Re: [CAD_CAM_EDM_DRO] Encoder to Step/Dir converter MPG

Hi Joe

there are quad to S/D or U/D conversion chips (about $3 ea) at
http://www.usdigital.com/products/ls7083-84/

but for a manual pulse generator you could just wire the A & B channels
right into a port and decode the states in software ,it still only uses two
input pins for the encoder

there was a flurry of posts on these about a month ago
(with $ticker $hock and all :-)
and another back in Nov-2000
and some of it wound up here
