探訪Windows CE LED驅動程式

當您利用Visual C++來建立Windows CE作業系統(OS Design)專案時，在PLATFORM目錄下有廠商所提供的驅動程式，以本範例為例，在DMA2440XP的src\driver目錄下，存放著廠商所提供的驅動程式，我們以LED為例，開啟LED.c檔案，您可以看到主函式DllMain()，這是因為驅動是以DLL的型式出現。

下圖為驅動的裝載及缷載函式，在裝載函式中會呼叫InitLedAdr()及GPIOInit()兩函式進行初始化作業。

以下是這兩個函式及全域變數的列表


以下是開啟及關閉函式。

產生第一個Win CE程式並上載到DMA2440

1. 啟動Visual studio 2005開始撰寫程式
2.選擇File功能表建立新專案

3.選擇Smart Device 及 Win32 Smart Device Project

4.按下執行鈕

5. 選擇yes

6. 找到執行檔 (注意路徑), 並複製

7.開啟瀏覽裝置

8. 複製到Temp目錄

9. 最後您可以打開平台上的檔案管理程式去執行程式

安裝ActiveSync驅動程式

1.把DMA2440上的USB熱插拔一下, 安裝ActiveSync USB驅動程式(注意和DNW驅動不同)

2. 安裝ActiveSync軟體

如何在DMA2440上燒Win CE作業系統

1. 啟動DNW(記得要將RS232的連接線接上)
2.設定通訊速率
3.裝DNW的USB驅動程式




4.按下DMA2440設備下的Reset鈕, 並在PC上按下空白鍵
5. 按1選擇功能[1],並開啟Win CE影像檔
6.下載完成後選擇8重新配置Win CE
7.選擇n
8.選擇4
9.選擇3再選y
10.燒錄完成後選7後再選0
11.設定3(Win CE)
12.選擇15再選y, 最後重新按下DMA2440的重置鈕, 就可以看到Win CE
