phungductung	0:4e245f4bc8ac	4	* @author MCD Application Team
phungductung	0:4e245f4bc8ac	5	* @version V1.0.0
phungductung	0:4e245f4bc8ac	6	* @date 25-June-2015
phungductung	0:4e245f4bc8ac	7	* @brief This file includes the driver for Liquid Crystal Display (LCD) module
phungductung	0:4e245f4bc8ac	8	* mounted on STM32746G-Discovery board.
phungductung	0:4e245f4bc8ac	9	@verbatim
phungductung	0:4e245f4bc8ac	10	1. How To use this driver:
phungductung	0:4e245f4bc8ac	11	--------------------------
phungductung	0:4e245f4bc8ac	12	- This driver is used to drive directly an LCD TFT using the LTDC controller.
phungductung	0:4e245f4bc8ac	13	- This driver uses timing and setting for RK043FN48H LCD.
phungductung	0:4e245f4bc8ac	14
phungductung	0:4e245f4bc8ac	15	2. Driver description:
phungductung	0:4e245f4bc8ac	16	---------------------
phungductung	0:4e245f4bc8ac	17	+ Initialization steps:
phungductung	0:4e245f4bc8ac	18	o Initialize the LCD using the BSP_LCD_Init() function.
phungductung	0:4e245f4bc8ac	19	o Apply the Layer configuration using the BSP_LCD_LayerDefaultInit() function.
phungductung	0:4e245f4bc8ac	20	o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
phungductung	0:4e245f4bc8ac	21	o Enable the LCD display using the BSP_LCD_DisplayOn() function.
phungductung	0:4e245f4bc8ac	22
phungductung	0:4e245f4bc8ac	23	+ Options
phungductung	0:4e245f4bc8ac	24	o Configure and enable the color keying functionality using the
phungductung	0:4e245f4bc8ac	25	BSP_LCD_SetColorKeying() function.
phungductung	0:4e245f4bc8ac	26	o Modify in the fly the transparency and/or the frame buffer address
phungductung	0:4e245f4bc8ac	27	using the following functions:
phungductung	0:4e245f4bc8ac	28	- BSP_LCD_SetTransparency()
phungductung	0:4e245f4bc8ac	29	- BSP_LCD_SetLayerAddress()
phungductung	0:4e245f4bc8ac	30
phungductung	0:4e245f4bc8ac	31	+ Display on LCD
phungductung	0:4e245f4bc8ac	32	o Clear the hole LCD using BSP_LCD_Clear() function or only one specified string
phungductung	0:4e245f4bc8ac	33	line using the BSP_LCD_ClearStringLine() function.
phungductung	0:4e245f4bc8ac	34	o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
phungductung	0:4e245f4bc8ac	35	function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
phungductung	0:4e245f4bc8ac	36	o Display a string line on the specified position (x,y in pixel) and align mode
phungductung	0:4e245f4bc8ac	37	using the BSP_LCD_DisplayStringAtLine() function.
phungductung	0:4e245f4bc8ac	38	o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
phungductung	0:4e245f4bc8ac	39	on LCD using the available set of functions.
