Android 2.3有支援的新功能:Mobile Services for Near Field Communication

Draw 9-patch執行時出現錯誤.....

在android下，如果在做Widget做Nine-Patch Images(可伸展圖像)時，執行Draw 9-patch (draw9patch.bat)出現如下圖所示的錯誤出現，這是因為SDK 2.3版中少了一個檔案。

Windows CE: 控制直流馬達應用程式

接續前一篇文章，我們利用下列幾個函式來控制馬達
1. 開啟驅動程式
m_hdcmotor = CreateFile(_T("DCM1:"), GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, 0);
2. 啟動馬達
DeviceIoControl(m_hdcmotor, DC_SPEED_START, NULL, NULL, NULL, NULL, NULL, NULL);
3. 停止馬達
DeviceIoControl(m_hdcmotor, DC_SPEED_STOP, NULL, NULL, NULL, NULL, NULL, NULL);
4. 速度控制
DeviceIoControl(m_hdcmotor, DC_SPEED_INCREASE, &m_currdcmotor, NULL, NULL, NULL, NULL, NULL);

以上為馬達控制程式列表

Windows CE: 增加按鈕來啟動計時器或關閉計時器

接續2010年12月1日星期三的文章，其步驟如下：
1. 再增加兩張圖分別設定其ID值為IDB_START和IDB_STOP。
2. 宣告三個變數值
HANDLE hStart; //儲存開始位元圖的代碼
HANDLE hStop; //儲存停止位元圖的代碼
int run=1; //記錄運轉或停止
3. 在WM_CREATE訊息下，載入位元圖
hStart = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_START));
hStop = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_STOP));
4. 增加WM_LBUTTONDOWN訊息處理程式
case WM_LBUTTONDOWN:
int x,y;
x=LOWORD(lParam);
y=HIWORD(lParam);
if(x>=150 && x<=204 && y>=10 && y<=64)
run = 1-run;
if(run)
SetTimer(hWnd, 1, 200, NULL);
else
KillTimer(hWnd, 1);
InvalidateRect(hWnd, NULL, FALSE);
break;

5.在WM_PAINT訊息下，顯示開始或停止的圖片
if(run)
{
SelectObject(hdcMem, (HGDIOBJ) hStop);
GetObject(hStop, sizeof(BITMAP), &bmp);
}
else
{
SelectObject(hdcMem, (HGDIOBJ) hStart);
GetObject(hStart, sizeof(BITMAP), &bmp);
}

BitBlt(hdc, 150,10, bmp.bmWidth, bmp.bmHeight, hdcMem, 0,0, SRCCOPY);

Google公布了Android 2.3 Platform

http://developer.android.com/sdk/index.html

Windows CE: 利用計時器畫出馬達旋轉的圖

1. 建立dcMotor專案(Smart Device, Win 32)
2. 在資源檔中畫六張圖可呈現動畫, 您也可以將下列圖片下載, 放到dcMotor專案的res目錄下, 然後利用Import功能將圖片滙入。






3. 利用dcStatus來記綠馬達狀態, hBitmap可用來儲存六張圖片的資源代碼
int dcStatus = 0; //0-5
HANDLE hBitmap[6];

使用eclipse撰寫第一支Java程式的步驟

1.選擇File->New->Java Project
2. 為專案命名，按下Finish鍵。
3.在src目錄下按下右鍵，選擇New->Class
4. 為class命名，並選擇產生main函式再按Finish鍵
5.增加程式System.out.print
6.按下執行鈕
7.選擇OK鈕
8. 察看結果

WinCE 位元圖切換

完成的功能如下面這兩張圖。


其步驟如下：
1. 請利用Visual C++的Win 32 Smart Device專案。

2. 新增兩個位元圖。

下載USB HID測試程式及測試USB設備上的LED

在USB Central網站上提供許多USB學習資源

點選HID選項

將下載到的generic_hid_vb_46.zip解開

開啟Visual Studio 2005，選擇File選單中的Open之Project/Solution選項，開啟GenericHid。



然後利用USB線將USB發展工具與電腦連接在一起，再打開Cypress USB Control Panel，下載led.hex到發展工具。

按下Visual Studio的執行鈕後，設定Vendor ID及Product ID為1234及5678。

然後按下Find My Device按鈕及One按鈕，就可以觀察USB設備上LED的變化。

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
