 * @brief Proximity 16 Click example
 *
 * # Description
 * This example demonstrates the use of Proximity 16 Click board by reading and displaying
 * 8x8 zones measurements on the USB UART.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Reads all zone measurements approximately every 500ms and logs them to the USB UART as an 8x8 map. 
 * The silicon temperature measurement in degrees Celsius is also displayed.
