+                                   User NOTES
+1. 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.
+
+2. Driver description:
+---------------------
+  + Initialization steps:
+     o Initialize the LCD using the BSP_LCD_Init() function.
+  
+  + Display on LCD
+     o Clear the hole 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.
