Aram, measuring torque on an AC servos is definitely possible. It is not as simple as measuring current but this does give some feedback. I don't think that the current used by the servo drivers is a measure but you try Stan's setup that way. There are servo drivers with force-feedback but I an

It becomes a pain to keep juggling functions around to avoid this problem. Better to declare all functions at the top of the file with a prototype, like I suggested. Then you don't care about the order of the functions. Andy Kirk Wallace wrote: > On Tue, 2008-02-12 at 15:36 -0700, Andrew Ayre
