 * @brief DcMotor3 Click example
 * 
 * # Description
 * This click has four operating modes: clockwise, counter-clockwise, short brake and stop. 
 * The operating mode is configured through IN1 and IN2 pins.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - GPIO,
 * PWM initialization, set PWM duty cycle and PWM frequency, start PWM, enable the engine, and start write log.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of DC Motor 3 Click board.
 * DC Motor 3 Click communicates with register via PWM interface.
 * It shows moving in the left direction from slow to fast speed
 * and from fast to slow speed.
 * Results are being sent to the Usart Terminal where you can track their changes.
