 * @file main.c
 * @brief ECG 7 Click Example.
 *
 * # Description
 * This example demonstrates the use of ECG 7 Click board by reading and displaying
 * the voltage from VOUT BUFF which can be visualized on the SerialPlot application.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads the output voltage and displays it on the USB UART (SerialPlot)
 * every 4ms approximately.
 *
 * @note
 * We recommend using the SerialPlot tool for data visualizing. 
 * Please make sure to set up ECG electrodes properly.
