As well as David, I was thinking about purchasing an Aspirin
for my tiny/twog. Good to know that there is not driver yet(and unfortunately my
programming skills are not good enough to think about writing the driver on my
own). What about the arduimu? I think it has a micro inside and is
not the same concept as the razor imu(which sends directly the analog info to
the autopilot adcs). Is the arduimu easy to have ready to fly? What about the
calibration process? Anything more than modifications in the firmware section
of the airframe file needed? Felix, I’m still not flying with the razor imu. I have
compiled a branch which runs on tiny 1.3(I’ll try with the other one
which runs with twog-the last time I tried it I got some compiling errors), and
I see an strange behavior in the PFD(when I roll the airplane, the PFD shows
the right angle, but then, if I move the airplane horizontally back(0 roll
angle), in the PFD it is moving slowly, and it takes some time until it is
reoriented). And using the razor imu with the main branch software has been
until now impossible(now again, my skills are limited). One thing more, these days we have experienced bad GPS
accuracy here in Madrid(midday, February, Tuesday 24th), do you know
if there is any GPS problem? I read something about US GPS accuracy limits due
to Army tests…are they still going on? Ana |
