never mind - I tested my patch again and noticed that the driver wasn't able

getting any data (I am simply disabling the extension when not getting
proper calibration data).
Thanks! I have both patches ready for submission. However, could you
actually tell me in what range data is submitted? As I said, I cannot
test these patches. But looking at the code, you get 16bit per value
raw input. You then calculate the per-kg value and multiply it by
17kg. So I guess you fill up the whole 16bit?
Your second patch does not adjust the MIN/MAX values for the ABS_HATXY
values and I am just looking for good values here.
OK, I see - the advertised maximum weight for the balance board is 150
kg. In theory, that would mean that every one of the 4 sensors can take
up to 150 kg (if a very heavy person is standing on one foot right in
the corner), which would translate to an absolute maximum value of
15000. In "unweighted" state, my balance board reports slightly negative
values for some sensors, so a minimum of perhaps -500 would be appropriate.
Thanks for integrating my patch!
Florian
