Yes today use what you have but if this really is going up in battery powered payload you'd buy the part that works best. I'm using what I have now but I see it is not going to b the longer term solution. Your Teensy looks good. Thanks for the pointer to "teensy3" I did not know they were using ARM. I'm going to look into this because I'm adding a Kalman filter in a project that is now Arduino based It's working out to be a 12x12 matrix. I'm not at all sure the little AVR chip and do floating point math fastest enough to run a Kalman filter that large inside a even a slow 1Hz control loop. I was thinking I Wanted Beagle Board Black. But if the navigation Kalman filter and motor control PID loop fit on a Teensy I've by better off. Eventually I need something that can run a real-time version of Linux. Back on topic: Arduino contributed code includes a Time library that can input time using NTP over Ethernet and from the German version of WWVB as well as a few other methods of time transfer. So there appears no need to re-invent time transfer into an Arduino. > > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/ > mailman/listinfo/time-nuts > and follow the instructions there. > -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
