Designing Embedded Hardware Ebook By John Catsoulis If you want to build your own embedded system, or tweak an existing one, this invaluable book gives you the understanding and practical skills you need.

单总线多点测温系统，单总线它采用单根信号线既传输时钟又传输数据，而且数据传输是双向的它具有节省I/O 口线资源结构简单成本低廉便于总线扩展和 维护等诸多优点。本系统中所有的DS18B20都接在单片机的P1.1口上。用一个液晶屏显示，从单片机P3口接上8个开关，与右边的DS18B20 编号对应。当没有开关按下时屏幕显示"which NO ...

Here are the functions for Hamming code 7.4 and Extended Hamming code 8.4 encoding and decoding. For 7.4 code, one error per 7-bit codeword can be corrected. For 8.4 code, one error per 8-bit codeword can be corrected and not less than 2 errors can be detected.

This book brings together indispensable knowledge for building efficient, high-value, Linux-based embedded products: information that has never been assembled in one place before. Drawing on years of experience as an embedded Linux consultant and field application engineer, Christopher Hallinan offe ...

pHash is an implementation of various perceptual hashing algorithms. A perceptual hash is a fingerprint of an audio, video, or image file that is mathematically based on the audio or visual content contained within. Unlike cryptographic hash functions that rely on the avalanche effect of small chang ...

A Convex Hull is the smallest convex polygon that contains every point of the set S. A polygon P is convex if and only if, for any two points A and B inside the polygon, the line segment AB is inside P. One way to visualize a convex hull is to put a "rubber band" around all the points, and let it wr ...

I ll probably write up a short article next week outlining how the ActionScript works, so people can modify it, and work with it more easily in Flex. You can download the component and source code here. There are some instructions in the FLA on how to use it. Note that this is not a compiled compo ...
