Hi Manny, sorry but I don’t think anyone is running Aurora right now. @Jason is working on other awesome non-matrix projects (check out his Twitter) and not maintaining Aurora anymore. I’d like to get Aurora compatible with the latest code running on SmartLED Shield for Teensy 3 and with the upcoming SmartLED Shield for Teensy 4 where a 128x128 pixel Aurora display might be feasible, but it’s not a project I can take on right now, sorry.
If you’re trying to compile on really old versions of the IDE/Teensyduino, you’ll need to roll back SmartMatrix Library, and then you’ll lose support for SmartLED Shield for Teensy 3 V4.
Your best bet now to get some of the content of Aurora running on your panel is using this project: Announce: SmartMatrix::GFX - #2 by marcmerlin
