This may be a little off course of the basic conversation but, I use a LOT of
quadrature optical encoders (incremental type) in motion control
applications.  So far I have been purchasing off the shelf, proprietary
motion controllers however, I would like to be able to use the PIC for the
controller and have it read the encoder which at most would be around 25 kHz
in frequency.  I am using the PicBasic Pro compiler and am just starting to
learn assembly code for the PIC. I think the compiled code will run fast
enough.  But, has anyone actually written code in the PicBasic language to
read a quadrature encoder reliably, and if so, could you post it on the list
for me to take a look.

Also, I would like to be able to use the PIC as a PLC.  Is it possible to do
both in a single PIC or would one need to use separate PICs for each
application.

Any help will be greatly appreciated.  I am sure you can tell I am fairly new
to the PIC scene.
