还不错的LCD点阵提取程序,提供一些基本图案.-Dot matrix LCD is also good extraction procedures, to provide some basic patterns.

485单相电能表开发程序，液晶显示。采用AD7755设计，可与掌上电脑连机通信设置各种电能表参数。-485 single-phase energy meter development process, liquid crystal display. Design using AD7755 can be connected Pocket PC communication settings of various parameters of energy meter.

HID usb设备的单片机固件程序，能自己用单片机控制鼠标。-HID usb device microcontroller firmware to control their mouse using single-chip microcomputer.

一种单片机双工无线串行传输方案,格式为ｗｏｒｄ-A single-chip wireless duplex serial transmission program, the format for word

具体的硬件结构,大家可以看 WS 系列产品的原理图 * 利用AT89S51单片机来制作一个手动计数器，在AT89S51单片机的P3.3管脚接一个轻触开关， * 作为手动计数的按钮. 数码管驱动采用动态扫描方式用单片机的P0.0－P0.7驱动数码管的段码， * P1.3 控制个位数码管的共阳极公共端，P1.2 控制十位数码管的共阳极公共端 * 通过按一下P3.3按键,数码管做 1 的累加, 实现00~99的计数功能,当计到99时又从00开始. * 大家可自行修改程序,扩展到0000~9999的计数范围-Specific hardware architecture, we can look WS schematic family of products using AT89S51* Single-chip to produce a manual counter, in the P3.3 pin MCU AT89S51 by one touch switch,* as a manual count of button. nixie tube driven by dynamic scanning with MCU P0.0-P0.7 driver code segment digital tube,* P1.3 control bit digital tube anode of a total public client, P1.2 control of 10 digital total anode tube through public client* P3.3 click buttons, a digital pipe to do one of the cumulative, realize 00 ~ 99 count function, when the total to 99 from 00 the beginning of time.* everyone can modify the program, extended to 0000 range of ~ 9999 count

在外部环境中检测亮度，温湿度，其中带232及485控制-Detected in the external environment brightness, temperature and humidity, which with 232 and 485 control

这是用192*64液晶实现的波形液晶显示。用的液晶型号是OCMJ4*12B，这是用正弦函数显示的。-This is 192* 64 LCD LCD waveform to achieve. LCD model is used OCMJ4* 12B, which is shown by sine function.

本程序主要通过外部中断INT0及3.3端口读取PS2键盘值并通过LCD1602显示，键扫描码的解码通过数组方式解码，程序的解码功能主要针对数字及大小写字母和常用标点符号 硬件描述：PS2键盘的时钟线（clk）接89S51的INT0（P3.2）,数据线data接（P3.3） LCD的控制端口分别为： RS = P2^7，RW = P2^6，EP = P2^5，数据端口为P0，液晶显示偏压VL必须接 -This procedure mainly through external interrupt INT0 and 3.3 read PS2 keyboard port value through LCD1602 display, key scan code decoder way through an array of decoding, the procedure for decoding function of the major figures and upper and lower case letters and punctuation marks commonly used hardware description: PS2 keyboard clock line (clk) then 89S51 the INT0 (P3.2), data lines data access (P3.3) LCD control port, respectively: RS = P2 ^ 7, RW = P2 ^ 6, EP = P2 ^ 5, data ports for the P0, LCD bias VL must be received
