Author:
MCD Application Team
Version:
V2.0.0

30-December-2016
  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.
