 * @brief Fan 5 Click example
 *
 * # Description
 * This example demonstrates the use of FAN 5 click board by controlling and 
 * regulating the fan motors speed.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver, performs the click default configuration, reads 
 * manufacturer id and sets configuration in correspondence to user-selected mode.
 *
 * ## Application Task
 * If Fan control is selected example will monitor FAN 1 speed and if the speed 
 * falls below 500 RPM for longer then 2.4 seconds fan output will be disabled.
 * In other case, example is showcasing speed control by changing duty cycle and 
 * monitoring fan speed.
