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.

| (...) You've got a point here. What if we hardwire STATE_0_VALUE to the following? #define STATE_0_VALUE (ds_unscale(1023U)-RANGE_SIZE) Or, for a more general approach: #define MIN(a,b) (a<b?a:b) #define MAX(a,b) (a>b?a:b) #define STATE_VALUE(k) ( \ (...)
