This function initializes calibration information in a global parameter vCalcParam, which is used to convert non-calibrated points to calibrated points by the TouchPanelCalibrateAPointfunction.
VOID TouchPanelSetCalibration( INT32 cCalibrationPoints , INT32 * pScreenXBuffer , INT32 * pScreenYBuffer , INT32 * pUncalXBuffer , INT32 * pUncalYBuffer );
Parameters
- cCalibrationPoints
- Integer indicating the number of calibration points.
- pScreenXBuffer
- Specifies an array of screen x-coordinates displayed.
- pScreenYBuffer
- Specifies an array of screen y-coordinates displayed.
- pUncalXBuffer
- Specifies an array of x-coordinates collected.
- pUncalYBuffer
- Specifies an array of y-coordinates collected.
Remarks
This is the two-dimensional version of the transform. A simpler one-dimensional transform is in the MDD code. The preprocessor variable TWO_DIMENSIONAL_CALIBRATION can be used to select which transform to use.
The two-dimensional version is more complicated but more accurate because it does not assume independent x and y values.
Requirements
