好牛逼的样子！！:tongue: :tongue:

谢谢大家的回复 楼主已经找到问题了 是没有对io口进行操作 因楼主刚刚接触dsp还是新手 还望大家日后多多提携

下面的是Ti给的例程，我试过好几个例程都是这三个灯常亮。。。 void main(void) {    InitSysCtrl();    DINT;    InitPieCtrl();   IER = 0x0000;    IFR = 0x0000;    InitPieVectTable();    EALLOW;  // This is needed to write to EALLOW protected registers    PieVectTable.TINT0 = &cpu_timer0_isr;    EDIS;    // This is needed to disable write to EALLOW protected registers    InitCpuTimers();   // For this example, only initialize the Cpu Timers    ConfigCpuTimer(&CpuTimer0, 60, 500000);    CpuTimer0Regs.TCR.all = 0x4001; // Use write-only instruction to set TSS bit = 0    EALLOW;    GpioCtrlRegs.GPBMUX1.bit.GPIO34 = 0;    GpioCtrlRegs.GPBDIR.bit.GPIO34 = 1;    EDIS;    IER |= M_INT1;    PieCtrlRegs.PIEIER1.bit.INTx7 = 1;    EINT;   // Enable Global interrupt INTM    ERTM;   // Enable Global realtime interrupt DBGM    for(;;); } [ 本帖最后由 zhengyooki 于 2013-10-13 10:52 编辑 ]
