  10. C51单片机——实现用独立按键控制LED亮灭（调用函数篇） - 2

    说在前面这部分我本来是合为一篇来写的，因为目的是一样的，都是通过独立按键来控制LED闪灭本质上是起到开关的作用，即调用函数和中断函数。但是写一篇太累了，我还是决定分为两篇写，这篇是调用函数篇。在本篇中你主要看到这些东西！！！1.调用函数的方法（主要讲语法和格式）2.独立按键如何控制LED亮灭3.程序中的一些细节（软件消抖等）1.调用函数的方法思路还是比较清晰地，就是通过按下按键来控制LED闪灭，即每按下一次，LED取反一次。重要的是，把按键与LED联系在一起。我打算用K1来作为开关，看了一下开发板原理图，K1连接的是单片机的P31口，当按下K1时，P31是与GND相连的，也就是说，当我按下去时
