Description

I was hoping to do a PR to add an example of the featherwing display I have but I have bumped up against an issue with fading blacks. I have tried address the issue myself but I fear I am out of my depth now.

When using the default settings (with the added colstart=0) I see some fading/sparkling from the right (example below)

I tried using the custom lut from the magtag example, the blacks stay but the display becomes quite noisy.

Any help would be greatly appreciated.

Research direction

The payload names no files or tests. Start by reproducing the SSD1680 FeatherWing display behavior with the default settings and the MagTag custom LUT, then determine whether the fading or noise can be resolved and whether a working example can be added.
