Basically instruct the user with some pictures what to do. It requires some AJAX to get it life, but I guess the code for that must be somewhere around.

			No reason you couldn't do it in the camera, and using PHP if you wanted, but in some situations it would be nice to be able to get high update rate (10 Hz or whatever) from the compass without having to transmit images as well. If the camera could bridge the net interface to the serial port this would be trivial. But that's the really nice thing about open source, people can implement many different methods.

			You guys love PHP don't ya ;) I'll see what I can come up with.

			Why not doing it from the camera ? It's what we did the first time we got the compass. We calibrate it via the serial port with some special commands. It is possible I think to build a PHP app that will launch compass calibration on request from the browser. So the user will only have to manually rotate the camera.

			FWIW, the compass does support hard-iron calibration via simple serial commands plus manual rotation of the compass. See [http://www.ocean-server.com/download/OS5000_Compass_Manual.pdf ocean server compass manual]. This is similar to other compass modules. It would seem that this is an application level procedure and not really suitable for embedding in the camera. It would be nice if the camera did allow for a redirect of the serial comms to a network socket or something.

			On IRC I heared there is no calibration on the compass. So probably it only gives lets say the rotation it makes like a gyro does.

New page

You are using the ocean server compass?

Are you using the depth sensor as well?

There is no calibration SW? or just no linux SW?
Would you know if there is depth calibration SW?

I would guess that the elphel should just be able to parse NMEA-0183, then it
can work with most compass modules (KVH, PNI TCM-2, etc.)
