一、题目

二、模块初始化
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B0,B1,B2,B3不要弄错了
3.LED:开启PC8,PC9,PD2输出模式就行了。
4.定时器:TIM3(按键消抖定时器)

SC:80-1,ARR:10000-1,TIM2CH2(PA1PWM占空比以及频率)

SC:800-1,ARR:100-1,TIM4(控制PWM转换时间以及LD1亮光时间)

SC:80-1,ARR:9999, TIM6(控制LD2闪烁)

SC:800-1,ARR:9999。
5.USART，波特率9600，异步通信模式。

三、代码实现
bsp组**有:

interrupt.h:

#ifndef __INTERRUPT_H__
#define __INTERRUPT_H__
#include "main.h"
#include "stdbool.h"
struct keys
{
bool key_sta;
unsigned char key_judge;

#endif
