Seize control and dominate the motion of your BLDC with STSPIN233 and MKV58F1M0VLQ24

/*!
 * \file 
 * \brief Stspin233 Click example
 * 
 * # Description
 * This application is motor driver.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver and configures the Click board.
 * 
 * ## Application Task  
 * This example demonstrates the use of STSPIN233 Click board, by running the motor clockwise and counter clockwise.
 * All results will be displayed on USB UART.
 * 
 * *note:* 
 * For all other commands that you can use to control your engine, 
 * see the firmware documentation. We used an 8 pole motor for the test.
