 * @brief ISO ADC 7 Click example
 *
 * # Description
 * This example demonstrates the use of ISO ADC 7 click board by reading and displaying
 * the voltage levels from 3 isolated analog input channels.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 * The full-scale voltage input range is set to +-1.2V for all channels.
 *
 * ## Application Task
 * Reads the voltage levels from all 3 isolated analog input channels and displays
 * the results on the USB UART once per second approximately.
