前言
学完了基本模块，就要开始刷题了，先把省赛过了再考虑国赛的事情吧。
一、题目
二、模块初始化
这里就简单描述一下模块的配置方法，具体方法到基本模块中有描述。
1.LCD这里不用配置，直接使用提供的资源包就行
2.KEY, 四个按键IO口都要配置，分别是PB0, PB1,PB2,PA0依次是B1,B2,B3,B4不要弄错了
3.PWM:这里使用TIM16的CH1和TIM17的CH1作为发生通道，TIM16→PSC:800-1,ARR:100-1,Pulse:80
TIM17→PSC:400-1,ARR:100-1,Pulse:60
4.LED:开启PC8,9,10,11,12,13,14,15输出模式就行了
5.RTC:详见RTC模块部分，配置方法一样的
6.定时器:由于题目的逻辑比较复杂(笔者个人认为)，所以除了开TIM16,TIM17外还要开TIM2,3,4,6,7,8,15,而且中断要全部打开。
三、代码实现
1.void DisposeKey(void); //按键响应函数
void DisposeKey(void)
