 * @brief IPS Display 2 Click example
 *
 * # Description
 * This example demonstrates the use of the IPS Display 2 Click board by showing
 * a practical example of using the implemented functions.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Showcases the text writing example as well as drawing pictures and objects,
 * and filling the whole screen with a desired color. All data is logged on the USB UART
 * where you can track the program flow.
