Re: List question

The pic handles the encoders and had the PID filter. You need the PIC step
with the servo board and the rs serial board. You need to d/l the setup info
via a serial port to set the PID filter and the other parameters. Then you
can switch to the pic step and run your dos based parallel port programs
from there. I experimented with the PIC Servo and found that under serial
operations it was blazing fast. Under the pic step is was incredibly slow
where I was unable to get 250 RPMS out oif it. But I see that he is coming
out with a rate multiplier which should speed it up significantly.
I was going to design a servo system around the pic servo chip because it
was so low cost.
JRKerr even gave me the gerbers but the top layer gerber file was corrupted.
For some strange reason he would not send me another copy of the top layer
gerbers.
I also don't have the time to reverse design the top layer. Other wise I
could make a low cost servo system kit available .
