));
        j = (uint8)(0x7f*fabs(f));
        if(f < 0)
        {
            j |= 0x80;
        }
        MotorDriverDAWrite(0x08,i);
        MotorDriverDAWrite(0x09,j);
    }    
    VICVectAddr = 0x00;                                        //通知VIC中断处理结束
    OSIntExit();        
}
答 1: 可能是你没用 IRQ_HANDER 这个句柄！！！这个句柄在 IRQ.S里边定义：比如：“IRQ_Handler HANDLER IRQ_Exception”这可以帮你保存现场。
