TuxLeon	0:99b5a7505a7a	4	* @author MCD Application Team
TuxLeon	0:99b5a7505a7a	5	* @version V1.0.0
TuxLeon	0:99b5a7505a7a	6	* @date 25-June-2015
TuxLeon	0:99b5a7505a7a	7	* @brief This file includes the driver for Liquid Crystal Display (LCD) module
TuxLeon	0:99b5a7505a7a	8	* mounted on STM32746G-Discovery board.
TuxLeon	0:99b5a7505a7a	9	@verbatim
TuxLeon	0:99b5a7505a7a	10	1. How To use this driver:
TuxLeon	0:99b5a7505a7a	11	--------------------------
TuxLeon	0:99b5a7505a7a	12	- This driver is used to drive directly an LCD TFT using the LTDC controller.
TuxLeon	0:99b5a7505a7a	13	- This driver uses timing and setting for RK043FN48H LCD.
TuxLeon	0:99b5a7505a7a	14
TuxLeon	0:99b5a7505a7a	15	2. Driver description:
TuxLeon	0:99b5a7505a7a	16	---------------------
TuxLeon	0:99b5a7505a7a	17	+ Initialization steps:
TuxLeon	0:99b5a7505a7a	18	o Initialize the LCD using the BSP_LCD_Init() function.
TuxLeon	0:99b5a7505a7a	19	o Apply the Layer configuration using the BSP_LCD_LayerDefaultInit() function.
TuxLeon	0:99b5a7505a7a	20	o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
TuxLeon	0:99b5a7505a7a	21	o Enable the LCD display using the BSP_LCD_DisplayOn() function.
TuxLeon	0:99b5a7505a7a	22
TuxLeon	0:99b5a7505a7a	23	+ Options
TuxLeon	0:99b5a7505a7a	24	o Configure and enable the color keying functionality using the
TuxLeon	0:99b5a7505a7a	25	BSP_LCD_SetColorKeying() function.
TuxLeon	0:99b5a7505a7a	26	o Modify in the fly the transparency and/or the frame buffer address
TuxLeon	0:99b5a7505a7a	27	using the following functions:
TuxLeon	0:99b5a7505a7a	28	- BSP_LCD_SetTransparency()
TuxLeon	0:99b5a7505a7a	29	- BSP_LCD_SetLayerAddress()
TuxLeon	0:99b5a7505a7a	30
TuxLeon	0:99b5a7505a7a	31	+ Display on LCD
TuxLeon	0:99b5a7505a7a	32	o Clear the hole LCD using BSP_LCD_Clear() function or only one specified string
TuxLeon	0:99b5a7505a7a	33	line using the BSP_LCD_ClearStringLine() function.
TuxLeon	0:99b5a7505a7a	34	o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
TuxLeon	0:99b5a7505a7a	35	function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
TuxLeon	0:99b5a7505a7a	36	o Display a string line on the specified position (x,y in pixel) and align mode
TuxLeon	0:99b5a7505a7a	37	using the BSP_LCD_DisplayStringAtLine() function.
TuxLeon	0:99b5a7505a7a	38	o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
TuxLeon	0:99b5a7505a7a	39	on LCD using the available set of functions.
