/* File Info : -----------------------------------------------------------------
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 and ST7789H2 components 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.
