MSP430F1101A单片机按键及LED的检测程序 [复制链接]

主要实现MSP430F1101A单片机的时钟设置及按键对应LED的显示

单片机源程序如下:
#include <msp430x11x1.h>

int main( void )
{
  // Stop watchdog timer to prevent time out reset
  WDTCTL = WDTPW + WDTHOLD;
P2DIR |= 0X01;
P2OUT |= BIT0;
P1DIR &= ~BIT0;
P1IE |= 0X01;
P1IES |= 0X01;
P1IFG &= ~0X01;
_BIS_SR(LPM4_bits+GIE);
}

# pragma vector=PORT1_VECTOR
__interrupt void port_1(void)
{
  unsigned int i;
  if (!(P1IN & BIT0))
  {
    for(i=0;i<8000;i++);
    if (!(P1IN & BIT0))
    {
      P2OUT &= ~BIT0;
      while(!(P1IN & BIT0));
      P2OUT |= BIT0;
    }
  }
  //P2OUT ^= 0X01;
  P1IFG &= ~0X01;
}
