switch graphics layer? #28

Open Neywiny opened 5 years ago

Neywiny commented 5 years ago

I want to do some real time drawing of values but the fill_triangle function, even with all points as variables so it's a straight look-up, is causing some flicker (I am not doing a screen fill every frame, just overwriting the stuff I need to). I know there's a way to do layer switching if I do 4-bit mode (I have the 5" touchscreen, and 800x400 can't fit into the chip's ram so I'm told). There's very few people trying to do this it seems, but I was just wondering if there's any library support for it?

EDIT: I mitigated most of the flicker by refining exactly what I needed to overwrite, but I would still appreciate support for layering

There isn't currently any library support, but this might be a nice feature to add. I'm going to leave this open for now so you can keep track.

Thank you. I'll keep trying on my end and if it works I'll try requesting it as an official addition.

Awesome. Sounds good.
