Subject: [alt-beam] Re: Microcore, and Motor Driving
If you download the datasheet:
http://www.geocities.com/SouthBeach/6897/extras.html
It tells you what the dir pin does.
My Walker 2.2 schematic has the dir pin going to positive which is wrong for the
shown orientation. The correction has been posted for a while.
I really suggest everyone get the datasheets and read them.
