Perl and XML
XML is a text-based markup language that has taken the programming world by storm. More
powerful than HTML yet less demanding than SGML, XML has proven itself to be flexible and
resilient. XML is the perfect tool for formatting documents with even the smallest bit of
complexity, from Web pages to legal contracts to books. However, XML has also proven itself to
be indispensable for organizing and conveying other sorts of data as well, thus its central role
in web services like SOAP and XML-RPC.
As the Perl programming language was tailor-
Small calculater GUI
This GUI takes 2 user chosen numbers and applies a matchmatical operation on the two numbers. Also shows save and load functionality.
Small RTOS51是為51系列單片機而編寫的。它是完全免費的、源代碼公開的多任務實時操作系統。它可在無任何外部數據存儲器的單片80C51系統上運行，并且是可移植的。全書分兩部分。第一部分為基礎篇，介紹Small RTOS51和一些基本概念，并詳細分析Small RTOS51的工作原理。第二部分為應用篇，給出部分常用硬件在Small RTOS51下驅動程序的源代碼。這些源代碼已在DP51單片機仿真實驗儀上全部調試通過，且只要經過很少的改動，或是不改動，就可以在其他環境下使用。應用篇還通過對這些源代碼的分析，讓讀者理解基于RTOS的編程方法，并給出完整的例子讓讀者全面掌握基于RTOS的編程方法。本書可以作為高等院校相關專業的課程教材、實驗參考資料或課外讀物，對嵌入式應用開發人員也有重要的參考價值
