Falcon Player Plugins / Re: Feature Request: An Alexa...
Last post by Doctor Wizard - Today at 10:00:29 AMI haven't tinkered with any of them (yet) but there are a number of different techniques for sending Alexa commands and running routines from the Linux shell (or Windows command line). Initial setup and configuration seems like a PITA tho.

Falcon F16v1 / Re: Newbie question on connect...
Last post by JonD - Today at 09:20:12 AMThanks for clarifying Daniel. That makes perfect sense. The controller issues make sense to me. I was having a hard time getting my head around why FPP could not handle 40FPS, and it turns out I just need to get a new pair of glasses! 
Thanks!
Thanks! #3
Falcon F16v1 / Re: Newbie question on connect...
Last post by dkulp - Today at 06:53:22 AMThe various Non-Pi/BBB remotes (Falcons, Genius, ESPixelStick, etc...) may have various hard limitations. Those limitations could be due to a variety of reasons. It could be the CPU speed on the embedded processor. It could be the way the SD card is wired limiting the amount of data that can be read off. It could be amount of memory on the device. (The latter is the reason the F16v4/5 only does zlib, not zstd. zstd needs larger memory look up tables to decompress). Theres a bunch of reasons. But in pretty much every case, the limitation can be "removed" by sticking a Pi in front of the device to act as the remote and leaving the controller in "bridge" mode.
The Pi's and Beagles certainly have limitations as well, but they are way beyond what any of the various standalone controllers support. As mentioned in that thread, the SD card on the Pi's and Beagles are not super fast (compared to the SD card slot in a modern computer). However, using the zstd and sparse FSEQ files almost always keeps the size well below those limits. The single core on the older Pi's and Beagles certainly limits things, but it's fast enough to handle any of the capes/hats that are put on it (exceptions being the K128 and the Octo's). In general, those limits have nothing to do with the frame rate though. Once you get to 40fps, if you haven't hit those limits, you are fine. Going from 40fps -> 100fps, for example, means the strings lengths have to be much lower. Thus, the amount of data per frame is much lower.
Anyway, the Pi and Beagle based controllers (and the Pi/Beagles's in general) will work fine with pretty much any framerate. I've tested from 20fps up to 120fps for various configurations.
Can a single Pi3B+ handle playing a 4million channel show at 40fps all via e1.31? Likely not. It could hit the SD card speed limit(likely in complex areas of the sequence). Could hit the network limit (probably, Pi3B+ ethernet is via USB2 which the soundblaster would share). Etc... However, the nice thing about FPP is you can add additional remotes and split up the heavy loads to keep what each Pi needs to handle to a reasonable load and eliminate the pressure points.

Falcon F16v1 / Re: Newbie question on connect...
Last post by JonD - Today at 06:28:30 AMMaybe that is where I had got lost. I suggested the standalone option was not ideal and threw out installing a Pi in the controller box. I probably moved on to the Pi and others were still talking about the Falcon.
So what I am hearing is that FPP BB and PI should fully support 40FPS, but some controllers when placed in remote mode may not be able to handle 40FPS. The tiny cpu and SD card read latency on some controllers may cause them to drop packets?

Falcon F16v1 / Re: Newbie question on connect...
Last post by darylc - Today at 05:42:10 AM@JonD The thread you linked was about Falcon v4/v5 running as remotes via an SD card. My comment was related to that, it had nothing to do with FPP controllers in general.

Last post by JonD - Today at 05:11:02 AMQuote from: dkulp on October 03, 2024, 03:18:45 PMHuh? All the Pi's should be able to handle 20fps and 40fps just fine.The original message was linked above. Someone suggested the Pis would not do 40fps in multi-sync, I had posted I thought they should, and then Darylc and you posted there were some performance issues with reading the SD card.
There clearly is some information out there suggesting FPP cannot handle 40fps in some circumstances. Just trying to get my head around when that is. Where does the SD card performance issue come into play... if at all?

Falcon PiCap / Re: PiCap V2 Manual
Last post by hak715 - October 03, 2024, 07:39:40 PMThank you both for your responses! I just received the PiCap and have it up and running, super easy! So far so good. One thing I noticed, the PiCap option in xlights only has 2 ports. What controller type do you use in xlights to use all 4 ports on the new PiCap?
