This is why I am a fan of the Teensy3... It's a Freescale micro based on
ARM cortex, and fast, low power, etc.
However, I happened to have an Arduino sitting in front of me on the table
on Saturday when this started.
The computer you've got is better than the one you have to order and wait
for.
Thanks for the pointer to "teensy3" I did not know they were using ARM.
they are very cool..
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 suspect it would. I'm running a 50 MHz teensy3 and a pair of 19 tap
FIR filters at 200 Hz (actually after decimating from 50kHz, but the two
stage decimator is an integer CIC type).
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.
yes.. and that runs on a teensy, as well.
