關(guān)于Timer16_0代碼：

  LPC_SYSCON->SYSAHBCLKCTRL |= (1<<7);                 //開(kāi)啟定時(shí)器時(shí)鐘
  LPC_TMR16B0->PR=1000;//1000-1;                       //預(yù)分頻計(jì)數(shù)器
  LPC_TMR16B0->MR0=12000;                              //匹配寄存器

Timer16_0中斷程序：

 void TIMER16_0_IRQHandler(void)
{ 
  if ( LPC_TMR16B0->IR & 0x1 )
  {
   LPC_TMR16B0->IR = 1;   /* clear interrupt flag */
  
  //timer16_0_counter++;
  
   GPIOSetValue( 0, 3, 0 );             //給P0.3位寫(xiě)0
  Delay_Ms(100);
  GPIOSetValue( 0, 3, 1 );             //給P0.3位寫(xiě)0
  Delay_Ms(100);
  }
  if ( LPC_TMR16B0->IR & (0x1<<4) )
