Image Crossfade

spinal · January 7, 2017, 5:02pm

In a slight continuation from the screen brightness thread, I have started an example of fading between two images. It flickers a bit, but then, everything that attempts to fade does right now.

If anyone thinks that they can clean it up a little, maybe cut down the flicker a bit, please show what you can do

Here is the code, it’s quite simple.

Do twitter videos work here?

Been messing with the timing on my #arduboy crossfade test. It looks much better in real life. pic.twitter.com/3CuxNHwPqu

WOW!

That looks a lot sexier than I thought it would!

Regarding the sync issues, are there any commands for the oled that will force reset the redraw? Perhaps we can just send a command or two every couple of frames to force a resync even if we don’t know when the vblank is?
