 * @file 
 * @brief HBridge3 Click example
 * 
 * # Description
 * H-bridge in general, allows the current to flow in one or another direction.
 * This click is used for driving a H-Bridge motor by changing output states. 
 * The outputs can be pulse width modulated at frequencies up to 20kHz by means of PWM/DIR control. 
 * 
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes SPI and LOG modules, AN, RST, CS and PWM pins
 * 
 * ## Application Task  
 * This example demonstrates the use of H-Bridge 3 Click board, 
 * by running dc motor in both directions - increasing and decreasing PWM duty cycle.
 * Results are being sent to the Usart Terminal where you can track their changes.
