searching for the example code of smooth arcs picture

[Feliniuss]

Hey everyone,
I came across the picture on the main page of the TFT_eSPI GitHub repository showcasing smooth arc anti-aliased meter gauges on a 320x240 TFT.

Is there any example code available for this, or has anyone already implemented something similar that runs smoothly?

I'm using a 480x320 display, but a 320x240 implementation would also be fine—I’m mainly interested in understanding how it's programmed.

My own version is a bit laggy and keeps refreshing the screen entirely. Ideally, I want to create a digital meter that updates only the values every 20ms, without redrawing the full display.

Thanks a lot! ❤️
