Hi,
Has anyone tried using the standard NXT Ultrasonic sensor calibration settings?
I've been doing a little work on the leJOS i2c interface and although I can read
both the factory default values and the current settings I do not seem to be
able to change the current settings. I suspect that the Lego documentation may
be a little out here (for instance the doc claims that the current settings are
at location 0x50, 0x51, 0x52, but I think they may actually be at 0x4a...). Has
anyone actually ever changed the values?

Oh and I've been able to write to (and verify by reading back), other settings
(like the continuous ping frequency and the command mode), so I don't think it
is anything wrong with my write code (unless there is something different about
the registers/locations used for calibration)...


Thanks

Andy
