资源描述在这个项目中你将驱动7段LED得到VHDL逻辑的一些信息。 ；你知道当我们激发一些引脚7段输入它的一些LED转向等展示一些东西比如 ；。关于7段和驱动器的更多信息，你可以读取数字逻辑与计算机设计莫里斯马诺。

这段代码是使用 xilinx spatan 3e 董事会开发的 vhdl 程序赛车。 EDK 平台上开发了此代码，它具有以下模块 1.Buttons_4bit 2.时钟发生器 3.调试模块 EDK 是从 xilinx 的 emebedded 开发套件平台，它现在作为 vivado 在以后的版本中被改变。

关于USB的相关芯片的应用说明，很不错的-USB chip on the relevance of the application notes, very good

我用BASIC开发环境下的LED屏单显示实验程序，可以初步了解下B环境下SPI的简单应用-I use BASIC development environment under a single LED screen shows the experimental procedure, can be a preliminary understanding of B under the simple application of SPI

目前国内有关数字信号处理的教材在讲解快速傅里叶变换（FFT）时，都是以复数FFT为重点，实数FFT算法都是一笔带过，书中给出的具体实现程序多为BASIC或FORTRAN程序并且多数不能真正运行。鉴于目前在许多嵌入式系统中要用到FFT运算，如以DSP为核心的交流采样系统、频谱分析、相关分析等。本人结合自己的实际开发经验，研究了实数的FFT算法并给出具体的C语言函数，读者可以直接应用于自己的系统中。--I implemented FFT algorithm in real number and provides a C function. Users could use it directly in their systems.

本文介绍了红外多路遥控系统。红外多路遥控系统可实现16路的红外开关控制。以码分制多通道红外遥控为设计的基本思路。通过键盘及代码生成电路、编码、脉冲调制振荡和红外发射构成红外发射电路。通过红外接收，解码以及由单片机控制的医码控制电路组成红外接收电路。-The passage has introduced the nfrared multichannel system of remote control. The infrared multichannel system of remote control can realize the infrared switch control of 16 roads. With yard divide into system the basic train of thought with much passageway infrared remote control of design. Through keyboard and code generation circuit, coding and pulse modulation vibration with infrared project to form infrared project circuit. Pass infrared take over , decode as well as the medical yard control circuit composition that controled by single flat machine are infrared to take over circuit.

用端口模拟的IIC程序,可以在没有IIC总线的芯片使用.C语言编辑,可以任意移植到其它的芯片.该程序在freescale芯片测试通过-IIC with the port simulation program, you can not use the IIC bus chips. C language editor, can be ported to any other chips. The program freescale chip test

韩国三星公司的arm 2410 的usb驱动代码，对于想开发ARM调试工具的工程师，可能有帮助-Korea"s Samsung Corporation arm of the 2410 usb driver code, For development to debugging tool for ARM engineers, may help
