超声波测距（5 28线性处理）,测量线性度很高(Ultrasonic Ranging (528 linear processing), high linearity measurements)

rs232实验 可以看看是综合实验 需要的人 是51的板子 用keil编译(the rs232 experiment to see people in need of comprehensive experimental 51 board keil compiler)

说明：  无线通信接受模块程序，内含数模转换应用程序。(Wireless receiving module program that includes digital to analog conversion applications.)

A program to consicle very mad and good !! yes :

AVRstudio和winavr的联用，多个文档，对于刚刚入门的单片机爱好者们非常有用。(AVRstudio and winavr hyphenated, multiple documents, for just getting started microcontroller enthusiasts very useful.)

说明：  本压缩包中详细介绍了电动机的单片机控制的有关方法(The compression package described in detail the single-chip motor control of the method)

利用stm32上自带的ad和da进行模数和数模转换实验(Use the built-in ad and da stm32 analog to digital and digital to analog conversion experiments)

51单片机的串口通信程序，来自于开发板，VC环境下编写。(51 the Serial communication program, and from the development board, VC environment prepared.)

51单片机考勤系统下位机程序，可以配合上位机软件实现考勤功能，将hex文件下载到51单片机即可使用(51 MCU control procedures can be achieved with the PC software attendance function, the hex file into the microcontroller 51 can be used)

虚拟串口，在Proteus中可用实际串口与其通信(Virtual serial port, available at Proteus its actual serial communication)
