用于水文频率计算的目估适线法,程序基于φ值表查询计算(Mesh used to calculate estimates of hydrological frequency fitting method)

用Visual C++ 6.0实现的一个VSP程序。包你看后受益匪浅。(with Visual C 6.0 of a VSP procedures. After looking at the package you benefited.)

一个简单的小车单片机C语言控制，适合初学者(A simple car microcontroller C language control, suitable for beginners)

基于VC++的，以操作文件的方式（CreateFile,WirteFile,ReadFile）来操作串口实现的射频卡门禁系统，实现了包括读卡写卡，寻卡防冲突等功能。(Based VC++ in order to manipulate papers (CreateFile, WirteFile, ReadFile) to operate the serial interface of the RF card access control systems, including the realization of the card reader to write, look for cards anti-collision function.)

本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)
