Pci card fo Linuxcnc

Good afternoon!  Tell me, is it possible to use different pci  i/o cards with Linuxcnc?  By default, only the settings for the parallel port and mesa cards are available in the settings, the question is whether other cards will be available in the settings after installing the card itself and drivers, for example, use a card on ch367

The Pncconfig wizard is a tool for building Linuxcnc configurations for Mesa cards. It does not support other hardware.

If the card you want to use isn't already supported by Linuxcnc you may be stuck having to write your own drivers for it. Unless you are very lucky (as I was) and can find a generous person to write one for you.

You will find all supported hardware on linuxcnc.org/docs/devel/html/ in section Hardware Drivers

This might be an alternative for you, which is still in development: forum.linuxcnc.org/27-driver-boards/4442...roller-board?start=0

Do you have the card?
if yes, insert it in the PC, boot a Live Linux session from USB and type: It does return a lot of text, but try to find the section with that cards info.
Also search for firmware for it, a lot of Chinese companies have firmware on the net to avoid lawsuits.

Today I order ch367 board 

Pci-1739u board 

And order pci-7432 board 

These cards are not very expensive, I can post their documentation and drivers here if you are interested.
I will receive these boards in about 50 days

As i said above, many of them have everything on the net, so:
www.wch.cn/products/CH367.html
At the very end there are Linux drivers, and everything else in between.

It's probably relatively easy to write a LinuxCNC driver for these boards if the documentation is adequate.

relatively speaking, I will need to write a driver to specify the ports of the card in Linuxcnc?

Yes. But it's not particularly difficult. 
Here is an example:
github.com/LinuxCNC/linuxcnc/blob/master.../drivers/pcl720.comp
It's for an ISA card, and the starting point is an ioaddr. But i chose it as it uses the .comp preprocessing language so it's relatively simple. 

For a PCI device it is usual to use DMA, so after a bit of setup you just need to put the data into variables that are part of a correctly-shaped C struct. 
I think that the memory mapping happens here, in the Motenc driver:  github.com/LinuxCNC/linuxcnc/blob/master...rs/hal_motenc.c#L309
