This board doesn't has psram and this causing crash when lvgl buffer is 100%. If I think correctly with smaller buffer it should work. Anyone have any ideas how to solve this problem?

1 bit color depth is not supported. Use the most recent code.

clydebarrow commented 3 months ago

And just FYI, I have tested this on an Inkplate 6 Plus in monochrome mode (but using 16 bit color depth in LVGL) and it works ok. Slow, obviously, and you need to make all backgrounds pure black, but it does work. Better support for monochrome and e-ink will come in the future.
