Re: [CAD_CAM_EDM_DRO] Encoder Based Progarmmable Limit Switch

Hi Roland,

Could you elaborate? How many outputs do you need? A PIC reading the
rotary encoder could compare several "setpoints" to the actual position,
and generate the appropriate level transitions on it's output pins.
What's your budget? The U.S. Digital encoder interface would also be a
good candidate to include in this design.

If you have digital I.C. design experience, a PIC and encoder interface
would be simple. Then you'd need a 2 or 4 line LCD, and a limited
keypad. No problem!

Anyone got some project time open? I'm swamped! (and on vacation ;>) )
