DirectX not only provides fast access to the hardware and therefore incredibly speedy performance, but it also makes it much easier for hardware developers to produce new devices that work well in the Windows environment. The DirectX APIs take away the necessity of writing your own low-level, device-specific code to access hardware such as the display adapter and network card, making it much easier for you to write programs that take full advantage of the computer s multimedia capabilities.

Summary Many control applications require converting some analog input to a digital format. The ADCINC12 User Module is a general-purpose, 12-bit analog to digital converter (ADC) that does just that. This Application Note is meant to be a simple introduction into its operation. The steps required to define, place, and write software are presented. Examples are developed in both assembly and C.

The market for miniature computer programming is exploding. C++ Footprint and Performance Optimization supplies programmers the knowledge they need to write code for the increasing number of hand-held devices, wearable computers, and intelligent appliances. This book gives readers valuable knowledge and programming techniques that are not currently part of traditional programming training. In the world of C++ programming, all other things being equal, programs that are smaller and faster are better. C++ Footprint and Performance Optimization contains case studies and sample code to give readers concrete examples and proven solutions to problems that don t have cut and paste solutions.

NAME Control_AT24Cxx This collection of routines allows an AT89C2051 microcontroller to read and write the AT24Cxx family of serial CMOS EEPROMS. This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051. Note that the minimum size of the buffer is determined by the page size of the AT24Cxx.

linux文件系統試驗 一、實驗目的 學習有關linux文件管理程序如何組織的知識，為簡化的文件系統設計并實現一組目錄操作。實驗中使用軟盤的fat12格式，設計一個程序可以對這種格式的磁盤進行一組目錄操作。 實驗使用了部分linux的系統調用，比如說open() sleek() read() write()幾個調用。通過此實驗來對linux的文件系統的管理有進一步的理解。 二、實驗要求 主要實現三個功能：一 讀取磁盤目錄的目錄列表。(命令輸入 ls ) 二 切換目錄（不處理路徑名）。（命令輸cd dir_name 或cd/ 或cd.. ） 三 刪除當前目錄下的文件。（命令輸入 del filename ）
