Hi guys!
I have a GPS module with built in compass. It's a serial GPS unit and used I2C as the compass.
I can get GPS working no problem, but can't for the life of me figure out how to get the I2C onboard compass working.
The unit has 6 wires, power, TX and RX for gps serial and SDA and SCL for compass
An i2cdetect 1 -y returns one positive device at 1b.
Any ideas?
Thanks

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

I will have a look there, but I did do a i2cdetect 1 -y on the PI in CLI and it shows in there. If I remember correctly there used to be really limited support for I2C sensors.

So I checked I2C settings tonight, Yes it shows at an I2C address but again, none of the devices in the dropdown are compasses or even compass related, they are all Pressure or current sensors.
So since 2 years ago when I tried this, nothing has changed. Still there are no I2C supported compasses.
This leads me to my next questions, what is everyone else using as a compass to get a heading?
Cheers
