  • Yes, you should at least get something. .write is more reliable with Uint8Arrays but it should at least make things go random colours the way you have it.

    Also if you just lower the voltage you use to 4v then even without the resistor and pullup it should work.

    Given this is a custom board, if you had the clock settings set up wrong then possibly USB would still work even if all the peripheral timing was wrong?
