 * \brief LcdMono Click example
 * 
 * # Description
 * This application sets text on lcd displey.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Driver initialization - Starting LCD Mono display. Print text to the display by changing font size ...
 * 
 * ## Application Task  
 * Drawing an image to the display every 3 second.
 * 
 * *note:* 
 * - Create Image:
 *     Save the image in resolution of 128x128 px with the extension (monochrome bmp) ...
 *     Upload the image to Image2Lcd program
 *     Set parameters to:
 *            1. Output file type : C array
 *            2. Scan Mode : Horisontal scan
 *            3. Bits Pixel : monochrome
 *            4. Max width and height : 128x128
 *            5. Check only MSB first
 *            6. Check Reverse color and adjust Normal type
 * The image to be generated should contain about 2048 bytes ...
 * Insert the image into the file Click_LCD_Mono_image.h
 *
 * - Create Font:
 *     Close existing project, open a new VTFT project
 *     Add label and adjust text font
 *     Generate source code
 *     Copy the font from resource.c file to this project in file Click_LCD_Mono_font.h
