Just bought the 4.2” waveshare e-paper display ( red/black. 400x300).
Only just got it , but to use I need ( so it appears) a character array to store data for part of the screen, which is used for refreshing ( haven’t gone through all that yet)
Was wondering if I could put this array into flash memory , so I could free off some SRAM? I’ve no idea if or how that is done .
Can I also offload the libraries in the some way ?
Using : epd4in2b, imagedata, epdpaint libraries for the display.
I’m planning on using a 1284, but just playing on a UNO atm . ( I’m using the 1284 for extra memory and as it’s available as a DIP, which fits my PCB capabilities)
