 * @brief Brushless14 Click example
 *
 * # Description
 * This application example showcases ability of the device to control motor,
 * It's speed and rotation direction. Also it gives user ability to change other
 * configuration parameters.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of communication modules (I2C, PWM, UART) and additional 
 * pins (INT, DIR). It reads ID from DAC ic to confirm communcation. Then
 * configures device for control.
 *
 * ## Application Task
 * Drives motor using PWM from 10% duty cycle to 100% and back to 0%. 
 * Increment is done by 10% in span of 2 seconds. Whenever application gets
 * to 0% duty cycle it chages direction of rotation.
