关于传感器的程序，请各位大侠给予指导，等

使用LPT口，模拟IIC，界面友好，使用方便，不失为一个硬件调试的好帮手！ 亦可透过IIC实现双机互连，因为IIC支持主从模式:-)-LPT I used to simulate IIC, friendly interface and ease of use, hardware debugging is a good helper! Through dual-IIC interconnection, as IIC support from the main mode :-)

c51 是经典的单片机，简单，精通51单片机，在学习其他的单片机 很易上手-C51 is a classic single-chip, simple, fluent in 51 single-chip, single-chip microcomputer in the learning of other very易上手

韦根解码程序,包括的原理图与KEIL C51原代码-Wiegand decoding procedures, including the schematic diagram with the original code KEIL C51

此程序为AD9850（DDS）直接数字频率合成器C语言源码。用125M的有源晶振，频率无失真输出可达到40M。该程序包括FYD12864LCD显示程序加4X4矩阵键盘扫描，可步进1M，1K，和任意频率输入。及相位设置。-This procedure for the AD9850 (DDS) Direct Digital Frequency Synthesizer C language source code. With 125M active crystal, the frequency output can be achieved without distortion 40M. The process includes the display program FYD12864LCD plus 4X4 matrix keyboard scanning, may be stepping 1M, 1K, and arbitrary frequency input. And phase settings.

12864液晶显示器的测试程序，汇编语言的，很有价值的！-12864 test procedures for liquid crystal displays, assembly language, and great value!

在有线电视中实现程控有源滤波器设计。为了充分利用设备和传输线,需要一种具有频率选择的网络―滤波器,将同一线 路上不同的信号分开,在电视机中也需要不同的滤波器(即选择有用信号,抑制无用信号) 。下面利用8051 单片机与12 位分辨率的DAC1208 数模转换芯片相结合的系统实现时间常数可程控有源滤波器设计,阐述了硬件结构与软件设计-In cable television in the realization of program-controlled active filter design. In order to make full use of equipment and transmission lines, the need for a frequency selective network- filter, the same lines separate different signal in the TV also requires a different filter (ie, choice of useful signals and suppress unwanted signals). Following the use of 8051 and 12-bit resolution digital-to-analog converter DAC1208 chip combining system time constant can be program-controlled active filter design, the hardware structure and software design

PIC16F877应用的AD转换主程序 并可以通过LCD显示-PIC16F877 applications AD conversion by the main program and LCD display

这是一个基于89C51单片机的简易信号发生器的源程序，程序代码由C语言编写-This is an 89C51 microcontroller based on the simplicity of the source signal generator, code written in C
