多路巡回检测，已成功调试，12887芯片制作，51单片机编程

开发环境ADS， 直流电机控制实验 掌握使用PWM方式控制直流电机的转动速度。-Development Environment ADS, DC motor control experiment to master the use of PWM control of DC motor rotation speed.

这个是用AVR编写的程序，这里是一个时钟电路，用数码管显示当前时间。对初学者比较有用。-This is prepared by AVR process, here is a clock circuit, a digital display the current time. More useful for beginners.

原创的XML解析，不过只能解析节点及节点内容，不支持属性，纯C语言，适合嵌入式系统使用。-Original XML parsing, but only parse the contents of nodes and the node does not support attributes, pure C language, suitable for embedded systems.

An "improved" inductance / capacitance meter Actually, it works much the same as the originalIt differs from the original in that: A 16F628 PIC is used. This has internal comparator, which means the LM311 is no longer needed.Software calibration is used. The finished meter can be calibrated against "any" accurate capacitor within the range 100pF to about 10000pF -An "improved" inductance/capacitance meter Actually, it works much the same as the originalIt differs from the original in that: A 16F628 PIC is used.

51单片机C语言编程手册，由周立功发布，详细介绍了51的硬件与C编程-51 Single-chip C language programming manual, by the week Ligong released details of 51 hardware and C programming

C8051F020单片机的AD测试程序，很好的哦！直接移植便可啦！-C8051F020 MCU AD test procedure, Oh good! Transplant will be able to direct it!

单片机计时仪器，不错的参考程序。接口可以自行修改即可-Single-chip timing equipment, a good reference for the procedure. Interface can be modified to

C51写的串口编程的范例，写串口的兄弟可以参考！-C51 write serial programming paradigm, write serial port can refer to the brothers!

一个简单的计算器是如何写的，单片机可以做很多智能东西，学习着可以发挥自己的想想，自己动手做一做。-A simple calculator is how to write, single-chip microcomputer can be a lot of smart things to do, learning to play with their own think about to do one to do it yourself.

让数码管的亮度一致,原代码是运行在AT89S52上,12MHz-The brightness of the digital control line, the original code is run on AT89S52 on, 12MHz
