I've noticed this time is not so predictable. I did not take a look in the driver, but when you rotate 90 deg suddenly, it takes a while before the next sample is ready. Maybe some averaging is done in the kernel

really good! thanks! I will certainly use it in the future!(within an other apps..)

icon and .desktop file

I have made a small icon for this app.

Waterpas

Tell me what you think about it - i'd be glad to see it as the app's default icon.






Here's what my /usr/share/applications/gwaterpas.desktop looks like:

Encoding=UTF-8
Name=Waterpas
Comment=3D sensor
Exec=gwaterpas
Icon=gwaterpas
Terminal=false
Type=Application
Categories=Utilities;Utility;
SingleInstance=true
StartupNotify=true

Would be interesting to add resolution/accuracy informations to this wiki page. -> what should be expected to be measurable (how many degrees) -- cberger

resolution/accuracy

I understand that applying a logarithmic conversion would be interesting. The linear behaviour is somewhat 'brute' in de range that really matters. The linear behaviour makes it especially useful for easy sensor monitoring.

The jitter that exists on the input sensor did hold me from doing so. Taking averages might help. Conclusion: I did not do this yet. Don't know which one to favor: speed or accuracy

How long does it take to get one value? If you just take a *few* samples, the delay won't be that bad and the jitter will reduce a lot I think.

Btw. I'm going to add a SHR/Illume-Button to the icon and change the "main" gradient a bit, as soon as I have some time. Could you include both icons then (so it can be changes by a single char in the .desktop file)?
