Dear pylon
I really appreciate your enlightment
pylon:
Unfortunately this doesn't get clear from the article. I would just try and attach a scope to two pins. The scope output will show you quickly which are the right ones. Probably this changes from one drive manufacturer to the other, so you have to check anyway.
Well ... I remember some one give me NanoDSO, but I never learn about it yet.
But internet lead me back to this forum, specialy :
http://arduino.cc/forum/index.php/topic,16497.0.html
I will work from there.
Sincerely
