[Linuxwacom-devel] libwacom new data file 'make check' error

[Favux ...]

I'd appreciate some help on this one.  I do not know why I am seeing
on 'make check':

lt-tablet-validity: tablet-validity.c:94: verify_tablet: Assertion
`nstyli == 1' failed.
/bin/bash: line 5:  8362 Aborted (core dumped) ${dir}$tst
FAIL: tablet-validity
===
1 of 3 tests failed

>From this .tablet file.  It's the first of the 3 and they all seem OK
to me.  Don't understand why the stylus is flagged.

Re: [Linuxwacom-devel] [PATCH 1/1] Use kernel-reported tilt range and resolution

Hi everyone,

Make kernel driver report it. Make kernel driver report zero-centered

I've had an opportunity to measure reported tilt values of a Wacom Cintiq
12WX today. It wasn't a very precise measurement, but it still showed that
the reported values are much likely to be *sines* of the angles and *not*
*degrees*.

This matches what Waltop Sirius is producing, which is quite expected,
considering they seem to use the same pen technology.

I've attached my data, along with an OpenOffice.org Calc spreadsheet
containing a graph of angle fractions vs. sine fractions vs. fractions of
reported values.

I'm not sure what to do with this, yet.

Sincerely,
Nick
