Control different types of brushed motors with DRV8873 and PIC32MZ2048EFM100

/*!
 * @file main.c
 * @brief H-Bridge 14 Click example
 *
 * # Description
 * This example demonstrates the use of the H-Bridge 14 board by driving the 
 * motor in both directions with braking and coasting in between.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Drives the motor in both directions with coasting and braking in between, every sate is lasting 5 seconds.
