'lat,lon,alt' is better, but it is actually 'lat,lon,herror,alt,verror,time' and a lot of other metadata... Also, we already have driver for GPSes, its called gpsd. I'd leave GPSes out of input. > Also, GPS, liek ALS, would probably be polling, no? Normally, GPS just sends you position info once a second. -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
