Epson 150II点阵式打印机电路原理图,PCB图,有四个版本,CPU有LPC764,89C51RD2等,有驱动宽度保护功能.-Dot-matrix printer Epson 150II circuit schematics, PCB diagram, there are four versions, CPU has LPC764, 89C51RD2 and so on, have driven the width of protection.

PC数字电压表的设计,原理图以及代码,设计文档.此数字电压表的优势在于可以通过串口将测量所得到的电压值传给PC机,这样的话有利用整个数据的采集与分析.上位机采取的是串口通信软件.-PC digital voltage meter design, diagram and code, Design Documentation. This figure voltage meter advantage is through the serial port will be measured by the voltage transmission PC, so is the use of the entire data collection and analysis. PC"s serial port communication software.

AVR library for IR communication.

：章介绍了数据采集系统中STC12系列单片机与PC机之间的串行通信。设计了sTc12c2052AD 与 MAX232的硬件电路，使用汇编语言编程，设置了串行1：7的工作方式，相应的波特率计算方法及特点，发送并接 收数据。单片机从EEPROM 中读取数据，通过R．S-232将其传入PC，并将数据存储在24C02中。-: Chapter introduces data acquisition system STC12 Series MCU and PC serial communication between machines. Designed sTc12c2052AD with MAX232 hardware circuit, the use of assembly language programming, set up the way the work of serial 1:7, the corresponding baud rate calculation method and the characteristics of sending and receiving data. Single-chip EEPROM read data from, by R. S-232 to incoming PC, and data storage in the 24C02.

51程序库，一些例，学51单片机的基础用，-51 libraries, a number of cases, learning the basis of single-chip microcomputer 51, and

通信方式是485方式。通过485来控制一组灯的开关。-485 are way communication. Through 485 to control a group of light switches.

此程序为利用mage8 AVR 和EM4094实现读取ISO15693类型卡的C程序、读卡稳定、这个项目我们做了好久、非常不错的程序、很适合做这方面产品的朋友们参考-This procedure for the use of mage8 AVR and EM4094 achieve ISO15693 type of card reader C procedures, reader stability, the project we have done for a long time, very good program, it is suitable for products in this area refer to my friends

基于MCS- 51 单片机的洗衣控制系统, 控制面板由按键、指示灯和LED 显示器组成。 按键选择洗衣机工作方式, 指示灯配合按键工作, LED 显示器则显示洗衣机洗涤和脱水时 间。洗衣机的整体电路模块包括键盘矩阵、指示灯、电动机控制及电源电路。控制程序设计 包括定时中断服务程序、外中断服务程序及主程序。-Based on MCS-51 SCM laundry control system, control panel by the button, LED indicator light and display components. Button to choose washing machines work, light work with the button, LED display shows time washing machine washing and dehydration. Washing the overall circuit module includes a keyboard matrix, light, motor control and power circuit. Control program design includes interrupt service routine from time to time, outside the interrupt service routine and the main program.
