代码说明：

说明：  这是基于开发板LPC1114的源码程序，是用C语言编写，用于实现LED灯的点亮以及开关的控制，同时它也是一个完整的模板，可以在此基础上添加其他程序用于开发板的学习，是一个完整的模板，可直接使用。(This is based on the development board LPC1114 source code program, is written in C language, used to realize the lighting of LED lights and switch control, at the same time, it is also a complete template, you can add other programs on this basis for the development board learning, is a complete template, can be used directly.)
