标题: 关于激光分时发射问题就高手解决
为什么我的激光分时加了总线时钟初始化就不工作了
unsigned char Data[15]={0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0A,0x0B,0x0C,0x0D,0x0E,0x0F};
void Delay(unsigned int Time)
{
unsigned char i;
      DDRA=0xFF;
for(i=0; i<160; i++)
for( ; Time>0; Time--);
}
void liushui(void)
{
unsigned char i;

for(i=0;i<15;i++)
  {
  PORTA=Data[i];
  Delay(50);    //500us延时    50
  }
}  void SetBusCLK_32M(void)
{
CLKSEL=0X00; //disengage PLL to system
PLLCTL_PLLON=1; //  on PLL
SYNR =0xc0 | 0x08;
REFDV=0x60 | 0x04;
POSTDIV=0x00;    //pllclock=2*osc*(1+SYNR)/(1+REFDV)=64MHz;
_asm(nop);       //BUS CLOCK=32M
_asm(nop);
while(!(CRGFLG_LOCK==1)); //when pll is steady ,then use it;
CLKSEL_PLLSEL =1;       //engage PLL to system;
}

      void main(void)
{             SetBusCLK_32M();
   for(;;) { liushui();}}

我要看看你的硬件电路是怎么连接的
