Thanks for the followup! I was just in China visiting LED strip suppliers and they all said to switch to the SK9822 if possible as APA continues to have supply issues. Heard everything from that they have old fabs, oxidation issues, to disagreements with their Chinese side of the business (they’re based out of Taiwan).
I wonder if the ratios on the SK9822 for brightness adjustment are just a little bit different than APA102, and it can be adjusted with a tweak to the algorithm. I have some samples, but no time as of yet to try it out. I’ll report back if I get it to work.
