protues的教程，初学者的必备，可以学习很多东西，对自己收益很大(study protues)

A C code and hardware for a wall clock

AT89S51的串口程序，可以直接编译使用，标准程序(AT89S51 serial procedures, the compiler can directly use standard procedures)

STM32的GPS模块通过串口连接的实验，可以通过液晶显示GPS信息，包括精度、纬度、高度、速度、用于定位的卫星数、可见卫星数、UTC时间等信息。(STM32 GPS module via a serial connection test, you can display GPS information, including precision, latitude, altitude, speed, number of satellites for positioning, number of visible satellites, UTC time and other information through the LCD.)

单片机 C程序 介绍了cd4051模拟开关的使用方法(Microcontroller C CD4051 analog switch)

本程序是关于LED在单片机里的流水等的演示程序，已经经过测试(This program is on the LED in the SCM in the water and other presentation program, has been tested)

用stm32f103对ds1302时钟芯片进行读写，从而获得起内部的时钟数据(Read and write the DS1302 clock chip with STM32F103 to get the internal clock data)

亮度可调节LED灯，采用双色LED灯， LED调节亮度是通过调整通过它的PWM驱动电流大小得到的,节能灯一般是不能调整亮度的。本设计在项目中应用，绝对可以用。(Brightness can be adjusted LED lamp, using dual color LED lamp, LED adjust brightness by adjusting its PWM drive current size, energy saving lamps can not adjust brightness generally. This design is applied in the project, and it can be used absolutely.)

三星单片机资料比较少本程序实现S3F84U8看门狗-使能并喂狗(Samsung SCM relatively little information this program S3F84U8 Watchdog- enabled and feed the dog)

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.)
