    yes and no. Do to reasons I had to take down my pcb board and DIY kits, however the github code and forum posts and occasional help is still there. If your good with combining wiznet schematics to teensy and the octows2811 your pretty much the same level as where I left the project.

    Hi! Ok looks like your getting buffer info! thats good! Looking at your setup the way we need to think of this is budgeting the correct pixel per port settings. since you are using 300 pixels we need to use the correct universe budget. To make sure the buffers are setup correctly we need to...

    I use tycommander to detect my teensy boards. It has the ability to detect the teensy serial number regardless of what port it’s in. tycommander can output json format of board details so you can easily adapt to your coding preference on the pc.
