How do I hook up my Raspberry Pi (or ESP32) to the NMEA input on the Raymarine controller? Do I just use the tx and rx pins? And how do I make Openplotter recognize the pilot? Also, is it possible to use an ESP32 as I would avoid all the wirering..?
If you have an openplotter pi hooked up to your gps and windvane already, you would not need another autopilot. Just hook up the pi where openplotter runs on to the nmea wires of your ST4000 using a nmea 0183 to usb adaptor. Configure the connection in opencpn to forward the right nmea messages (APB, RMB, MWV?) to the usb interface. Then, when you activate a route ('track') in opencpn, the autopilot will follow that track if instructed.
Building a pypilot is for those who do not find raymarine 'acceptable' ;-) it really is quite a bit more work, you know.
