+  * @author  MCD Application Team
+  * @version V1.0.0
+  * @date    25-June-2015
+  * @brief   This file includes the driver for Liquid Crystal Display (LCD) module
+  *          mounted on STM32746G-Discovery board.
+  @verbatim
+  1. How To use this driver:
+  --------------------------
+     - This driver is used to drive directly an LCD TFT using the LTDC controller.
+     - This driver uses timing and setting for RK043FN48H LCD.
+  
+  2. Driver description:
+  ---------------------
+    + Initialization steps:
+       o Initialize the LCD using the BSP_LCD_Init() function.
+       o Apply the Layer configuration using the BSP_LCD_LayerDefaultInit() function.    
+       o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
+       o Enable the LCD display using the BSP_LCD_DisplayOn() function.
+  
+    + Options
+       o Configure and enable the color keying functionality using the 
+         BSP_LCD_SetColorKeying() function.
+       o Modify in the fly the transparency and/or the frame buffer address
+         using the following functions:
+         - BSP_LCD_SetTransparency()
+         - BSP_LCD_SetLayerAddress() 
+    
+    + Display on LCD
+       o Clear the hole LCD using BSP_LCD_Clear() function or only one specified string
+         line using the BSP_LCD_ClearStringLine() function.
+       o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
+         function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
+       o Display a string line on the specified position (x,y in pixel) and align mode
+         using the BSP_LCD_DisplayStringAtLine() function.          
+       o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap) 
+         on LCD using the available set of functions.
