有没有大佬能写一个按键LED灯交替闪烁的keil5里的编程

void main()

{

WDTCTL = WDTPW + WDTHOLD; //关看门狗

P1DIR |= BIT0；
P1DIR |= BIT5; ////P1.0 P1.5 设置为输出

P3DIR = ~( BIT2); //P3.2 设置为输入

P1REN |= BIT0 + BIT5; //上拉下拉电阻使能


P1IE |= BIT0 + BIT5; //P1.0 P1.5中断使能

P2IFG =0; //中断标志清除，防止配置过程中出现中断标志为1

_EINT(); //开总中断

}

/*******************端口中断程序********************/

#pragma vector = PORT2_VECTOR

__interrupt void port2(void)

{

switch(P2IV)

{

case 0x0e: P1OUT ^= BIT0;break; //LED1 亮灭

case 0x10: P1OUT ^= BIT5;break; //LED2 亮灭

default :break;

}

}

全的
如有帮助，望采纳

这多简单的逻辑，给一个变量k，按键按一次，k<4,k+1,如果k>=4直接赋值k=0，然后k在0-3区间，4个数值对应4种状态就好
