Rotate
From Openmoko
Here's a quick and simple C program that reads a packet from the accelerometer once per second, and rotates the screen to a new orientation if the orientation has changed.
I don't mean this to conflict with Paul's excellent work on Gestures; my reason for writing it is so that it can be used as an always-on daemon in the OM distributions. (Full gesture interpretation is more CPU heavy and requires reading data more often than once per second, so perhaps that will be done on-demand instead of always-on.)
The code is:
http://github.com/cjb/freerunner-rotate/tree/master/rotate.c?raw=true
There's an ARM binary here (chmod a+x rotate && ./rotate):
http://dev.laptop.org/~cjb/rotate
And you're welcome to make patches against the GIT repo here:
git://github.com/cjb/freerunner-rotate.git
Would anyone else be interested in being the maintainer of this package? It would involve packaging it up in bitbake/OE and trying to persuade the various OM distros to include it by default. (Perhaps with an on/off control panel entry in distros that make that easy to do?)
Comments appreciated. Thanks!
