Nate, Stephane - thanks for the pointers on working with CVS code. My
excuse for not reading the README.developers is that in no way do I
consider myself a developer :-) But I read it, followed it, and got a
successful compile.
Nate, here's some results from the latest RotorEZ code.
You'll note that while most things are looking pretty good now, there's a
offset between what's sent to the rotor, and what's received back. I
don't know if that's just conversion error or what. It does seem to get
larger as the azimuth gets larger. That could just be linear error in the
direction resistance coming down from the rotor, though..
I'll do a little more investigation when I get into the shack, probably
tomorrow. (I'm doing this from work - putty is your friend :-D )
