计程车计费（C语言编程、按键、12864液晶显示）

在stm32的cpu上移植freertos操作系统，程序在freertos基础上实现了，按键扫描，led灯控制，串口收发处理，定时器中断程序等功能。使用MDK打开工程文件即可。(Stm32 on the cpu transplant freertos operating system, the program freertos based on realized, key scan, led lamp control, serial port transceiver processing, function timer interrupt procedures. MDK can open the project file.)

练手用写的，就当参考吧，不算成熟，分享给大家参考用。分客户端和服务器端两部分，各取所需吧！如果要发布产品，仍需要做大量工作。

C# 模拟网页实现跨平台Post提交，相信有很多人都有过类似的经历，想实现程序的自动提交，并且跨平台，其实这个很简单的

基于使stm32F103芯片，可以显示不同频率的正弦波形(Sinusoidal waveforms with different frequencies can be displayed)

一种时频域联合捕捉主动声纳信号的方法.介绍了一种可应用于被动声纳的时频域联合捕捉主动声纳信号的方法及其工作流程。仿真相同噪声环境下使用该方法的发现距离与主动声纳探测距离,仿真结果表明使用该方法的发现距离远超过主动声纳探测距离,使用该方法可实现对目标的远程发现。(A time-frequency domain joint capture of active sonar signals. Introduced passive sonar, which can be applied when the frequency domain joint to capture active sonar signal its workflow. The discovery of the method used in the simulation of the same noise environment distance active sonar detection range, simulation results show that using the method found distance than active sonar detection range, the use of this method can be found remote target.)

TI C66X DSP上H264编解码例程，对学习C6678和相关的工程技术人员，有非常重要的参考作用，非常值得下载。(C66X DSP H264 on TI encoding and decoding routines, learning C6678 and related engineering and technical personnel, has a very important reference role, it is worth downloading.)
