 * \brief MUX 2 Click example
 * 
 * # Description
 * Sets the current active channel. Changes the channel every 5 sec.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes GPIO module and sets RST, CS, PWM and INT pins as OUTPUT.
 * 
 * ## Application Task  
 * Changes currently active channel every 5 sec.
