─ Hardware and Software SPI (any pin on AVR can be selected with SW SPI . SW SPI is slower than HW)
─ functions "ls020_put_string8" and "ls020_put_string8_vertical" supports 4 types of characters, transparent and with background (two types is with diacritics)
─ put string from PROG memory "ls020_put_string8_P". (horizontal and vertical for 4 types of characters)
─ put char and string. (horizontal and vertical)
─ Shapes like pixel8, pixel16, line, circle, rectangles ...

─ Horizontal and vertical slide bar (progressbar)
─ Show bitmap on LCD "s65_load_picture16" function
─ Pictures rotation (90 degree - vertical)
─ delay reduction (I thing the driver is faster)
─ Deactivate and Activate the screen
─ Inversion mode of LCD
─ Functions description
─ LCD backlight PWM control-brightness can be set
