/* File Info: ------------------------------------------------------------------
User NOTES
1. How To use this driver:
--------------------------
- This driver is used to drive directly in video mode a LCD TFT using the DSI interface.
The following IPs are implied : DSI Host IP block working
in conjunction to the LTDC controller.
- This driver is linked by construction to LCD KoD mounted on board MB1166.
2. Driver description:
---------------------
+ Initialization steps:
o Initialize the LCD using the BSP_LCD_Init() 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 whole 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.
