 * \brief Brushless7 Click example
 * 
 * # Description
 * This example demonstrates the use of Brushless 7 Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Sets the default configuration and then configures the Click board for the selected mode.
 * 
 * ## Application Task  
 * Increases and decreases the speed of the motor rotation by setting the duty cycle or 
 * rpm values depending on which mode is previously selected. 
 * It also switches the direction of rotation at the beginning of each cycle. 
 * All data is being logged on the USB UART where you can track their changes.
