|
|
* Interface for touchscreen driver which includes touchscreen calibration,
|
|
* retrieving measurements etc.
|
|
*
|
|
* \par Usage
|
|
*
|
|
* -# Call TSD_Initialize() whenever the touchscreen should start the
|
|
* calibration process (as it is done in the function).
|
|
* -# Declare a global TSD_PenPressed function anywhere in your code. This
|
|
* function will get called every time the pen is pressed on the screen.
|
|
* -# Declare a global TSD_PenMoved function, which will get called whenever
|
|
* the pen stays in contact with the screen but changes position.
|
|
* -# Declare a global TSD_PenReleased function, which will be invoked as the
|
|
* pen is lifted from the screen.
