Has anyone gotten the honeywell HMC5883L 3 axis magnetometer/compass working with the beagleboard? (hopefully the bone).

Yes, but I did not use kernel driver, but talked to it directly over i2c.

do you know of a kernel driver for it? can you reference any good code or other references that helped you make use of it? Really wanting to use it as a tilt compensated compass.

Thanks,

Eric

I used the best reference you can get: the datasheet :slight_smile:
The chip is quite popular and there is a lot of code floating around
on the net. I think I read about a kernel driver, but never tried to
use it.
To talk to the chip, I use korebot i2c library:
