EricLew 0:ad9dfc0179dc 42 1. How To use this driver:
EricLew 0:ad9dfc0179dc 43 --------------------------
EricLew 0:ad9dfc0179dc 44 - The LCD st7735 component driver MUST be included with this driver.
EricLew 0:ad9dfc0179dc 45
EricLew 0:ad9dfc0179dc 46 2. Driver description:
EricLew 0:ad9dfc0179dc 47 ---------------------
EricLew 0:ad9dfc0179dc 48 + Initialization steps:
EricLew 0:ad9dfc0179dc 49 o Initialize the LCD using the BSP_LCD_Init() function.
EricLew 0:ad9dfc0179dc 50
EricLew 0:ad9dfc0179dc 51 + Display on LCD
EricLew 0:ad9dfc0179dc 52 o Clear the whole LCD using the BSP_LCD_Clear() function or only one specified
EricLew 0:ad9dfc0179dc 53 string line using the BSP_LCD_ClearStringLine() function.
EricLew 0:ad9dfc0179dc 54 o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
EricLew 0:ad9dfc0179dc 55 function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
EricLew 0:ad9dfc0179dc 56 o Display a string line on the specified position (x,y in pixel) and align mode
EricLew 0:ad9dfc0179dc 57 using the BSP_LCD_DisplayStringAtLine() function.
EricLew 0:ad9dfc0179dc 58 o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, ..)
EricLew 0:ad9dfc0179dc 59 on LCD using a set of functions.
