ALARM-FOR-VOLTAGE

基于51单片机的环境噪声检测仪 含proteus仿真文件一份noise.dsn Keil工程文件一套 主程序代码main.c 6篇相关文献及毕业设计论文 仿真通过(Based on 51 single-chip environmental noise detector proteus simulation file containing a set of project files noise.dsn Keil main code main.c 6 relevant articles and graduation thesis design through simulation)

一个倒车雷达的程序 使用的是AVR单片机。 在include.h文件里面定义 #define CPU_F 4 //4MHZ 定义外晶振的频率 #define GOOD //40KHZ更准确 #define DIS150CM //若定义了，1.5M有效，没有定义就是2.5M有效 #define DEBUG //若定义了，则是调试模式debug , 没定义就是release模式 (Include.h document in which the definition of# define CPU_F 4// 4MHZ definition of the frequency of oscillator# define GOOD// 40KHZ more accurate# define DIS150CM// if defined, 1.5M effective, efficient 2.5M is not defined# define DEBUG// If defined, it is debug mode debug, not release model is defined as)

通过51单片机控制MAX110实现AD转换C源代码 (51 Controlled by AD converter MAX110 C source code to achieve)

RC522的51例程，包括电路图等，非常适合初学者。(51 of RC522 routines, including circuit diagrams, very suitable for beginners.)

The secret cipher that secures Mifare Classic RFID tags used in access control systems

51单片机常用的C程序例子。非常适合单片机控制多媒体方面的(51 SCM common example of C program. Very suitable for microcomputer control of multi-media)

说明：  单片机驱动3310 lcd显示屏的c程序，单片机与屏的线路连接可以参见程序中的宏定义。程序写得很精简，但是很好用。(Microprocessor 3310 LCD display c procedures, SCM and the screen can see the line connecting the procedures macro definition. Very streamlined procedures, but is useful.)

使用mpu6050的dmp获得的欧拉角和四元数(Dmp obtained using mpu6050 of Euler angles and quaternion)

采用ds18b20测温，采用数码管显示，汇编(To adopt ds18b20 temperature measurement, digital display, assembly)

某公司安装了电子门，要设计门禁系统： 公司的雇员可以凭借密码、胸卡或指纹进入公司 计算机根据雇员的验证方式对其身份进行验证 管理员在监控室可以通过按钮直接开启电子门 访客可以按门铃请求进入，由管理员为其放行 管理员可以为新职员设置密码 (A company to install an electronic gate, to design access control systems: the company' s employees can rely on passwords, badges or finger into the company computer, authentication of the employee to verify their identity can be an administrator in the control room directly through the button to open electronic gates that visitors can rang the doorbell of the request to enter an administrator can be released by the administrator of its staff to set a password for the new)
