Partial refresh

Open KenjiYANAGAWA opened this issue 5 years ago • 1 comments

Is there a way to partially refresh the screen instead of a full refresh?

I am asking this because I want to add lines smoothly as quickly as possible, but the refresh speed is too slow and I thought that is because it has to refresh the whole screen now.

Why has no one answer this question?

I'm not sure if this answers the question, but I was looking for a way to update the screen without having it flash to black. If this is what you're looking for, you need to use EPD_IT8951_1bp_Refresh with the A2_Mode. 4bpp will always flash to black, 1bpp will not.

You do have to do a full refresh now and again. The Wiki goes into this.
