介绍了ATMEGA128的AD使用，很详细，值得一砍，不过是E文的-ATMEGA128 introduced the use of the AD, in great detail, it is worth a cut, but the text is E.

这是本人最近几年所编写的串行通讯的代码集，可以供大家参考学习。-recent years prepared by the serial communication code sets, we can reference for learning.

基于中断控制的声光报警器的设计.采用中断方式，设计一个声光报警器的硬件电路和控制程序。程序运行时，一旦8位开关信号量状态满足设定条件，就触发中断，使发光二级管按规律闪烁，同时扬声器播放一段音乐。 硬件设备包括一台微机、一个MFID微机实验箱、一块T型板，2输入四与门 74ls08、8位总线驱动器 74ls245、LM386A音频放大器、排阻、扬声器各一个，发光二极管8个，470uF电容2个、104电容4个，插线若干。 -Interrupt-based control of sound and light alarm design. Using interrupt mode, designing a sound and light alarm hardware circuits and control procedures. The program is running, once the 8-bit switch signal to set the amount of state to meet the conditions to trigger interrupts, so that light-emitting diode flashes according to the law, while speakers play a piece of music. Hardware includes a computer, a computer simulation, MFID box, a T plate, 2 input 4 and gate 74ls08, 8-bit bus driver 74ls245, LM386A audio amplifier, exclusion, speakers of a light-emitting diode 8, 470uF capacitor 2 a, 104 capacitors 4, plug-line number.

一款操作128x64 图形液晶显示屏的完整 C51 程序，里面有关于汉字及图形的显示程序-A 128X64 graphic LCD screen to operate the complete C51 procedure, which has on the characters and graphics display program

avr的ad转换程序例子，在ouravr上面还有很多好的入门例子程序-avr conversion examples in ouravr above there are many good examples of entry procedures

DIY多功能转换器（已调试通过）。 本原理图可以实现USB/RS232、USB/RS422、USB/RS485接口转换功能。只需安装USB驱动程序即可实现USB转串口的功能，简单方便。另外只需对电路图稍作改动即可实现RS232/RS422或RS232/RS485转换功能。 心动了吗？不如赶快行动，拥有属于自己的五合一的接口转换器吧！-DIY Multi-function Converter (has debug through). The schematic diagram can be achieved USB/RS232, USB/RS422, USB/RS485 interface conversion. Simply install the USB driver can achieve the function of USB to serial, easy and convenient. Also just to make a minor amendment to the circuit can be realized RS232/RS422 or RS232/RS485 conversion. Echocardiography it? Action as soon as possible, with their own-one interface converter吧!
