Async interface for update() in micropython

[nmattia]

Hi,

I love using picographics (with micropython), and I was wondering if it'd be possible to have an asynchronous interface for update()?

From a quick look at the source it seems to be hot looping until the display has finished refreshing. I'm using this with the Inky Frame 7.3", where the update takes ~40s, which unfortunately makes using a watchdog impossible (the max timeout value is ~8s).

Thanks!

In the current beta release you should be able to graphics.set_blocking(False) and sit in a while graphics.is_busy(): loop in an async function.

Using core1 to extend the watchdog timeout is also a potential option: https://gist.github.com/Gadgetoid/81cbeba0b60c0901209fbd0e543032ef
