-/* File Info : -----------------------------------------------------------------
- User NOTES
-1. How To use this driver:
---------------------------
- - The LCD st7735 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 whole LCD using the 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, ..)
- on LCD using a set of functions.
