屏幕函数-国赛
.提供一般的题目选择和控制相关功能函数的运行。
.支持在屏幕上直接调参，对参数具有断电保护，锁定保护的功能。
.未加入ucos操作系统（近年来电赛中还没有必要用到操作系统）
.此文件针对stm32f103zet6开发板，提供底层的屏幕显示和操作控制功能，具体比赛要求的功能应自行写成单独的模块加入此文件中即可运行。(1. provides general topic selection and control of the function of the function.
2. supports the direct parameter adjustment on the screen, the power failure protection for the parameters and the function of locking the protection.
3. not added to the UCOS operating system (there is no need to use the operating system in recent caller calls)
4., this document provides the bottom screen display and operation control function for the stm32f103zet6 development board, and the function of specific match request should be written into a separate module by itself.)
