说明：  只用于学习STM32F429的ADC，将一路ADC采集，改为两路ADC采集，并将采集的模拟量转换为紫外线等级。(It is only used to learn the ADC of STM32F429. It changes one ADC acquisition to two ADC acquisitions, and converts the analog acquisition to ultraviolet level.)

说明：  vb与plc通讯帮助解决vb与plc通讯之间的问题(vb and Communications plc)

学习如何用STM32做USB与PC通讯.使用了片上RAM模拟一个U盘,对初学USB的童鞋很有帮助.(Learning with STM32 USB and PC communications. Use of on-chip RAM to simulate a U disk, USB of children' s shoes helpful for beginners.)

单片微型计算机简称单片机，是典型的嵌入式微控制器（Microcontroller Unit）， 单片机芯片 常用英文字母的缩写MCU表示单片机，单片机又称单片微控制器，它不是完成某一个逻辑功能的芯片，而是把一个计算机系统集成到一个芯片上。(Microcontroller chip microcomputer referred to, is a typical embedded microcontroller (Microcontroller Unit),     Single chip Commonly used letters of the abbreviation indicates MCU microcontroller, microcontroller, also known as single-chip microcontroller, it is not complete a certain logic functions of the chip, but to a computer system integrated into a single chip.)

键盘的测试功能，用于测试开发系统时的按键状态(Keyboard test functions, the development of systems for testing the key state)

单片机虚拟串口仿真图，里面有虚拟串口软件和串口调试助手，还有用proteus进行的仿真图，不用开发板一样进行仿真，只能说proteus太强大了。只要你想不到的，没有他做不到的！(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)

实现声音导引小车运动，智能小车程序C51代码(Achieve sound AGV Sport, smart car program code C51)

超声波测距模块扩展实验，使用超声波传感器，把数据结果显示在1602上。(Ultrasonic Ranging Module extension experiments using ultrasonic sensors, and display data results in 1602.)
