Pamux ac28 port configuration on turbocnc?
I am modifying my bridgeport milling machine again. I am running
a copy of turbocnc.
Wanting to install a Opto-22 pamux ac28 parallel address card. It
has a configurable address at 100h 140h 180h or 280h.... It has 16
bits with the second 8 bit word offset by address, usually at the next
8 bit level. You can address 512 points like this. I have a 16 bit
card for limit I/O and motor control.
Looking at the code, I think changing the parallel port address
would almost work. Using the assembly tranfer to the port will work
fine, but also changing the pins to accept input/output on all points too.
I hate to reinvent the wheel, has anyone else made this conversion
on the code?
