Serial GPS and I2C Compass

[deanfourie]

I remember posting here a few years back with the same issue before giving up the goose, another issue with compass support. It seems this issue is avoided in OpenCPN now for some time. Not sure if there are problems getting compass integration working, but no one has ever been unable to provide an answer to my issues with compass support.

How is everyone else using compasses with OpenCPN?

Thanks

What model gps/compass is it?

The 'HDT' nmea0183 heading message works fine in opencpn

Well I dont think im getting any HDT messages. I think its a UBLOX chipset cant tell you exactly what model yet, but it has six wires, 2 are power, 2 are TX/RX (GPS) and 2 are SDA/SDL (Compass). I cant get the heading working at all in OCPN. So, am I going down the right track in thinking this should be a compass connected via I2C or should I be looking more at getting HDT messages from the GPS itself?

Thanks for your reply.
