 * @file main.c
 * @brief HW Monitor 2 Click example
 *
 * # Description
 * This example demonstrates the use of the HW Monitor 2 Click board™.
 * The demo application monitors analog voltage inputs and local temperature data.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of the I2C module, log UART and additional pins.
 * After the driver init, the app executes a default configuration.
 *
 * ## Application Task
 * This example displays the Analog Voltage Inputs from CH0 to CH6 [mV] 
 * and Temperature [degree Celsius] data.
 * Results are being sent to the UART Terminal, where you can track their changes.
