AW: PCI I/O cards

["Markus Meyer" <meyer-at-mesw.de>]

Dear Kurtis,

I'm also going to use a Sealevel card, but have not been able to do any
programming yet.

The problem that the Sealevel drivers are not loaded is likely to be a
configuration problem with the Sealevel script and I don't think that is has
to do with EMC.

The relevant code for the I/O can be found in emc/src/emcio. If you want to
read the outputs from the sealevel card rather than from the parallel port
you have to write a own "driver", that overrides the "extDioRead",
"extDioWrite", ... functions. Changing the makefile will also be necessary.

If I really use the Sealevel card, I will of course contribute the changes
to the EMC source tree, but I'm afraid that this will not happen before
spring 2002 or even later.


Best regards,


Markus

Calling Linux programmers,

My EMC application requires more I/O than is presently configured to the
parallel port with the Bridgeport "plc".
I am hoping to move the parallel port stuff (lube,spindle,coolant,estop) to
a Sealevel PCI Bus 48 TTL Digital I/O Interface as well as incorporate the
remaining I/O.
(8 tool limit switches, remote pendant functions, x and y axis brakes)
The software that came with the Sealevel card has two steps:
step 1.  =  install drivers.  This worked and prompted installation
complete.
step 2.  =  load drivers.  This uses the mknod command to create device
special files.  Running the load drivers resulted in :  mknod: wrong number
of arguments
The manufacturer of the card (Sealevel) assures me that the program works on
Linux.
How can I read and write to this PCI card the way I do with the Servo to Go
card.

The next step will be to include STG analog inputs of spindle speed and
spindle load on the Tkemex Gui.  Ray says the GUI stuff is the easy part.
