在大多2440開發板BSP中的SMDK2440\DRIVERS\backlite目錄下一般都有背光驅動。在注冊表中添加如下函數的時候，開機時確實可以打印"!!!!!!!!!!!! BACKLIGHT ON !!!!!!!!!!!!，如果沒有操作大概1分鐘后也可以打印!!!!!!!!!!!! BACKLIGHT OFF !!!!!!!!!!!!。但打印("!!!!!!!!!!!! BACKLIGHT OFF !!!!!!!!!!!!后，就算有觸發事件（在觸摸屏上點擊，或者移動鼠標）也不會打印"!!!!!!!!!!!! BACKLIGHT ON !!!!!!!!!!!!。 其實這個驅動大體是正確的，只是當鍵盤鼠標或觸摸屏輸入時候gwes 發送“PowerManager/ActivityTimer/UserActivity” event，而不是原驅動中的“("UserInputEvent") ”修改后的源程序如下（SMDK2440\DRIVERS\backlite目錄下bak_hw.cpp文件）。

RS_latch using vhdl, When using static gates as building blocks, the most fundamental latch is the simple SR latch, where S and R stand for set and reset. It can be constructed from a pair of cross-coupled NOR (Not OR) logic gates. The stored bit is present on the output marked Q. Normally, in storage mode, the S and R inputs are both low, and feedback maintains the Q and Q outputs in a constant state, with Q the complement of Q. If S (Set) is pulsed high while R is held low, then the Q output is forced high, and stays high when S returns to low similarly, if R (Reset) is pulsed high while S is held low, then the Q output is forced low, and stays low when R returns to low.

After decades of war one company, who had gained powerful supplying both sides with weaponary, steps forwards and crushes both warring factions in one swift movement. Using far superior weaponary and AI craft, the company was completely unstoppable and now no one can stand in their way. Thousands began to perish under the iron fist of the company. The people cried out for a saviour, for someone to light this dark hour... and someone did.

軟件思路：選擇RAO做為模擬輸入通道 連續轉換4次再求平均值做為轉換結果最后結構只取低8位結果送數碼管的低3位顯示 硬件要求：撥碼開關S14第2位置ON，第1位置OFF撥碼開關S6全部置ON，S5第4-6位置ON，第1-3位置OFF為不影響結果，其他撥碼開關置OFF。

Quartz is a full-featured, open source job scheduling system that can be integrated with, or used along side virtually any J2EE or J2SE application - from the smallest stand-alone application to the largest e-commerce system. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs jobs whose tasks are defined as standard Java components or EJBs. The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and clustering. Quartz is freely usable, licensed under the Apache 2.0 license.

* 程序描述描述: * * 程序分兩大部分，當開發板上電的時候撥碼開關的第一位是閉合（ON）的狀態 * * 運行LOOP1循環，矩陣鍵盤有效，數碼管顯示按鍵值，同時將按鍵值通過串口發* * 送出去。 * * 當開發板上電的時候撥碼開關第一位是打開的(OFF)的狀態，則獨立鍵盤有效 * * 按下K1則逆時針點亮數碼管的每一段，按下K2鍵則順時針點亮數碼管的每一段 * * 同時將當前點亮數碼管的數據通過RS232串口發送出去。

Some time ago, I stated in another article that I d take the idea of location broadcasting and develop a mobile solution as a follow-up. The problem back then was I had no means to get location data off of a cell phone, or a way to make it useful. My, how times have changed since then! In this article, I ll demonstrate how to get your phone s GPS coordinates…

A programmable digital signal processor (PDSP) is a special-purpose microprocessor with specialized architecture and instruction set for implementing DSP algorithms. Typical architectural features include multiple memory partitions (onchip, off-chip, data memory, program memory, etc.), multiple (generally pipelined) arithmetic and logic units (ALUs), nonuniform register sets, and extensive hardware numeric support [1,2]. Single-chip PDSPs have become increasingly popular for real-time DSP applications [3,4].

Hibernate: A Developer s Notebook shows you how to use Hibernate to automate persistence: you write natural Java objects and some simple configuration files, and Hibernate automates all the interaction between your objects and the database. You don t even need to know the database is there, and you can change from one database to another simply by changing a few statements in a configuration file. If you ve needed to add a database backend to your application, don t put it off. It s much more fun than it used to be, and Hibernate: A Developer s Notebook shows you why.
