 * \brief Brushless6 Click example
 * 
 * # Description
 * Brushless 6 Click is designed to drive a three-phase sensorless.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the logger and the Click board.
 * 
 * ## Application Task  
 * This function drives the motor in both directions increasing and decreasing the speed of the motor.
 * 
 * ## NOTE
 * The maximal PWM Clock frequency for this Click board is 500 Hz. 
 * So, the user will need to decrease the MCU's main clock frequency in MCU Settings in order to get up-to 500 Hz PWM clock frequency.
