DJGPP DOS 版的 32-bit C/C++ compiler

"compiler及其環境在附件只能在windowsXP DOS command下建立"

安裝步驟

請至 djgpp web side 相對應的目錄下尋找本文中提到的檔案.
先在您的硬碟上(假設您欲安裝至 C 槽)建立一子目錄為 djgpp, 即 mkdir c:\djgpp, 並將之後所下載的檔案皆放置在該目錄下.

U-Boot Source Code

Das U-Boot Source Code

• The current source code is available through the git repository at git.denx.de.
• Released Versions (and some special snapshots) are available from the DENX FTP server
• Snapshots are available using the clever "snapshot" feature of the git server (see the "snapshot" link after all commit entries).
  NOTE: even though the download will be a bzip2 compressed tarball, and the file on your disk will be named "*.tar.bz2", you may find that it's actually not compressed at all. This is a "feature" of your web browser, and we cannot do anything to help it.
• www.denx.de also hosts the Custodian git trees
• CVS is no longer supported.
• The old project page at SourceForge is no longer used and dead.

Symbolic Circuit Analysis

Symbolic Circuit Analysis using matlab  (http://ricknewby.blogspot.tw/)

Lately I’ve been working on ways to integrate Matlab and Spice simulation. While I was browsing Matlab file exchange I ran into some rather fascinating software. It’s called SCAM, which stands for Symbolic Circuit Analysis in Matlab. This a Matlab script that provides symbolic solutions to circuits; it works with resistors, capacitors, inductors and opamps.

簡介Doxygen

作者：Gary W. Lee

什麼是Doxygen? Doxygen效果?

Doxygen 是一個程式的文件產生工具，可將程式中的特定註解轉換成為說明文件。通常我們在寫程式時，或多或少都會寫上註解，但是對於其他人而言，要直接探索程式裡的註解，與打撈鐵達尼號同樣的辛苦。大部分有用的註解都是屬於針對函式，類別等等的說明。所以，如果能依據程式本身的結構，將註解經過處理重新整理成為一個純粹的參考手冊，對於後面利用您的程式碼的人而言將會減少許多的負擔。不過，反過來說，整理文件的工作對於您來說，就是沈重的負擔。

SPI, Microwire I2C 協定格式

Interfaces: SPI, Microwire and I²C Protocol Formats

By Volker Soffel

MicroController Pros Corporation 

This article is part 2 in a series about various microcontroller communication interfaces. In part 1 of the series, I discussed some typical applications and implementations of the SPI, Microwire and I2C interfaces. I looked at their general differences, basic features, advantages and disadvantages.  In this part, I'll cover the specifics of their protocol formats. In Part 3 we will start to take a closer look at asynchronous interfaces (UART based RS232C/RS485/LIN, CAN, USB and Ethernet).

都是軟體問題惹的禍？

    大學畢業取得電腦工程學士學位後，我曾在一家線鋸公司擔任軟體開發人員。多年來，這些線鋸產品不定時地會發生一些鋸線從鋸片上脫落的問題，但大家都一直認為這問題並不嚴重。直到有一天，公司決定打造更大且具有更多切割軛的新款線鋸。
