Starting Data still not working? #5

Seeing weird behavior. On a cheap 24 channel light board when I send data on 7 channels I mostly get good data. However, when I put values on the higher channels I get random junk.

When I connect to a big light board I get all kinds of junk data in the read values.

I don't know for sure, but it looks like the packet start is not working.

How can I diagnose this?

You can try https://github.com/luksal/ESP32-DMX-RX which uses the ESP hardware break detection feature and hopefully is more stable. At least with my circuit it works on grandMA2 and a cheap 48 channel light board.
