 * \brief Brushless3 Click example
 * 
 * # Description
 * This Click has three-phase sensorless motor driver and 
 * with an external power supply it drives a brushless DC motor.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - I2C, set default parameter value.
 * 
 * ## Application Task  
 * This is an example which demonstrates the use of Brushless 3 Click board.
 * Read and display float motor frequency value from the DRV10983 sensorless 
 * BLDC motor driver on Brushless 3 Click board. Results are being sent to 
 * the Usart Terminal where you can track their changes.
