非常感谢您的答复， 但是我用那你的外设CMD文件，编译出错呢。似乎外设分配的地址空间用问题呢

Eric,你好，我用你的推荐的工程例子中的文件，程序依然没有运行，还麻烦你再帮我看下程序。谢谢

试着能输出高低电平测试，但是有个疑问，系统时钟怎么去配置的，看那个初始化系统InitSysCtrl();
void InitSysCtrl(void){
// Disable the watchdog DisableDog();
// Initialize the PLL control: PLLCR and CLKINDIV // DSP28_PLLCR and DSP28_CLKINDIV are defined in DSP280x_Examples.h InitPll(DSP28_PLLCR,DSP28_CLKINDIV);
// Initialize the peripheral clocks InitPeripheralClocks();}
这个函数，里面似乎没有看是用CLKIN引脚输入的还是 X1，X2引脚输入的时钟。我按照例子中的_CPU_TIMER去执行，发现定时器没有运行。目前我的板子实际是用X1 X2 20M的晶振。想配置成100M，配置
/*—————————————————————————– Specify the PLL control register (PLLCR) and clock in divide (CLKINDIV) value.
if CLKINDIV = 0: SYSCLKOUT = (OSCCLK * PLLCR)/2 if CLKINDIV = 1: SYSCLKOUT = (OSCCLK * PLLCR)—————————————————————————–*/
#define DSP28_CLKINDIV 0 //
#define DSP28_PLLCR 10
定时器初始化函数
void InitSystemTimer0(){ unsigned char i; //SystemTimeTick=0; for(i=0;i<DELAY_TIMER_COUNT;i++) { DelayTimerParam[i]=0xff; } InitCpuTimer0(); ConfigCpuTimer(&CpuTimer0, 100, 1000);//cpu 100M 100us period CpuTimer0Regs.TCR.all = 0x4001; // Use write-only instruction to set TSS bit = 0 StartCpuTimer0(); IER |= M_INT1; // Enable CPU int1 which is connected to CPU-Timer 0 PieCtrlRegs.PIEIER1.bit.INTx7 = 1; // Enable TINT0 in the PIE: Group 1 interrupt 7
/****************************定时器配置***************************/
