 * @brief ECG 5 Click Example.
 *
 * # Description
 * This is an example which demonstrates the use of ECG 5 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes ADC and GPIO.
 *
 * ## Application Task
 * Reads ADC value and sends results on serial plotter every 5 ms.
