 * @file main.c
 * @brief HBridge6 Click example
 *
 * # Description
 * This is an example that demonstrates the use of H-Bridge 6 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enables - I2C,
 * reset the device and set default configuration,
 * initialization and configure the PWM, also write log.
 *
 * ## Application Task
 * It shows moving in the clockwise direction of rotation
 * and moving in the counterclockwise direction of rotation
 * from slow to fast speed.
 * All data logs write on USB uart changes.
