Actually I do not work on ucglib any more...

fornellas commented 4 years ago

Oh, sorry about that. So, does this mean the project is stale now? Maybe I can help carry it on if you want. I like ucglib a lot. I'm using it in a new project, for which I'd love to implement frame buffer to ucglib, but I'd feel less inclined to do it there's no chance for merging upstream.

olikraus commented 4 years ago

I would be happy if someone would continue here... However I am not sure how much I could contribute here. At least I could test the old behavior... And maybe I could also integrate the u8g2 font render engine... so that we can takeover all the latest fonts from u8g2.

fornellas commented 4 years ago

That would be great! You do have experience on the problem domain, even small comments on pull requests are good.

I'll do this PR for fixing warnings for starter.
