前言

这也是由于身边的人的相关需求

了解一下单片机的相关的东西

呵呵当然这里仅仅是一些简单的测试用例

仅仅是为了学习之用, 当然还可以做一些其他的东西

我这里的是做一个花里胡哨的生日快乐

主控制程序

整体程序的结构如下, Test01LedPrint 是主控制程序, utils 是公共的东西

birthdayLed 是 led 点阵输出祝福的图案处理

lightToggleLed 是控制 led 灯泡的闪烁的相关处理

lightTube 是控制输出数码管的相关信息

birthdaySong 是输出基于蜂鸣管生日快乐, 但是消耗有点大, 不能组合其他三个使用

主要是组装各个业务程序


#include "utils.h"
#include "birthdayLed.h"
#include "lightToggleLed.h"
#include "lightTube.h"
#include "birthdaySong.h"


/**
 * main related
 */
long counter = 1;


void main() {

    while (1) {

        // printLed(counter);
		// lightToggleLed(counter);
		 lightTube(counter);
		// playMusic(counter);

		delay_ms(5);
        counter++;

    }
}

utils.h

#ifndef _utils_H
#define _utils_H

#include "reg52.h"

typedef unsigned int u16;
typedef unsigned char u8;
typedef unsigned long u32;

/**
 * delay $delayIn10Us us
 * @param ten_us
 */
void delay_10us(u16 ten_us);

/**
 * delay $delayInMs ms
 * @param ms
 */
void delay_ms(u16 ms);

/**
 * control led[pos] on/off
 * @param pos
 * @param on
 */
void ledCtl(u8 pos, u8 on);

/**
 * toggle led[pos] on/off
 * @param pos
 * @param on
 */
void ledToggle(u8 pos);

#endif

utils.c



#include "utils.h"


void delay_10us(u16 ten_us) {
    while (ten_us--);
}


void delay_ms(u16 ms) {
    u16 i, j;
    for (i = ms; i > 0; i--)
        for (j = 110; j > 0; j--);
}


void ledCtl(u8 pos, u8 on) {
    if(on == 0) {
        P2 |= (1 << pos);
        return;
    }
    P2 &= (~(1 << pos));
}


void ledToggle(u8 pos) {
    P2 ^= (1 << pos);
}

led 点阵的控制

birthdayLed.h

#ifndef _birthday_led_H
#define _birthday_led_H


#include "utils.h"


sbit SHIFT_REG_INPUT = P3 ^6;
sbit STORE_REG_INPUT = P3 ^5;
sbit SERIAL_PORT_INPUT = P3 ^4;

#define LEDDZ_COL_PORT P0


/**
 * do biz for printLed
 */
void printLed(int);

/**
 * output word 2 led
 */
void hc595_write_data(u8);

/**
 * output word 2 led
 */
void printLedWord(int, u8 *);

#endif

birthdayLed.c

就是依次输出各个图案



#include "birthdayLed.h"


/**
 * led related
 */
u8 gled_words[][8] = {
{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},
{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},
{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},

{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},
{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},

{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},
{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},
{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},

{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},
{0x38,0x7C,0x7E,0x3F,0x3F,0x7E,0x7C,0x38},
};
u8 gled_col[8] = {0x7f, 0xbf, 0xdf, 0xef, 0xf7, 0xfb, 0xfd, 0xfe};

long ledTurnNextThreshold = 30;
int ledMaxRowCount = 17;
int ledCurrentRowIdx = 0;


void printLed(int counter) {
    u8 *word;
    if (counter % ledTurnNextThreshold == 0) {
        ledCurrentRowIdx = (ledCurrentRowIdx + 1) % ledMaxRowCount;
    }

	if(counter % 2 == 0) {
		word = gled_words[ledCurrentRowIdx];
   		printLedWord(8, word);
	}
}


void hc595_write_data(u8 dat) {
    u8 i = 0;

    for (i = 0; i < 8; i++) {
        SERIAL_PORT_INPUT = dat >> 7;
        dat <<= 1;
        SHIFT_REG_INPUT = 0;
        delay_10us(1);
        SHIFT_REG_INPUT = 1;
        delay_10us(1);
    }
    STORE_REG_INPUT = 1;
    delay_10us(1);
    STORE_REG_INPUT = 0;
}


void printLedWord(int wordLength, u8 *word) {
    u8 i;
    for (i = 0; i < wordLength; i++) {
        LEDDZ_COL_PORT = gled_col[i];
        hc595_write_data(word[i]);
        delay_10us(10);
        hc595_write_data(0x00);
    }
}

实际效果如下图

led 灯的控制

lightToggleLed.h

#ifndef _light_toggle_led_H
#define _light_toggle_led_H


#include "utils.h"


/**
 * do biz for lightToggleLed
 */
void lightToggleLed(int);

#endif

lightToggleLed.c

主要是编排一个周期, 然后控制这个周期内的 led 的状态切换



#include "lightToggleLed.h"

long lightToggleTurnNextThreshold = 10;
int lightToggleMaxRowCount = 10;
int lightToggleCurrentRowIdx = 0;

u16 ledToggleConfigs[][10] = {
        {3, 5, 8, 9},
        {2, 4, 7, 8, 9},
        {0},
        {0},
        {0},
        {1, 3, 8, 9},
        {4, 5, 6, 9},
        {3, 6, 7 ,8, 9},
};
u16 ledToggleConfigLengths[8] = {4, 5, 0, 0, 0, 4, 4, 5};

void lightToggleLed(int counter) {
    u8 ledIdx;
    int i, length;
    u16 *toggleConfig;
    if (counter % lightToggleTurnNextThreshold == 0) {
        lightToggleCurrentRowIdx = ((lightToggleCurrentRowIdx + 1) % lightToggleMaxRowCount);
    }

    for(ledIdx = 0; ledIdx < 8; ledIdx ++) {
        if(ledIdx >= 2 && ledIdx <= 4) {
            continue ;
        }

        toggleConfig = ledToggleConfigs[ledIdx];
        length = ledToggleConfigLengths[ledIdx];
        for(i=0; i<length; i++) {
            if((toggleConfig[i] == lightToggleCurrentRowIdx) && (counter % lightToggleTurnNextThreshold == 1)) {
                ledToggle(ledIdx);
            }
        }
    }
}

实际效果如下

数码管的控制

lightTube.h

#ifndef _light_tube_H
#define _light_tube_H


#include "utils.h"


sbit LSA=P2^2;
sbit LSB=P2^3;
sbit LSC=P2^4;


#define SMG_A_DP_PORT	P0


/**
 * do biz for lightTube
 */
void lightTube(int);

#endif

lightTube.c

这个就是控制数码管的数字的展示了

索引相关控制和 led的控制重合了



#include "lightTube.h"

u8 gsmg_code[17]={0x3f,0x86,0x3f,0x6d,0x23,0x08,0x08,0x23};


void lightTube(int counter) {
	u8 i=0;

	for(i=0;i<8;i++)
	{
	   	switch(i)//位选
		{
			case 0: LSC=1;LSB=1;LSA=1;break;
			case 1: LSC=1;LSB=1;LSA=0;break;
			case 2: LSC=1;LSB=0;LSA=1;break;
			case 3: LSC=1;LSB=0;LSA=0;break;
			case 4: LSC=0;LSB=1;LSA=1;break;
			case 5: LSC=0;LSB=1;LSA=0;break;
			case 6: LSC=0;LSB=0;LSA=1;break;
			case 7: LSC=0;LSB=0;LSA=0;break;
		}
		SMG_A_DP_PORT=gsmg_code[i]; 
		delay_10us(10); 
		SMG_A_DP_PORT=0x00; 
	}
}

实际效果如下图

蜂鸣管控制

birthdaySon.h



#ifndef _birthday_song_H
#define _birthday_song_H


#include <utils.h>


sbit BEEP = P2^5;


void playMusic(int);


#endif

birthdaySon.c



#include "birthdaySong.h"

u8 code SONG_TONE[]={ 212, 212, 190, 212, 159, 169, 212, 212, 190, 212, 142, 159, 212, 212, 106, 126, 159, 169, 190, 119, 119, 126, 159, 142, 159, 0 };
u8 code SONG_LONG[]={ 9, 3, 12, 12, 12, 24, 9, 3, 12, 12, 12, 24, 9, 3, 12, 12, 12, 12, 12, 9, 3, 12, 12, 12, 24, 0 };


long birthdaySongTurnNextThreshold = 1;
int birthdaySongMaxRowCount = 26;
int birthdaySongCurrentRowIdx = 0;

long birthdaySongNextAvailableCounter = -1;
long birthdaySongSleepAfterEndIn5Ms = 1000;

void playMusic(int counter) {
	u16 toneNow, longNow;
	u16 j, k;
	if(counter <  birthdaySongNextAvailableCounter) {
		return ;
	}
    if (counter % birthdaySongTurnNextThreshold == 0) {
        birthdaySongCurrentRowIdx = birthdaySongCurrentRowIdx + 1;
        birthdaySongCurrentRowIdx = birthdaySongCurrentRowIdx % birthdaySongMaxRowCount;
    }

	toneNow = SONG_TONE[birthdaySongCurrentRowIdx];
	longNow = SONG_LONG[birthdaySongCurrentRowIdx];
	if(toneNow == 0) {
		birthdaySongNextAvailableCounter = counter + birthdaySongSleepAfterEndIn5Ms;
		BEEP = 0;
		return ;
	}
	for (j = 0; j < longNow * 20; j++) {
    	BEEP = !BEEP;
		for (k = 0; k < toneNow / 5; k++);
	}

}

这个无法展示, 可以自己听

数码管, led灯, led点阵大合计

完
