Create whisper-quiet operation of your DC motor with TB9051FTG and STM32F410RB

/*!
 * @file main.c
 * @brief DCMotor18 Click example
 *
 * # Description
 * This example application showcases ability of click 
 * board to control DC motors using PWM modulation in 
 * both directions and different speeds.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of MCU communication modules (PWM, ADC, UART) 
 * and additioal gpio for control of the device. Then sets 
 * default configuration that enables device to control the DC motor.
 *
 * ## Application Task
 * Drives motor in one direction from 0 to 100% of the speed using 
 * PWM, and then returns it back to 0. Then changes the rotation
 * direction and repeats the process of increasing and decreasing 
 * acceleration.
