Help with Sabertooth 2x25
April 23, 2010
Hey everyone. I am building a couple of projects using electric wheel chair motors. I am using the Dimension Engineering Sabertooth 2x25 motor controller. The proble I have is I am sending pulses of 1000, 1500, & 2000 us to the sabertooth and am getting random results (both forward, one forward the other reverse, both fast, both slow, one fast & one slow, etc) with no apparent consistency.
I am using the controller in RC mode and the signals are being sent from a BS2 microcontroller. I hooked up my O-scope and saw the correct pulses, so I don't think that is the problem. I also grounded both the BS2 and the sabertooth together on the signal side. Could this be a bad sabertooth (its brand new!) Am I sending the wrong signals? I am at a loss here cause this was supposed to be easy and I THOUGHT I knew what I was doing.
Can someone with experience with this controller help me?
