RGBW Dithering docs warn about FPS. But which FPS metric should I be looking at?

[nefariouslegion]

Hi,

Bit of a beginner question here. I have the SK6812 RGBW strip being controlled by my adafruit feather RP2040 scorpio with HyperSerialPico. Now I was going to configure the "RGBW with dithering by Infinite Color Engine" and it's corresponding settings. But reading the docs there's a warning about a minimum FPS of 50 with the recommended being 60-80. But I'm unsure which FPS metric that's referring to?

In my logs I see lines like this that show a few different FPS counters:
[PERFORMANCE] [USB: FPS = 30.02, decoding = 1ms, frames = 1802, invalid = 0, mode = direct], [LED0: FPS = 76.92, send = 4616, processed = 4616, dropped = 0], [INSTANCE0: FPS = 30.02, processed = 1802]

My guess is it's the LED0 FPS I should be looking at in which case I'm good. But wanted to double check.
Thanks!

Hi,

you are correct: the key is the infinite color engine, which produces many more intermediate frames than the grabber itself. And 76 FPS is fine, but this only tells you that such a number of frames per second were sent - not rendered. You must search for the HyperSerialPico response (with its own last statistics) in the logs when you disable the LED source in the remote tab.

Thanks for the reply!

When looking at my logs while disabling the LEDs in the Remote Control tab I get this output:

But I’m unsure whether this is good or bad lol

It's fine :-)
