 * @file main.c
 * @brief TFmini Click Example.
 *
 * # Description
 * This example demonstrates the use of TFmini click board by reading the measurements
 * from the attached TFmini-S or TFmini Plus sensors.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and the click board, and reads the firmware version of the attached sensor.
 *
 * ## Application Task
 * Reads the target distance, signal strength and the internal sensor temperature every 100ms approximately,
 * and displays the results on the USB UART.
