 * @file main.c
 * @brief ISM RX 2 Click Example.
 *
 * # Description
 * This application shows capability of ISM RX 2 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialize GPIO pins and LOG module and sets default configuration.
 *
 * ## Application Task
 * Wait for the data pin to go down and start sampling and wait for sync word if it's received 
 * collect data to buffer till it receives 0 byte
 *
 * @note
 * Application task is broken down into two parts:
 * DEFAULT_EXAMPLE - Collects data from the OOK TX Click board and displays it on the 
 * USB UART terminal.
 * MANCHESTER_EXAMPLE - Collects Manchester encoded data from the ISM TX Click board, 
 * decodes it and displays it on the USB UART terminal.
