多频率门禁卡复制器程序

一线通讯，1线通讯，单片机实现例程，使用ASM开发，MAXIM公司onewire器件通讯例程！非常简洁！！PIC(MAXIM using ASM development company onewire routine communications device!)

it s aprogramming ic to be make remote control

This is a simple arithmatic code for 8051

1621-833-01.ASM的测试程序源代码(1621-833-01.ASM test procedures for source code)

用VHDL编写的串口通讯程序，包括几个不同的程序例子，也可以用verilog进行改写。()

微机原理与接口a/d转换，并口输出的汇编代码，用到8255可编程芯片(Microcomputer Principle and Interface a/d conversion, parallel assembly code output, programmable chips used in 8255)

说明：  学习资料，DSP实现FFT的实验报告，包括MATLAB实现FFT的代码，学习(Learning materials, DSP implementation of FFT experimental report, including MATLAB implementation of FFT code, learning)

单片机实验：跑马灯，通过移位的方式实现跑马灯的功能，程序非常简单(Single-chip experiments: Marquee, achieved through the translocation function of Marquee, the program is very simple)

说明：  用Proteus 和keil建立单片机仿真工程步骤(Proteus and keil to establish single-chip simulation engineering steps)

增强型单片机c8051f230与2.4G射频芯片所组成的无线通信系统，通过串口进行无线通信。文件内为汇编源程序。(C8051f230 with enhanced single-chip 2.4G RF chip which consists of wireless communication systems, through the serial port for wireless communications. Source file for compilation.)
