Achieve precise RF signal management with MASWSS0115 and STM32F756ZG

/*!
 * @file main.c
 * @brief RF Switch Click Example.
 *
 * # Description
 * This is an example that demonstrates the use of the RF Switch Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enable's - GPIO, also write log and powers on device.
 *
 * ## Application Task
 * Waiting for valid user input and executes functions based on set of valid commands.
 * Results are being sent to the Usart Terminal where you can track their changes.
