I forgot to mention you also look in /dev to see how many nodes are made for the parallel port, and also look at what dmesg reports .

sudo cat /proc/ioports

Will return addresses

9710:9805 - NetMos Technology - PCI 1 port parallel adapter

Thank you very much for the tip!

If you aren't getting the address of the second parallel port come up adding the connector and resistors may not enable it.
Find the data sheet first and work out how to config the chip first before getting out the soldering iron.

You are right!

I tried to read the registers with the remaning adresses and it didn't work.  



I tried both Base/Extended ccd8/cce0 and cce0/cce8. Didn't work. They must be strapped, as you said.

 
 

 

I think i should do a summary of the Sunix PCI-E card as the info got scattered in pieces, so:
I had one, it works perfectly but:
In a Lenovo PC it show the warning when LinuxCNC starts, but it works fine
In another PC with Asus Prime Z270 board, it shows no warning and no ................................
IT JUST dawned on me:
It will show the warning on older kernels, it will not show on new-er kernels!!!
Lenovo has Mint 19.3, the Asus has Mint 21.3, the friend with the same model cards has LMDE 6
Ok just checked the original post and it is Debian 12 so most probably 6.1.nn kernel, should be the same as in LMDE 6, so there goes my joy, oh hell, back to more testing!

Offensive ?
Pointing out someone didn't want to lift a finger to sort the issue out even after they were given the solution ?
What really got my goat was the OP was the one with the issue, the OP had all the information available. If I was to raise an issue on GitHub, I would need to get my tower out storage, install a PCIe card, create a config and attempt to replicate the issue. Now how many cards would I need to try ?
So I'd put in a hour or two of my time for something the OP could of done in the time he made the post to say he had nothing more to say or make the report. And if it didn't get actioned straight away and new packages put up with their time frame the OP would not be satisfied.


Tho to tell the truth I wasn't surprised at considering the attitude.

As I stated before, a driver will load if there is a matching PCI ID for the hardware. I even gave the instruction that will show how to figure this out. Now if for some reason or another the people involved with producing or wholesaling the board decide for whatever reason to change the PCI ID and the driver doesn't know about it the driver won't load, it's not rocket science. Anyone who has anything to do with computer hardware knows that companies will change chipsets with models and give them new revision numbers, this was a thing to look for in the early days of wifi support in Linux, buy 2 models of the same card and one driver would work another wouldn't due to a change of chipset and PCI ID.

Hi all

I am using a DragonRise USB board set up  to drive various linuxcnc functions.
When I turned off the computer 6 months ago everything was working. Now I have turned it on, the inputs are working & the connected output pins are working but the software does not respond.

So....
input.0.abs-x-is-pos is the USb input (which lights up) connected to halui.axis.x.plus (which also lights up) .The machine is homed but the axis does not move.

I am using QTDragon on linuxcnc 2.9.3 on Debian. I have a second machine that I have not used for a while that is doing the same thing.
Is there some config type thing that I am missing here?

Attached are the relevant files

Thanks
Alex
