PB自带的触摸屏校准代码D:\WINCE420\PUBLIC\COMMON\OAK\DRIVERS\TOUCH

!18M!8Xea 可以参考PLATFORM BUILDER的帮助文档:

Windows CE Features > Shell and User Interface > User Interface > Touch Screen (Stylus) ------CE5.0

z 9k3@\7         Platform Development > Developing Platform Elements > Customizing the User Interface > Touch Screen Calibration Reference -------CE4.2

Touch Panel校准过程如下：

1）调用TouchPanelEnable启动触摸屏

2）调用TouchPanelGetDeviceCaps，通过设置参数TPDC_CALIBRATION_POINT_COUNT_ID来获得校准用触点的个数

3）取校准点，对每个校准点都有以下过程

   A：调用TouchPanelGetDeviceCaps，设置参数TPDC_CALIBRATION_POINT_ID来获得校准点坐标

   B：在上述校准点坐标处画十字，并等待用户点击

   C：调用TochPanelReadCalibrationPoint来获得上述校准点坐标处触摸屏对应的数据

4）当取完校准用的所有的点，调用TouchPanelSetCalibration来计算校准系数，该函数实现没有找到

程序流程：

TouchPanelGetDeviceCaps-->

DdsiTouchPanelGetDeviceCaps(参数为TPDC_CALIBRATION_POINT_ID)-->

TouchDriverCalibrationPointGet(得到校准点之一的坐标，该坐标为screen坐标）

英文资料如下：

The following steps detail the basic algorithm that you, the driver developer, can use to sample and calibrate the screen with the touch screen driver:

1. Call the TouchPanelEnable function to start the screen sampling.
2. Call the TouchPanelGetDeviceCaps function to request the number of sampling points.
3. For every calibration point, perform the following steps:
   1. Call TouchPanelGetDeviceCaps to get a calibration coordinate.
   2. Draw a crosshair at the returned coordinate.
   3. Call the TouchPanelReadCalibrationPoint function to get calibration data.
4. Call the TouchPanelSetCalibration function to calculate the calibration coefficients.

HINSTANCE hinstance = LoadLibrary(_T("coredll.dll")); 
if (hinstance == NULL) 
{ 
     AfxMessageBox (L"instance == NULL"); 
      return; 
} 
_TouchCalibrate TouchCalibrate = NULL; 
TouchCalibrate = (_TouchCalibrate)GetProcAddress(hinstance , L"TouchCalibrate"); 
if (TouchCalibrate == NULL) 
{ 
      AfxMessageBox (L"TouchCalibrate == NULL"); 
      return; 
} 
TouchCalibrate (); 
FreeLibrary(hinstance ); 

      要自已写一个触摸屏的校准应用程序该怎么写?
      有没有那位大哥做过?给点提示了!急啊!
      我用微软private下面的一个TOUCHTEST的里面的测试代码试,校准完了触摸屏就没反应了?
      我的程序顺序是这样:LoadDrvier-->TouchPanelEnable-->TouchPanelGetDeviceCaps-->TouchPanelReadCalibrationPoint
--->TouchPanelSetCalibration-->FreeDriver.
      校准完了后系统的触摸屏就没反应了! ]-Z=" Y PY T+_ pm DDN [NE : $ @ ~bSPtH ]6d 1m*fk M#
