| * \addtogroup tsd_module TouchScreen Driver | |
| * | |
| * \section Purpose | |
| * | |
| * This unit provides a very powerful touchscreen driver which handles all the | |
| * complexity. This includes touchscreen calibration, retrieving measurements, | |
| * configuring the TSADC, etc. | |
| * | |
| * \section Usage | |
| * | |
| * -# Implement ADC interrupt handler in application, to invoke TSD_Handler() | |
| * to handle ADC sampling events for touchscreen monitor. | |
| * -# Call TSD_Initialize() to initialize ADC used for touchscreen. | |
| * -# Call TSD_Calibrate() to do touchscreen calibration with LCD, and enable | |
| * touchscreen monitor if calibration success. | |
| * -# Call TSD_Enable() to enable or disable touchscreen monitoring. | |
| * -# 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. | |
