Since I’ve been rolling my own sort of controls, I never really thought to ask this question- is there a DCC sound unit that I could interface to an Ardunio sort of microcontroller? In effect, send the DCC commands from the micro via bit banging or serial or whatever, into the sound controller? If so, would it operate at standard logic levels (5v) or would I have to somehow bump that up to track voltages? Just wondering.
