Thanks for any insight!
I have MPU9255. My free autopilot
reads from this (and other) sensors and performs fusion and automatic calibration. The autopilot
server has a simple client daemon that translates the signalk from the autopilot into nmea for opencpn
This feeds opencpn
and roll, and magnetic heading data, and receives autopilot route
The autopilot also can receive nmea wind
, and relay it to opencpn. The autopilot runs gpsd as well, so steering
to compass/gps/wind, or fusion of these is possible.
It is also maybe possible to use openplotter if all you want is to display magnetic heading in opencpn from i2c sensors, but I don't think they have the automatic calibration I have, so the result would be worse.
Furthermore, you would never want the autopilot to read the data from openplotter instead of directly, as this would add latency in the gyro->rudder feedback loop.
