写了一个方法比较全面的头文件：

3 // 头文件功能简介：编写了一个驱动led灯的头文件:
4 // 所有函数都是按位操作的：
5 // set_xxx_xxx_xxxx_xxxx_xxx(collection) // 设置选中位为有效状态
6 // set_xxx_xxx_xxxx_xxxx_xxx(0x05) // 设置gpio 0,3 引脚为有效状态
7 // clean_xxx_xxx_xxxx_xxxx_xxx(collection) // 清除选中位为有效状态
8 // clean_xxx_xxx_xxxx_xxxx_xxx(0x05) // 清除gpio 0,3 引脚为有效状态
9 // ---------------------------------------------------------------------------------------------------------------
10 # include <intrins.h> // 左右移位头文件
11 # include "bsp.h" // 板卡的gpio宏定义，定义内容如下
12 // ---------------------------------------------------------------------------------------------------------------

默认stc51单片机举例，代码方法比较全面，选择适合的自己的就行。
本代码默认支持8位的lcd排灯，需要扩列的自行修改代码。
