Re: [Gumstix-users] Robostix for Newbies

[Nick O'N. <aut...@gm...>]

Fair enough, I'll get it started.
I'm looking to use a small motor controller from Pololu
(http://www.pololu.com/products/pololu/0410/) with some small dc
motors. This diagram
(http://www.pololu.com/products/pololu/0410/dual_con_big.html) shows
the inputs and outputs of the motor controller. I understand the
positive and ground input as well as the motor outputs but I'm
confused which vcc from the robostix I should use (there's a whole row
of them labeled as 'interupts' and 'port c' on the robostix - I have
no idea what either of those really *mean*) as well as the two other
outputs from the robostix (labeled as 'serial control' and 'reset' on
the pololu diagram). Once we've solved that question, how do I access
them from the robostix code?

Hopefully that helps explain where I'm confused :)
