Hi
has anyone tried to build a pov display using WLED? Is it even possible…updaterate?
I am trying to build pixel poi running on WLED. I have already some prototypes. So far they work really well but I want to integrate some pov effects.
Any help or info highly appreciated.

I was able to speed everything up by quite a bit… if I am not mistaken I get about 250 - 400FPS.
But 1000 FPS or more would be great to draw patterns.
I have already set MIN_SHOW_DELAY to 1 so if I got it right the service function should return every millisecond = 1000 FPS
Does anyone have an idea what is causing this delay?
Clock rate of the ESP32 might need to be higher to achieve 1000 FPS.
Might be the max rate a digital output can toggle - check datasheet for your specific ESP to be sure.
Looking at the standard neopixel details, 31 LEDs is ~ the maximum that can update at 1000 Hz.
This assumes RGB (not RGBW).
Try changing the # of pixels to 30 and see if the frame rate shoots up.
Did you ever have any luck running closer to 1000 FPS?
