bcostm	0:0002c86c2220	40	User NOTES
bcostm	0:0002c86c2220	41	1. How To use this driver:
bcostm	0:0002c86c2220	42	--------------------------
bcostm	0:0002c86c2220	43	- This driver is used to drive directly in video mode a LCD TFT using the DSI interface.
bcostm	0:0002c86c2220	44	The following IPs are implied : DSI Host IP block working
bcostm	0:0002c86c2220	45	in conjunction to the LTDC controller.
bcostm	0:0002c86c2220	46	- This driver is linked by construction to LCD KoD mounted on board MB1166.
bcostm	0:0002c86c2220	47
bcostm	0:0002c86c2220	48	2. Driver description:
bcostm	0:0002c86c2220	49	---------------------
bcostm	0:0002c86c2220	50	+ Initialization steps:
bcostm	0:0002c86c2220	51	o Initialize the LCD using the BSP_LCD_Init() function.
bcostm	0:0002c86c2220	52	o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
bcostm	0:0002c86c2220	53	o Enable the LCD display using the BSP_LCD_DisplayOn() function.
bcostm	0:0002c86c2220	54
bcostm	0:0002c86c2220	55	+ Options
bcostm	0:0002c86c2220	56	o Configure and enable the color keying functionality using the
bcostm	0:0002c86c2220	57	BSP_LCD_SetColorKeying() function.
bcostm	0:0002c86c2220	58	o Modify in the fly the transparency and/or the frame buffer address
bcostm	0:0002c86c2220	59	using the following functions:
bcostm	0:0002c86c2220	60	- BSP_LCD_SetTransparency()
bcostm	0:0002c86c2220	61	- BSP_LCD_SetLayerAddress()
bcostm	0:0002c86c2220	62
bcostm	0:0002c86c2220	63	+ Display on LCD
bcostm	0:0002c86c2220	64	o Clear the whole LCD using BSP_LCD_Clear() function or only one specified string
bcostm	0:0002c86c2220	65	line using the BSP_LCD_ClearStringLine() function.
bcostm	0:0002c86c2220	66	o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
bcostm	0:0002c86c2220	67	function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
bcostm	0:0002c86c2220	68	o Display a string line on the specified position (x,y in pixel) and align mode
bcostm	0:0002c86c2220	69	using the BSP_LCD_DisplayStringAtLine() function.
bcostm	0:0002c86c2220	70	o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
bcostm	0:0002c86c2220	71	on LCD using the available set of functions.
