Experience the magic of precise motor control with DRV8143 and ATmega328P

 * @file main.c
 * @brief DC Motor 27 Click example
 *
 * # Description
 * This example demonstrates the use of the DC Motor 27 Click board by driving 
 * the motor at different speeds, enabling brake and coast modes.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Controls the motor speed by changing the PWM duty cycle every second, 
 * places the motor into coast or braking mode.
