The Hall Effect sensor wiring?

Discussions state that you need to plug A phase into pwm6 and B into pwm 1

how do you wire one sensor to the 2 pwms?

First, I assume you mean dig io, not pwm!

Second, in using Hall sensors, you actually need two placed closely together with a slight offset. You can reference the actual application note at http://www.allegromicro.com/techpub2...ion_detection/

The first sensor gives you phaseA; the second, phaseB

Ours give execllent and reproducible results. The trick is mounting them. We machines out pieces of delrin to hold them in the desired configuration. Since there are magnets in them, they want to push apart!
