Exactly. I don't have rotation sensors, either. I think these values
were originally gathered from Michael Nielsen's sensors.

What's the current status? Is there a patch working for everybody, or do
we need some calibration work? It would be fairly easy to write a little
program that transmits rotation sensor values while the user is turning
the axles. A small host-side script could segment those values in four
regions and take their respective medians, generating a user-specific
configuration file. But I suppose this would be overkill, as LEGOs
sensors are supposed to work for everyone.

I suppose we could ask for help also to non-legos owners of RCX and rotation
sensors. What if any of us posts a message in the robotics newsgroup asking for
some reads of rotation sensors? Raw values can be read with the sandard
firmware too and then we will scale them. With a set of values a bit larger
then mine we can probably set up legos constants to make them more general.

(...) Why doesn't somebody finish up the decoding of the ROM, specifically the routine at 14c0. This routine takes the raw sensor samples and converts them to usable values, including handling the temperature and rotation sensors. The standard (...)
