| * 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. | |
