works fine, but i would like to have function more to scroll the display content up an down or move a bitmap on the screen.
would that be possible in fb mode?
Yes, possible. Question is detailed behaviour.
What would you do if the bitmap crosses the end of the screen?
- fall off the edge
- how about the "incoming pixels" if you move the whole screen? white/black? replicate the pixels that where there?
I wrote the function to invert the diplay.
Is it possilbe not to invert the whole screen? i would like to have the possibility to toggle invert mode before i print on the screen, so that only the new written area is inverted.
Yes, especially in FB mode you could invert an area. (if I recall the code correctly
Have no time to dive into the code for a definitive answer, but yes think so.
Drawback might be that code becomes complexer/slower.
has someone a recommendation of a menu library for this library?
no idea sorry.
