MSP430G2452按键控制P1.0口LED灯亮灭

MSP430G2452按键(P1.3)控制P1.0(LED)灯亮灭C语言程序，P1.3为带上拉电阻的输入状态，P1.0为输出状态，当P1.3按下，P1.0口LED灯则亮，松开按键，LED灯则熄灭，无限循环的下去！程序如下：

#include "msp430g2452.h"

void main(void)

{

WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer

P1DIR = 0x01; // P1.0 output, else input

P1OUT = 0x08; // P1.3 set, else reset

P1REN |= 0x08; // P1.3 pullup

while (1) // Test P1.3

{

if(0x08 & P1IN)

{

P1OUT |= 0x01; // if P1.3 set, set P1.0

}

else P1OUT &= ~0x01; // else reset

}

}
