Falcon Player (FPP) / Re: Limit for GPIO pixels
Last post by Poporacer - June 18, 2025, 07:13:49 AM
There are a few things that determine the limit, but the largest one is the WS2811 protocol. The data signal for each pixel has some predefined pauses in it. If you send the next signal packet before the first one has been processed, it will cause tearing where the lights are not changing at the same time.
The other issue will be voltage and data loss, but that is a different topic.
The theoretical limits can be calculated using this:
Max Pixels per port= 33,333/FPS
So, if you are going to use 10 FPS, then you can theoretically control 3,333 pixels per port. The Pi will use up some of those pixels in the processing and the Pi-Zero has very little processing power so you will likely get less than this, but probably close.

Understood, but this application may be able to live with less than 10 fps.  Id these a hard limit?  This will not be a Pi HAT.  I will drive the pixel strings directly (through a level shifter, of course).

FPP puts a limit of 1600 pixels per port (2 max) for a pi hat (which is gpio based output). WS2811 is also limited by frames per second. Forty FPS is about 640 pixels per port. Twenty FPS would double that. 

If you are not using FPP, you might get longer strings but FPS would have to go way down.

Falcon Player (FPP) / Limit for GPIO pixels

What is the hard node limit for pixels directly controlled by a GPIO pin on a Raspberry Pi?  A client is looking to control some WS-2111 pixels directly from a Pi Zero-W, and we need to know what the maximum number of pixels is so we can scale the strings accordingly.

Well after much hassle and some prayer - I upgraded one more time to v8.5.1-15 this morning and after some continued messing around it now seems to work.  I've added all the output instructions and they seem to be staying and the Abnormal Error message is gone.  I'm feeling a little unsure that it'll continue to work correctly, but it's working good right now.

Thanks to you guys for trying to lend a hand.

I'll likely need to get one or two of these panels in to actually diagnose the layout.   I did just add a 32 zig zag option (and 40 zig zag for P4's) to master branch as I noticed they were missing.   This semi looks like the 32zig zag, but setting to 80 really makes the picture useless as that's not any multiple of the panel sizes and thus would screw up any attempt to diagnose things from the picture.

Again, getting a panel to me for a few days would definitely get them working.    You have all the "parts" of the pattern displayed so it's just a matter of mapping the placements.   This isn't like the new PWM panels that wouldn't be displaying anything.

Ok, I've got. a working version with a ,,Color Fade" overlay effect now. Unfortunately the effect only uses rgb instead of rgbw of my stripes. xLights can use rgbw wich does look better. 
If someone has a creative Idea to utilize the xLights power, this would be very welcome.

What I didn't mention so far. I'm using fpp currently not for a great light show. I just want to control the lights in my home cinema with it. Switching lights on and off and setting the color just works fine with the HomeAssistant plugin. But I hoped I could achieve cooler on/off effects, if I utilize the xLights capabilities. E.g. fading out the lights from front to back in room if a movie starts or just a smooth fade out instead of switching them off instantly.

Quote from: allknowing2012 on June 11, 2025, 01:21:14 PMThere will always be a reset/off after a sequence. No way around it - best you can do is make the sequence longer so as to reduce the number of times it does that. A totally different approach might be to just start a wled effect on fpp - that way it stays running until you turn off the fpp command. (not using xlights at all in that scenario)
I also tried using a Wled effect on fpp already, but I couldn't find one, which just fades in and keeps the lights on. I think there was just an effect, which fades in with a period of time and fades out again after.
Anyway, I would prefer to use xLights, because of the flexibility of the effects.

I want to control the behavior of the lights with the api. Can I set the overlay state to on, start the effect and just don't set the overlay state back to off afterwards? I maybe can try this later today.

You didn't set the arrows in the correct order. Thes panels are a bit confusing because they have double arrows. Try turning the arrows to the left
