 * @brief Grid-EYE 2 Click example
 *
 * # Description
 * This example demonstrates the use of Grid-EYE 2 click by reading and displaying
 * the temperature measurements as an 8x8 pixels grid.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration which enables
 * the data ready interrupt and sets data measurement to 10 frames per second.
 *
 * ## Application Task
 * Waits for a data ready interrupt and then reads the grid temperature measurements
 * and displays the results on the USB UART in a form of an 8x8 pixels grid.
