bcostm 0:d83f1c8ca282 23 1. How To use this driver:
bcostm 0:d83f1c8ca282 24 --------------------------
bcostm 0:d83f1c8ca282 25 - This driver is used to drive indirectly an LCD TFT.
bcostm 0:d83f1c8ca282 26 - This driver supports the LS016B8UY LCD.
bcostm 0:d83f1c8ca282 27 - The LS016B8UY and ST7789H2 components driver MUST be included with this driver.
bcostm 0:d83f1c8ca282 28
bcostm 0:d83f1c8ca282 29 2. Driver description:
bcostm 0:d83f1c8ca282 30 ---------------------
bcostm 0:d83f1c8ca282 31 + Initialization steps:
bcostm 0:d83f1c8ca282 32 o Initialize the LCD using the BSP_LCD_Init() function.
bcostm 0:d83f1c8ca282 33
bcostm 0:d83f1c8ca282 34 + Display on LCD
bcostm 0:d83f1c8ca282 35 o Clear the hole LCD using BSP_LCD_Clear() function or only one specified string
bcostm 0:d83f1c8ca282 36 line using the BSP_LCD_ClearStringLine() function.
bcostm 0:d83f1c8ca282 37 o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
bcostm 0:d83f1c8ca282 38 function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
bcostm 0:d83f1c8ca282 39 o Display a string line on the specified position (x,y in pixel) and align mode
bcostm 0:d83f1c8ca282 40 using the BSP_LCD_DisplayStringAtLine() function.
bcostm 0:d83f1c8ca282 41 o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
bcostm 0:d83f1c8ca282 42 on LCD using the available set of functions.
