Hello.
I'm building an educational device, which has a lot of text to display.
Using ST7920 with own "library" to have 8 lines of 16 characters on 128x64 pixels screen.
The issue is, that arraywrite/read takes too much memory. For example, the code below takes about 400 bytes of memory.

Code:
if dta>olddta then arraywrite topline, ["trendi:","a]mavali          "]
if dta<olddta then arraywrite topline, ["trendi:da]mavali           "]
if dta=olddta then arraywrite topline, ["trendi:stabiluri           "]
olddta=dta
Is there any other way for storing large text lines like this? (other than using internal/external EEPROM) ?
