项目16 基于单片机LCD数字测速仪的设计 使用C++程序编程(Item 16 LCD digital speedometer on chip design using C++ programming)

ARM程序，实现了SPI通信协议，可用于任何使用SPI通信协议的器件上，在LPC2103上测试成功。(ARM procedures realize the SPI communication protocol, can be used for any use of SPI communication protocol on the device, tested successfully in the LPC2103.)

WSN的GAF算法程序针对无线传感器网络节点部署密集的特点，提出了 GAF 算法。在 GAF 算法中，根据节点的地理位置信息和节点的无线电发射半径（radio range），传 感器网络部署区域被划分为虚拟单元格（virtual gird）。根据自己的物理位置信 息，各个节点被划入到自己的单元格中。各个节点的物理位置信息可以由 GPS 或 其它定位系统得到。 (GAF algorithm of WSN deployment intensive features for wireless sensor network node, proposed GAF ​ ​ algorithm. In GAF algorithm, the radius of the radio transmitting node and the node' s location information (radio range), the sensor network deployment area is divided into a virtual cell (virtual gird). According to their physical location information, each node is classified into its own cell. The physical position information of each node can be obtained by the GPS or other positioning systems.)

用于数字电话号码键盘的解码，采用goertzai的方式，希望对您有用(For digital phone number keyboard decoding, using the goertzai way and hope to be useful to you)

白噪声发生器，利用白噪声发生器产生白噪声。白噪声发生器，可以调制幅值，频率，相位。白噪声发生器，是一款很好的发生器。(White noise generator, the use of white noise generator white noise. White noise generator, can be amplitude modulation, frequency, phase. White noise generator, is a very good generator.)

自动车坐标模块，结合码盘，陀螺仪使用，定位精度一mm(Automated vehicle coordinate module, combined with the code disc, gyroscope use, the positioning accuracy of a mm)

设计并制作用于电池储能装置的双向DC-DC变换器，实现电池的充放电功能，功能可由按键设定，亦可自动转换。(A bidirectional DC-DC converter for battery energy storage is designed and implemented to realize battery charging and discharging functions. The functions can be set by the button and also can be automatically converted.)

DDS9850，亲测可用，有中文解释，信号发生器(DDS9850, pro-test is available, there are Chinese explanation, the signal generator)

基于Proteus环境进行8086 CPU汇编语言程序设计的源代码，包含经典的红绿灯控制，循环与分支程序设计(Based on Proteus environment 8086 CPU assembly language programming source code, including the classic traffic light control, circulation and branching program design)

一份，NRF905的开发程序，在使用时，需根据自己的要求修改(A, NRF905 the development of procedures, in use, the need to modify according to their own requirements)
