Re: latest FSO from debian/sid not working
Can you describe the problem? - no apparent reaction to key presses -- no action (suspend or so), no line in logs (everything set to DEBUG) - no led action - persist/ folder missing (frameworkd complaining about it and throwing an exception) - files in /sys/ missing (i'd expect the fso in debian to work with the kernel there -- or is it just the usual discrepancy one encounters in sid now and then?) i updated to 2.6.39.4 from SHR, and at least the files in /sys/ are back -- but nothing else changed. i got rid of LXDE (tested it years ago and never was happy with it) and installed e17 -- but even without any X, FSO should do something when pressing buttons at least. do i need any more modules loaded? i rather foolishly purged my old debian installation without saving configurations and stuff, before i tried the install.sh. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

AFAIK the driver is not yet includet in the gta04 kernel, but this is a minor problem and can be fixed quite easily. The driver for the accelerometer is also not yet included. You will need it to get tilt-compensation. There exists a simple hack that reads the raw acceleration values from the chip and delivers them to userspace using a sysfs file, but it's not a real driver with a standardized interface. With these two chips working, you need a piece of software to calculate the tilt compensated heading from the raw compass and accelerometer readings. Maybe "valacompass" (http://wiki.openmoko.org/wiki/ValaCompass) can be modified in order to get the desired results.

Re: Advance OpenStreetMap surveying with GTA04?
Hi Liz, Yes you are right 8-( The issue from a GTA4 point of view is that I would need to load one dataset more in the GTA04: both new and old OSM datasets. Or maybe merge the datasets and build a map suitable for GTA04, clearly showing the licence status... From OSM point of view (so maybe better to continue off-list) I should check with JOSM licensechange plugin [1] everything around the path. Some highways (roads, tracks, some paths) should be visible from Bing and Italian PCN. Yet another thing to add in my TODO list for the ViaAlpina. If you want to help ;-) I've put a dedicated TMS for this here: http://www.outdoormaps.org/?p=39 Cheers, Mayeul http://wiki.openstreetmap.org/wiki/JOSM/Plugins/LicenseChange - Mail original - De: "Liz" À: community@lists.openmoko.org Envoyé: Lundi 19 Mars 2012 06:52:44 Objet: Re: Advance OpenStreetMap surveying with GTA04?

This will alter what is in the OSM database, and you should have access to other maps under these circumstances.
