 * 
 * # Description
 * This application is used for powering 16x32 RGB LED matrices.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver, reset device and initializes
 * firmware depend on pattern used alongside with fonts
 * 
 * ## Application Task  
 * Test of panel brightnes, draws red cross on
 * the panel using pixel write function, writes text on panel using
 * write text function and finaly displays image on the panel.
