bcostm	0:c9112f0c67e3	4	* @author MCD Application Team
bcostm	0:c9112f0c67e3	5	* @version V1.0.0
bcostm	0:c9112f0c67e3	6	* @date 25-June-2015
bcostm	0:c9112f0c67e3	7	* @brief This file includes the driver for Liquid Crystal Display (LCD) module
bcostm	0:c9112f0c67e3	8	* mounted on STM32746G-Discovery board.
bcostm	0:c9112f0c67e3	9	@verbatim
bcostm	0:c9112f0c67e3	10	1. How To use this driver:
bcostm	0:c9112f0c67e3	11	--------------------------
bcostm	0:c9112f0c67e3	12	- This driver is used to drive directly an LCD TFT using the LTDC controller.
bcostm	0:c9112f0c67e3	13	- This driver uses timing and setting for RK043FN48H LCD.
bcostm	0:c9112f0c67e3	14
bcostm	0:c9112f0c67e3	15	2. Driver description:
bcostm	0:c9112f0c67e3	16	---------------------
bcostm	0:c9112f0c67e3	17	+ Initialization steps:
bcostm	0:c9112f0c67e3	18	o Initialize the LCD using the BSP_LCD_Init() function.
bcostm	0:c9112f0c67e3	19	o Apply the Layer configuration using the BSP_LCD_LayerDefaultInit() function.
bcostm	0:c9112f0c67e3	20	o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
bcostm	0:c9112f0c67e3	21	o Enable the LCD display using the BSP_LCD_DisplayOn() function.
bcostm	0:c9112f0c67e3	22
bcostm	0:c9112f0c67e3	23	+ Options
bcostm	0:c9112f0c67e3	24	o Configure and enable the color keying functionality using the
bcostm	0:c9112f0c67e3	25	BSP_LCD_SetColorKeying() function.
bcostm	0:c9112f0c67e3	26	o Modify in the fly the transparency and/or the frame buffer address
bcostm	0:c9112f0c67e3	27	using the following functions:
bcostm	0:c9112f0c67e3	28	- BSP_LCD_SetTransparency()
bcostm	0:c9112f0c67e3	29	- BSP_LCD_SetLayerAddress()
bcostm	0:c9112f0c67e3	30
bcostm	0:c9112f0c67e3	31	+ Display on LCD
bcostm	0:c9112f0c67e3	32	o Clear the hole LCD using BSP_LCD_Clear() function or only one specified string
bcostm	0:c9112f0c67e3	33	line using the BSP_LCD_ClearStringLine() function.
bcostm	0:c9112f0c67e3	34	o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
bcostm	0:c9112f0c67e3	35	function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
bcostm	0:c9112f0c67e3	36	o Display a string line on the specified position (x,y in pixel) and align mode
bcostm	0:c9112f0c67e3	37	using the BSP_LCD_DisplayStringAtLine() function.
bcostm	0:c9112f0c67e3	38	o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
bcostm	0:c9112f0c67e3	39	on LCD using the available set of functions.
