51单片机:实现CSGO中C4下包功能(附功能实现视频和代码详解)

2024-11-10 来源:个人技术集锦


 

一、功能实现

51单片机实现CSGO中C4下包

 

二、功能简介

1.矩阵键盘输入密码

按键密码
S11
S22
S33
S44
S55
S66
S77
S88
S99
S100

2.S11确认输入密码

		if(KeyNum)//等价于if(KeyNum!=0)----非零即真
		{
			if(KeyNum<=10)//如果S1~S10按键按下,输入密码
			{
				if(InputCount<7)
				{
					InputCount++;
					LCD_ShowNum(2,InputCount,KeyNum,1);
					
				}
							
			}
			
			if(KeyNum==11) //如果S11按键按下
			{			
				LCD_ShowNum(2,1,Password,7);
				LCD_ShowString(2,1,"*******");
            }
        }

3.启用蜂鸣器

void Buzzer_Time(unsigned int ms)//蜂鸣器时长
{
	unsigned int i;
	for(i=0;i<ms*2;i++)
	{	
		Buzzer=!Buzzer;	
		Buzzer_Delay700us();
		//每700微秒翻转一次,一个周期是1.4毫秒,频率是698Hz
				
	}
}

三、模块化代码

1.Buzzer.h

#ifndef __BUZZER_H__
#define __BUZZER_H__

void Buzzer_Time(unsigned int ms); 

#endif

2.Buzzer.c

#include <REGX52.H>

//蜂鸣器端口
sbit Buzzer=P2^5;
//sbit位控制宏,可以将单片机的某个引脚或寄存器的特定位映射为一个C语言的变量。
//格式如下
//sbit <位变量名>=<引脚或者寄存器地址>.<位号>;
//解释:位变量名        是给这个位定义的变量名
//引脚或者寄存地地址    是所控制的引脚或者寄存地地址
//位号                  表示所要控制的位在引脚或寄存器中的位置



/**
  * @brief  蜂鸣器私有延时函数,延时500us
  * @param  无
  * @retval 无
  */


void Buzzer_Delay700us(void)	
{
	unsigned char data i, j;

	i = 2;
	j = 61;
	do
	{
		while (--j);
	} while (--i);

	
}



/**
  * @brief  蜂鸣器发声
  * @param  ms(发声时长)
  * @retval 无
  */


void Buzzer_Time(unsigned int ms)//蜂鸣器时长
{
	unsigned int i;
	for(i=0;i<ms*2;i++)
	{	
		Buzzer=!Buzzer;	
		Buzzer_Delay700us();
		//每700微秒翻转一次,一个周期是1.4毫秒,频率是698Hz
				
	}
}

3.MatrixKey.h

#ifndef __MATRIXKEY_H__
#define __MATRIXKEY_H__

unsigned char MatrixKey();

#endif

4.MatrixKey.c

#include <REGX52.H>
#include "Delay.h"
