使用2543和C51单片机进行电压的实时测量

详细介绍SRM 60V 开发板的使用和测试方法；(Detail the use and testing methods SRM 60V Development Board )

说明：  这是我认为51汇编里面比较好理解的书籍，以及我简单整理的汇编指令文档一份。入门学习还是不错的。(This is a book that I think is better understood in the 51 assembly, as well as a document of assembly instructions that I simply organized. Initial study is still good.)

毕业设计项目，高精度激光测距仪电路和PCB文件(毕业设计项目，高精度激光测距仪电路和PCB文件 毕业设计项目，高精度激光测距仪电路和PCB文件 Graduated design project, high precision laser range finder circuit and PCB file)

Simplicity Studio下的EFM8SB1例程(One Program of EFM8SB under Simplicity Studio)

基于51单片机的电能表软件设计，电能测量芯片是ATT7022C，有完整的读写和校表程序，已通过测试。(SCM based on the 51 Meter software design, power measurement chip ATT7022C, and write a complete calibration procedures, it has been tested.)

2路18B20采集程序，读取两路温度，两路温度同时利用单总线原理读取内部温度并显示在1602上(2-way 18B20 acquisition program that reads two temperature, two temperature while using the principle of a single bus read the internal temperature and display in 1602)

SX1276底层程序，带Contiki系统适用于物联网开发！(SX1276 underlying program with Contiki system is suitable for the Internet of things development!)

基于M0516的魔球灯控制程序，内含原理图，功能有内置PWM加模拟PWM线性调光，炫耀的自走程序与声控程序，主从控制模式，IIC协议，485通讯DMX512协议，74HC595控制四位3461共阴数码管，ULN2803电机驱动程序(M0516 based magic ball lamp control procedures, the enclosed schematic diagram, function has a built-in PWM analog PWM linear dimming, showing off the go program with voice control, master-slave control mode, the IIC agreement, 485 communication DMX512 protocol, 74 hc595 are needed to control the four digital tube, 3461, a total of Yin ULN2803 motor drivers)

说明：  STC单片机多机连级串口程序可实现.416路控制. 串口和485都可以使用、 一个程序可以用在26块控制板上，通过拔码开关给板子编号，每块板可以过滤分析所接收到不同的代码。进行继电器的动作，能返回数据，因使用定时器发送返回，不会阻塞或者代码错乱、可以 用在中控，物联网，等各种控制场合。修改代码后，能达到上千路的控制。(STC single-chip microcomputer multi-level serial port program can realize 416 channel control. Serial port and 485 can be used. One program can be used on 26 control boards. Each board can filter and analyze different codes received by numbering the boards with the pull-out switch. Relay operation can return data, because the timer is used to send the return, it will not block or code confusion, and can be used in central control, Internet of things, and other control occasions. After modifying the code, it can achieve thousands of control.)

使用到蜂鸣器、Lcd1602、ZLG7289和串口，键盘实现加法器，控制LCD1602和蜂鸣器音乐播放。借助串口调试助手，可以用电脑发送字符，替代键盘，完成上述三种功能。(To use the buzzer, Lcd1602, ZLG7289 and serial port, a keyboard adder, and a buzzer control LCD1602 music player. With serial debugging assistant, a computer can send characters, instead of the keyboard, the above three functions.)
