Tiny Planet is small device connected to a GSM cell phone. When the mobile receives a predefined SMS (text message), like "Activate burglar alarm" or "Start backup pump", the circuit automatically recognizes it as a command, and switches the output port accordingly. Besides switching the port on or off, the user can pulse it for a short period (e.g. 鈥淩eboot remote server鈥?.

SOME BACKGROUND ON DESIGN PATTERNS The term “design patterns” sounds a bit formal to the uninitiated and can be somewhat off-putting when you first encounter it. But, in fact, design patterns are just convenient ways of reusing object-oriented code between projects and between programmers. The idea behind design patterns is simple-- write down and catalog common interactions between objects that programmers have frequently found useful.

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）。

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。

* 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.

It’s your first day in the lab.Undoubtedly you are experiencing a range of emotions: excitement, curiosity, anxiety. You will be working in this lab and with a group of people, as well as with your supervisor, for several years to come. This is the first day of a long commitment and, for some, a hard road ahead. Which is why it’s important to get off on the right foot.
