参考gitee移植，key_board: 用于单片机中的小巧多功能按键支持；最强功能：支持不限数量、任意按键、任意按键的任意状态之间的随意组合！！！ (gitee.com)
支持：
- 矩阵键盘
- 单io按键
注：在此没有做矩阵键盘，注意按键的电气属性设置，引脚初始化默认是按键上拉，按下为低电平，要根据实际修改。

一、单个按键功能
移植包含key_board.c，key_board.h，key_board_config.h key_board_sample.h key_board_sample.c （在此基础上修改即可）
一、key_board_sample.h 文件引脚信息
1.修改引脚宏
2.添加按键数
3.修改引脚初始化时钟
二、key_board_sample.c文件引脚信息
1.添加按键引脚信息
2.定义按键id及功能结构体
二、组合按键
main.c中
结构体功能初始化
static unsigned int test_id1, test_id2;
//注册组合状态
const struct key_combine_t test_combine1[] = {
{ .id = KEY_UP, .state = KEY_PRESS },
{ .id = KEY_DOWN, .state = KEY_PRESS_LONG },
{ .id = KEY_UP, .state = KEY_PRESS },
};
const struct key_combine_t test_combine2[] = {
{ .id = KEY_UP, .state = KEY_PRESS },
{ .id = KEY_DOWN, .state = KEY_PRESS },
{ .id = KEY_UP, .state = KEY_PRESS },
{ .id = KEY_DOWN, .state = KEY_PRESS },
};
循环执行
//组合按键
if(key_check_combine_state(test_id1))
{
printf("combine test_id1\r\n");
}
if(key_check_combine_state(test_id2))
{
printf("combine test_id2\r\n");
