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 );
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.
