 * \brief Opto Encoder 3 Click example
 * 
 * # Description
 * The demo application displays the counter value or displays the status of each O pins.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configures the driver and logger, and selects the demo application mode.
 * 
 * ## Application Task  
 * Depending on the demo application mode set in the application init it:
 *    - Measures and displays the value of the counter - DEMO_CNT mode; or
 *    - Draws the status of each O pin - DEMO_GRAPH mode.
