I had a working setup with this lighting rig I created and now it isn’t working. I know the rig is ok, because if I just give it explicit commands on the chip it’s fine. There is something that no longer works (post re-format, I might add) on the serial line.
I was always confused about the ‘serial a’ object I created. Is it possible that my computer now thinks of my USB ports as a different serial port? How can I find the name of it?
If you look at the object’s helpfile, there’s a debug method for listing available ports in the Max window. You send the object a message – I think it’s "print" or "ports", I’m not at my pc right now. Then choose from that list til you find the right one. Doing it from the Arduino IDE or your OS is dependent upon your OS.
