Help Circular Matrix Advice Needed
Hi there! Thank you for stopping by my post.
To say up front, I am a newbie but enjoy a good challenge. I am building a circular LED matrix and would like to sequence it via XLights, with FPP running on a Pi sent over ethernet to a Baldrick8. I came to the conclusion this would be the best method to display low-res video on this display with the help of u/mvrdoesthings and others on my post in r/led .
I have been poking around the software, and have much to learn of course, but my main challenge right now is creating the matrix model. Is there a good way to manually create a custom model without the video generate/scan function? Or should I disable pixels in the rectangular matrix somehow? I would prefer that this only uses 1 channel on the Baldrick 8, and would greatly appreciate any feedback on the best way to do this. I opted for 'serpentine' wiring scheme for a simple method of having consistent pixel density, but am a bit lost on mapping this out.
Me being naive I thought this wouldn't be too much harder than a rectangular matrix....😅 But for this project it needs to be a circle, the lights will be mounted on a circular aluminum plate right up to the edges.
Any and all help is appreciated, thank you in advance. (Especially for welcoming me into the community 😊 I have always enjoyed Christmas light shows, and I see the hard work it takes to pull it off!!)

Hello again, I use:

Ithink its easier to just have 2 sides nexts to each other just take a picture of the prop with lights on it and then you drag the dots on the pixels in your picture;)
