Ok, I have a fix for this on github.
Please try the latest version and see if it works better.
OK, I have re downloaded the ProffieOS-master from GitHub. (if this was incorrect please let me know). It looks like it has come farther along.

You need mjpegtools. (brew install mjpegtools)
Thanks. I have a proffie produced idle.pqf . I will try to light the saber this afternoon, gd I hope this works haha.
I appreciate everyone’s help. On a different note, POV is awesome. Good workout too.
Hopefully last question. I am testing using idle.pqf . I understand that this should play automatically. Do I need a corresponding .scf file for my pqf to work?
Thanks
Seems unlikely, you’re just getting to the point of making this work.
Once it works, you’ll probably have more questions, which would be welcome.
Yes. Otherwise it wouldn’t know what layer to play it on.
The PQF files can be called whatever you want, and may be shared between SCR files, or you can just create exactly one SCR file for every PQF file.
So close but so far away. Using the proffie created .pqf, I created my own .scr with one line. file=idle.pqf . both in the font in a folder named 9x9. Here is the serial.

- make sure you have a newline after your “file=idle.pqf” line.
- What does your actual config look like? I assume you’re using DisplayStyle<> ?
Its working. Not yet readable, but I think I can get this to work this weekend. Thanks
That was fun. Thanks Fredrik and Brian for helping me along.
Need to work on the text. “Hello World, this is Proffie”

I have this text “font” image collection of lettering if it helps
https://www.dropbox.com/scl/fo/3eghtwi7ou2xbu0qrm8wb/AH9euUBZ2cXZVvLbUv9oeWI?rlkey=kpnpz6delh8j0hyq7zqoqfzvr&st=9rcw7klp&dl=0
It may already exist but I wrote a python program that creates scrolling mp4s that I used to generate scrolling mp4’s for cpqoi conversion. I updated it to incorporate Brian’s font styles if anyone else is playing around with different matrix. It generates as a perfect square now, but can easily be modified to any display layout.
Can I play a .pqf and .scf from the common folder, or does it have to be in each individual font? Thanks
They can be in the common folder if you like.
Here is a text font letters in BMP images I’ve created specifically for dot matrix like the round 69-pixel one:

Hello
i want to install the same 69 pixel shtok blade plug and all your and profezzorn talk was very instructive but i have two questions for you:
what is your blade config (SubBladeWithList )?
what style to you use to play the SCR and PQF file?
thanks in advance

I used Dim Blade but you do not have to. I just used the pqoi tools in the proffie OS. I learned to use Python to create the animations. The subblade setup only currently works with the Proffie Master so not an official release, but don’t know if it will be included in OS8. Do not be intimidated by Python. I taught myself how to use it in an afternoon and have written a few programs already. It just takes some patience. Hope this helps.
Thank you for the answer but I am not aware of what is proffie master
That’s the current/latest work in progress that you can get from the Github website.
Go here, click the green CODE button, and download zip. Use that ProffieOS as your upload source.
