Pypilot with ST4000 autohelm

[ironman]

As for the inverse signal I guess you are handling that using the 3.3V instead of ground - right?

You got it.

By the way - now that we are on the st4000 topic, I made this remote some years ago and I absolutely love it. Instead of the IR a udp, tcp or Bluetooth can alternatively be used connecting it to your smartwatch or phone which is so enjoyable.

As for the PCB part you can get that manufactured for a couple of dollars

Sweet! But if you can build that, then you can also build a pypilot ;-)

I had done something similar, btw - not wireless though https://github.com/marcobergman/remote_pilot. Your code is way better - I never bothered with checking for collisions on the seatalk bus.
