 * @brief Thermo 29 Click example
 *
 * # Description
 * This example demonstrates the use of Thermo 29 click board by reading and displaying
 * the temperature measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger, and performs the click default configuration which enables
 * continuous conversion and sets the conversion rate to 1 Hz with a data ready flag enabled on
 * the alert pin. After that, reads and displays the device 48-bit unique ID.
 *
 * ## Application Task
 * Waits for the data ready alert flag, then reads the temperature measurement in Celsius
 * and displays the results on the USB UART approximately once per second.
