 * @brief DcMotor8 Click example
 * 
 * # Description
 * This click can drive simple DC motors with brushes, providing them with a significant amount 
 * of current and voltage up to 40V. The click has one control input, that uses the PWM signal 
 * from the host MCU. It uses the half-bridge topology to regulate the speed of the motor 
 * rotation, employs advanced dead-time circuitry that monitors the output stage, providing 
 * maximum switching efficiency and features an advanced technique to avoid shoot-through 
 * currents.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and enables the click board.
 * 
 * ## Application Task  
 * This is an example that demonstrates the use of DC Motor 8 click
 * board by increasing and decreasing the motor speed.
 * DC Motor 8 Click communicates with the register via the PWM interface.
 * Results are being sent to the Usart Terminal where you can track their changes.
