单片机模块化编程_单片机模块化编程实例 数组怎么写

概述

        1、青铜示例：

#include <stdio.h>
 
enum {
    LED1,
    LED2,
    LED3,
    LED_NUM
};
 
void Func_LED1(unsigned char state);
void Func_LED2(unsigned char state);
void Func_LED3(unsigned char state);
 
/**
 * 函数指针数组定义格式
 * 函数返回类型 (*指针变量名[数组大小])(函数参数列表);
 * @param state
 * @return
 *
 */
void (*func[LED_NUM])(unsigned char state) = {Func_LED1, Func_LED2, Func_LED3};
 
void Func_LED1(unsigned char state)
{
    if (state)
        printf("LED1 ON\r\n");
    else
        printf("LED1 OFF\r\n");
}
 
void Func_LED2(unsigned char state)
{
    if (state)
        printf("LED2 ON\r\n");
    else
        printf("LED2 OFF\r\n");
}
 
void Func_LED3(unsigned char state)
{
    if (state)
        printf("LED3 ON\r\n");
    else
        printf("LED3 OFF\r\n");
}
 
int main() {
 
//    for (int i = 0; i < LED_NUM; ++i) {
//        func[i](1);
//    }
 
    func[LED1](1);
    func[LED2](1);
    func[LED3](1);
 
    return 0;
}

key.h文件

//
// Created by champion on 2021/11/30.
//
 
#ifndef UNTITLED1_KEY_H
#define UNTITLED1_KEY_H
 
typedef enum {
    KEY1,
    KEY2,
    KEY_NUM,
}KEY_ID_TYDEF;
 
typedef enum {
    KEY_IDLE,       //空闲
    KEY_PRESS,      //短按
    KEY_LONG_PRESS, //长按
    KEY_RELEASE,    //释放
}KEY_STATE_TYDEF;
 
 
 
 
typedef void (*pKeyScanCallBack) (KEY_ID_TYDEF KEY_ID, KEY_STATE_TYDEF KEY_STATE);
 
void keyScanCBRegister(pKeyScanCallBack pCB);
void keyInit(void);
void keyPoll(void);
 
#endif; //UNTITLED1_KEY_H

key.c文件

//
// Created by champion on 2021/11/30.
//
#include <stdio.h>
#include "key.h"
 
KEY_ID_TYDEF keyID;
KEY_STATE_TYDEF keyState;
pKeyScanCallBack pkeyScanCB;
 
 
void keyInit(void)
{
    keyID = 0;
    keyState = KEY_IDLE;
    pkeyScanCB = NULL;
}
 
void keyScanCBRegister(pKeyScanCallBack pCB)
{
    if (pkeyScanCB == NULL) {
        pkeyScanCB = pCB;
    }
}
 
 
void keyPoll(void)
{
    printf("Please Enter key ID: \r\n");
    if (scanf("%d", &keyID) == 1) {
        printf("\r\n");
        printf("Please Enter key state: \r\n");
        if (scanf("%d", &keyState) == 1) {
            //keyScanHandle(keyID, keyState) 这里相当于下面这句话，通过这样的方法，封装好硬件层于应用层的API
            if (pkeyScanCB != NULL) {
                pkeyScanCB(keyID, keyState);
            }
        }
    }
}

main.c文件

#include <stdio.h>
#include "key.h"
#include "stdint.h"
 
typedef struct {
    uint8_t value;
    void (*run_func)(void);
}FuncTYpedef;
 
 
void keyScanHandle(KEY_ID_TYDEF KEY_ID, KEY_STATE_TYDEF KEY_STATE)
{
    printf("KEY_ID :%d, KEY_STATE :%d \r\n", KEY_ID, KEY_STATE);
}
 
 
void run_fun(void)
{
    keyInit();
    keyScanCBRegister(keyScanHandle);
    keyPoll();
}
 
int main() {
 
    /**
     * 定义结构体变量
     * */
    FuncTYpedef init_fun = {
            .value = 10,
            .run_func = run_fun,
    };
    init_fun.value = 100;
    init_fun.run_func();
 
    /**
     * 结构体变量指针变量
     */
//    FuncTYpedef *pFun = {
//           // pFun->value = 0,
//            pFun->run_func = run_fun,
//    };
//    pFun->value = 200;
//    pFun->run_func();
 
    return 0;
}
