Always simpler than I anticipate, you guys have done some incredible work on this project, I got up and running so much faster than I expected! Thanks for your help!
Follow up question, I can now address all 576 LEDs properly over the serial adalight connection, but the latency / responsiveness appears worse than the WLED UDP connection. Is this just a reality, or can I increase the baud rate or do anything to reduce the latency over USB?
