Re: [ts-7000] Precision Timing

[Grant Stockly <>]

I've had luck with the PIC servo from JRKerr.  You'll need to
provide your own amp like the LMD18200 or just buy their completed
board.

I'm about to experiment with the LM628 or 9, the one with the quadrateure
feedback inputs just so I'm not tied to someone elses
firmware.   Very low part count interface/driver circuit
too.  You can also buy something called the Andi-Servo.  Its a
PC104 card with 2 LM62x chips on it and 3A 50V drivers.  We've used
those in the past, they work well.

Hi ,

   The Linux kernel bundled with this board could not provide precise
timing for servo motor. If you just want to drive servo motor, I would
suggest you got a servo motor controller from other sources:
