一、功能实现
<iframe allowfullscreen="true" data-mediaembed="csdn" frameborder="0" id="VM9ZV9v0-1720774168675" src="https://live.csdn.net/v/embed/408999"></iframe>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 |
S1 | 1 |
S2 | 2 |
S3 | 3 |
S4 | 4 |
S5 | 5 |
S6 | 6 |
S7 | 7 |
S8 | 8 |
S9 | 9 |
S10 | 0 |
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
/**
