相信大大家都用过DS18B20A，我自己也用手写了个玩玩(Believe that we all used DS18B20A, I have to play with a hand-written)

超声波测距，能够实现汽车防撞系统超声波的测距，完全由51单片机控制(Ultrasonic Ranging)

一个电表行业专用的基于645规约的电表485通讯抄表程序，可以进行485总线抄表，645规约测试。程序技术要点就是规约数据传输协议的处理，如向电表发送数据时的控制码和数据长度、发送的数据部分(数据标识 + 密码 + 数据)、应答帧长度、结束标志等通讯协议的处理值得大家学习。(A meter-based industry-specific statute 645 meter 485 meter-reading procedure can be carried out 485 meter, 645 Statute of the test. Procedures for the technical elements of the statute is to deal with data transmission protocols, such as sending data to the meter when the control code and data length, send the data section (data logo+ Password+ Data), response frame length, marks the end of the treatment protocol, etc. everyone deserves to learn.)

基于最小冗余线阵的谱相关共轭循环MUSIC算法(MUSIC algorithm based on conjugate cyclic spectral correlation minimum redundancy linear arrays)

使用DataAdapter对数据库进行操作 将SQL-search.aspx程序可改为使用DataAdapter对数据库进行操作. 程序使用"Dim objAdapt As New OleDbDataAdapter(strcmd,objCon)"创建了DataAdapter对象。(Use DataAdapter to operate the database The SQL-search.aspx program can be changed using the DataAdapter to operate the database. The program uses "Dim objAdapt As New OleDbDataAdapter (strcmd, objCon)" Creating a DataAdapter object. )

MICROSOT 做ACTIVE MOVE FLASH的东东,此说明是其SDK的一部份(MICROSOT make the ACTIVE MOVE FLASH Dongdong, this note is a part of its SDK)

一台安捷伦的N9020A频谱分析仪，所带的例子是GPIB连接的，现在用LAN来连接。 (Agilent N9020A spectrum analyzer, the example brought to GPIB connection, use the LAN to connect.)

液晶240*128驱动 用的是PIC单片机 但是可以改 51单片机 里面驱动都一样 就是 拿过来就可以用 (LCD 240* 128 drive using a PIC microcontroller, but can be changed inside the microcomputer 51 is to take over the same driver can be used)

单玉米 多目录 绑定转向 win32 sdk开发(single directory bundled with more corn to the development of win32 sdk)

本总体方案完成国标GB20600-2006数字电视地面广播传输系统基带部分功能。 输入数据码流经过扰码器（随机化）、前向纠错编码（FEC），然后进行比特流到符号流的星座映射，再进行交织后形成基本数据块，基本数据块与系统信息组合（复用）后并经过帧体数据处理形成帧体，帧体与相应的帧头（PN序列）复接为信号帧（组帧），经过基带后处理转换为输出信号（8MHz带宽内）。该信号经变频转换为射频信号（UHF和VHF频段范围内）。用C程序设计了图形交互界面，可以在界面上直接设置调制参数。(The overall program completion GB GB20600-2006 digital terrestrial television broadcasting transmission systems baseband function. The input data stream through the scrambler (randomization), forward error correction (the FEC), then the symbol constellation mapping bitstream to the stream, and then after forming the basic block interleaving, the basic data block and information combined system ( multiplexing) after data processing and after the frame body forms a frame body, frame body with a corresponding header (PN sequence) multiplexed signal frame (framing), after post-processing baseband signal is converted to an output (internal 8MHz bandwidth). The signal is downconverted to a radio frequency signal (in the VHF and UHF frequency range). C program designed graphical interface, you can set modulation parameters directly on the screen.)
