How to display a compass needle?

[tve]

I'd like to display a compass needle "full screen" on an attached display (well, it's going to be round, so it won't use the full display in the long direction). The compass would be animated to point north as one rotates the unit using a digital compass. I'd like the needle to rotate smoothly, not in something like 10 degree increments. How would I implement this best? I'm not seeing anything that is not a rectangle or a mask/image and it seems to me that I either need arbitrary lines to draw the needle or rotate a mask/image by an arbitrary angle. Maybe I'm missing something or am not thinking about the obvious?

I think you're looking for something like Outlines.

The piu/outline/clock example has a continuous sweep hand for seconds.

The blog post has a high level introduction including an example of using Figma to create the outlines.

The Node-RED MCU Edition dashboard implementation includes gauges, one of which is a kind of compass.
