 * @brief AD-SWIO 3 Click example
 *
 * # Description
 * This library contains API for the AD-SWIO 3 Click driver 
 * for measurements of the analog output, analog input, digital input, 
 * resistance temperature detector (RTD), and thermocouple measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of SPI and log UART.
 * After driver initialization, the app executes a default configuration 
 * that enables and sets it to measure IOP/ION voltage input from 0V to 12V, 
 * with 4.8k SPS and enabled four diagnostics measurements (AVDD, VASS, VACC and LVIN).
 *
 * ## Application Task
 * This example demonstrates the use of the AD-SWIO 3 Click board. 
 * The demo application reads and displays the voltage level input, 
 * measured by the voltage between the I/OP and I/ON screw terminals 
 * and NTC thermistor temperature in degrees Celsius.
 * Results are being sent to the UART Terminal, where you can track their changes.
