二、使用方法：

直接调用即可。

void main()
{
    DISABLE_INTERRUPTS;                          //MPU上电，各模块功能初始化前需要关中断
    system_init();                               //各模块功能初始化
    ENABLE_INTERRUPTS;                           //开中断使能

    OLED_Init();  

    Menu_Refresh();

    while(1)
    {

      Menu_Key_Detect();

    }
}
