thx for that help =)

*feeling very n00b...

jst wanna confirm:
we're using an L6203 for each H-bridge, which has 1 enable and 2 
inputs. Am i right to say that the two inputs change the direction 
of the motor?
as in, if i put the PWM into input1, it'll go one way and vice versa 
if i put it into input2? I can't seem to find a good ref which has 
this explained clearly...

and, if this is the case.. how could I configure the other ports to 
change the direction?
