interesting
i wonder if we could hack something together using the wiimote drivers to give similar results.
tape wiimote to bottom of 810 and see if it works, or plugin one of the mini usb ones ive seen knocking about.
i doubt we could replicate the dbus part, but the sysfs portion looks feasible for a fake driver to supply.

I have compiled the app for X86 to test it in the SDK, but it fails with a nice core dump:
Code:
ERROR:sand.c:285:main: assertion failed: (dbus_proxy) /usr/bin/run-standalone.sh: line 11: 23643 Aborted (core dumped) "$@"

Might be best to look at the kernel code and see what the driver does (assuming we have the relevant bit), apparently the scaling, etc., to produce a value in milli-gs is done in there.

But depends how the system use it

Ya know, if the next NIT has an accelerometer in it, I'm so gonna be stoked. That in itself has so many uses that I can't even name them all.

Hi, yes I published that page yesterday but then I went for other things and forgot to link it somewhere.
Basically is the best I could get to answer a question that was coming from the NumptyPhysics developer and others. Hopefully a better interface and documentation will come, but in the meantime you have the basics there.
About the little app, please contact marnanel directly. I'm sure he is willing to share his own findings but I don't expect him to be aware of this thread here. I have seen the app working but that's all I know about it.

Ah no worries, just looked in the patch. Take a look at the following file: /drivers/i2c/chips/lis302dl.c

All times are GMT. The time now is 05:11.
yesterday appeared a page on the maemo wiki about the accelerometers features in fremantle. In this page is suggested a example application, and a deb file (compiled to arm) is provided.
How should we use it ?
Since I'm very interested in the accelerometer features of fremantle, I have a couple of harmless questions (if this information can be disclosed now).
Is possible to set/get the sample rate and threshold via sysfs ?
The accelerometers d-bus code is OSS or will be ?
Thanks.
