 * @brief Brushless 24 Click example
 *
 * # Description
 * This application is a schowcase of controlling speed of brushless motor using Brushless 24 Click.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of LOG, PWM module and additional pins.
 *
 * ## Application Task
 * In a span of second changes duty cycle from 0 to 100% which is changing speed of the motor.
