##### How to use this driver #####
==============================================================================
[..]
(#) This driver is used to drive indirectly an LCD TFT.
(#) This driver supports the LS016B8UY LCD.
(#) The LS016B8UY component driver MUST be included with this driver.
[..] Driver description:
(#) Initialization steps:
(++)Initialize the LCD using the BSP_LCD_Init() function.
(#) Display on LCD
(++) Clear the hole LCD using BSP_LCD_Clear() function or only one specified string
line using the BSP_LCD_ClearStringLine() function.
(++) 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
(++) Display a string line on the specified position (x,y in pixel) and align mode
using the BSP_LCD_DisplayStringAtLine() function.
(++) Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
on LCD using the available set of functions.
