 * \brief c4dotmatrixr Click example
 * 
 * # Description
 * This example demonstrates the use of 4Dot-Matrix R Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and performs the Click default configuration.
 * 
 * ## Application Task  
 * Displays a desired text message and then numbers from -20 to 20 on the Click board.
 * Each step will be logged on the USB UART where you can track the program flow.
