I'll be honest, I havn't used IC3.anything, so I don't know if that
would be a problem (I doubt it).
I don't know if you saw the mail I sent out last week or not, I made a
mistake in the schematic, and the M/S pin needs to be grounded to get
the compass in master mode.
The interrupt routines I wrote do suck a bit of life out of the HB,
with the compass running at full speed (5Hz updates), the CPU will
spend a couple milleseconds handling the output of the compass.
I guess I have never had the compass crash the whole CPU though.
