Thanks Bob, sorry I forgot to say thanks when I first read your
post.
I did get the 7774P to work but your suggestion looks like a
better breakout unit for experimenting, for sure.
The link I found for the Sparkfun unit had more features
in the breakout so you could select the step modes as well.

I'll get one of those, thanks mate.
