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,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,TIM4(控制LED闪烁)

SC:80-1,ARR:10000-1。
5.ADC

B15作为ADC2IN15通道，开启single-ended模式。
6.EEPROM

B6,PB7输出模式。

三、代码实现
bsp组有:

在这里只展示interrupt.h,interrupt.h,main.c,main.h的代码，其他文件的代码可到基本模块篇获取。
interrupt.h:

#ifndef __INTERRUPT_H__
#define __INTERRUPT_H__
#include "main.h"
#include "stdbool.h"
struct keys
{
bool key_sta;
unsigned char judge_sta;
bool single_flag;
unsigned int key_time;
bool long_flag;
};
#endif

复制代码

interrupt.c:

#include "interrupt.h"
#include "lcd.h"
#include "stdio.h"
char RxBuffer[30];
unsigned char BufIndex;
unsigned char Rxdat;
extern unsigned char LEDTime;
extern unsigned char LED;
unsigned char LEDType;
extern unsigned char ledMode;
struct keys key[4] = {0, 0, 0, 0, 0};
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
RxBuffer[BufIndex++] = Rxdat;
HAL_UART_Receive_IT(huart, &Rxdat, 1);
}
void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
{
if(htim->Instance == TIM3)
{
key[0].key_sta = HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_0);
key[1].key_sta = HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_1);
key[2].key_sta = HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_2);
key[3].key_sta = HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_0);
for(unsigned char i = 0; i < 4; i++)
{
switch(key[i].judge_sta)
{
case 0:
{
if(key[i].key_sta == 0)
{
key[i].judge_sta = 1;
key[i].key_time = 0;
}
break;
}
case 1:
{
if(key[i].key_sta == 0)
{
key[i].judge_sta = 2;
}
else
{
key[i].judge_sta = 0;
}
break;
}
case 2:
{
if(key[i].key_sta == 1)
{
key[i].judge_sta = 0;
if(key[i].key_time <= 80)
{
key[i].single_flag = 1;
}
}
else
{
key[i].key_time++;
if(key[i].key_time > 80)
{
key[i].long_flag = 1;
}
}
break;
}
}
}
}
if(htim->Instance == TIM4)
{
LEDTime++;
if(ledMode == ON)
{
if(LEDTime == 20)
{
LEDType = !LEDType;
LED = LED & 0xfe | LEDType;
LEDTime = 0;
}
}
}
}
