PROTEL 99SE快速入门指南，是初学者的良师益友。-PROTEL 99SE Quick Start Guide is a mentor for beginners.

介绍单片机外围电路设计的一本基础书，做电子设计的朋友不可或缺的资料。-Introduced single-chip peripheral circuits design based on a book, to do electronic design information indispensable friend.

S3C44B0扩展16C554串口，包括原理图和源码 原来上传过源码，看到很多人下载，考虑到下载者阅读方便，所以这次增加了原理图。-16C554 serial S3C44B0 expansion, including schematics and source code uploaded the original source, to see a lot of people to download, taking into account that those who download the ease of reading, so the increase in schematics.

好东西，大家快来下，值得一看的东西，受益匪浅

基于C51的MP3原理图。同学做了很久的。内有电路图。仅供参考。做得很烂。多多包涵。-based on the C51 MP3 schematics. Students do for a long time. Within circuit. For reference purposes only. Do poor-quality. Bear with me.

51系列单片机指令列表，非常详细，对新手有帮助，-51 Series MCU instructions list is very detailed and helpful to newcomers,

数字温度计进而考虑到用温度传感器，在单片机电路设计中，大多都是使用传感器，所以这是非常容易想到的，所以可以采用一只温度传感器DS18B20，此传感器，可以很容易直接读取被测温度值，进行转换，就可以满足设计要求。-Digital thermometer to take into account the use of temperature sensors, in single-chip circuit design, most of them are the use of sensors, so it is very easy to think of, so can use a temperature sensor DS18B20, this sensor can easily be directly read measured temperature values, the conversion, it can meet the design requirements.

这是参加电子设计大赛时的作品：红外遥控小车：用红外线通过一块AT89S52单片机发射信号即编码，并用红外接收头接收信号；接着再用另一块AT89S52单片机对红外发射出的信号编码进行解码，最后再用一块AT89S52单片机用解码所得码值编写程序后驱动步进电机。步进机功能启动后不仅能使受控小车向前后左右四个方向前进和转弯，而且还能控制小车再地上转动并留下方形或圆形等形状。-This is the time to participate in Electronic Design Contest works: infrared remote control car: Using infrared transmission signal through an AT89S52 microcontroller that is encoded and used infrared receiver to receive the first signal and then using the other an infrared emitting MCU AT89S52 code and decode the signal and finally an AT89S52 microcontroller then proceeds with the decoding key value of the preparation of procedures to drive a stepper motor. Stepper machine function activated not only make the car forward in a controlled direction and after about four turns, but also to control the car and then turned and left the ground such as square or round shapes.
