intel pxa255 处理器开发应用手册-Application Handbook

本系统分电压测量和信号产生输出两大部分，电压测量部分以模拟电路为主，配合放大模块、A/D转化模块、显示模块；通过凌阳单片机进行数据处理，在误差允许范围内显示测量电压值。信号产生以直接数字式频率合成器为核心，经过AT89S52对DDS芯片内部进行控制，使之输出标准正弦波形，利用编程实现频率预置、步进，达到电压输出频率的可调节步进。通过调试与测量完成了题目的基本部分和全部发挥部分的要求并有自己的创新。-Voltage measurement points of the system and the output of two major signals, voltage measurement circuitry to simulate the main part, with the amplification module, A/D conversion module, display module through Sunplus Single-chip data processing, in the range of error allowed shows the value of measuring voltage. Signal generated by direct digital frequency synthesizer for the core of the DDS chip AT89S52 after the internal control standards so that the output sine wave shape, frequency of use of pre-programming, step to the output voltage adjustable frequency step. Debugging and measurement, through the completion of the basic part of the topic and all the requirements to play a part and have their own innovation.

We intend to develop a wifi enabled p2p file sharing system on a linux platform using jxta and java. The purpose is to build a system that can be ported to an embedded device at a later stage and be used for p2p file sharing using the 802.11b standard. 我们旨在Linux平台上使用jxta 和java来开发一个支持wifi的p2p文件共享系统。其目的是建造一个以后可以移植到嵌入式设备的系统，使用802.11b标准进行p2p文件共享。 来源: http://sourceforge.net/projects/linux-p2p-wifi/-We intend to develop a wifi enabled peer-to-peer file sharing system on a Linux platform using JXTA and java.

一种纸币识别VC++程序源码，并含有多国纸币的特征库，如日元、英镑、港币...的特征库。有从纸币图像预处理、特征匹配的全过程

我有8051个做RTC，我得到的值从DS1307和显示时间和日期。这个小项目采用I2C protocol.just你连DS1307 8051 SCL，SDA，VCC，GND你会得到准确的值。

应用背景STM32 STM32 开发板自带了一颗非常强劲的MP3解码芯 片，利用该芯片我们可以实现 MP3/OGG/WMA/WAV/FLAC/AAC/MIDI等各种音频 文件的播放。关键技术本章实验功能简介：开机先检测字库是否存在，如果检测无问题，则对VS1053进行RAM测试和正弦测试，测试完后开始循环播放SD卡MUSIC文件夹里面的歌曲（必须在SD卡根目录建立一个MUSIC文件夹，并存放歌曲在里面），在TFTLCD上显示歌曲名字、播放时间、歌曲总时间、歌曲总数目、当前歌曲的编号等信息。KEY0用于选择下一曲，KEY2用于选择上一曲，WK_UP和KEY1用来调节音量。DS0还是用于指示程序运行状态，DS1用于指示VS1053正在初始化。
