Subject: Re: [Emc-users] Dual boot for WIN-XP and LinuxCNC
My friend dropped off my new 7i92H card this evening. I've downloaded the zip
file and manual.
And I'm lost. I thought I understood that there was a LinuxCNC support file
that I could install or link to via the HAL to make things work. But I guess
not. Misunderstood that. I thought that it was possible to just configure the
7i92H as two parallel port cards.
I've tried the pncconf program and although the 7i92 card is listed it appears
to want other MESA cards none of which are simple BOBs. I really just want the
two ports to appear as parallel ports as stated in the manual. That means on
the next screen I should ideally have screens that are more like the PCI
parallel ports with the first 9 pins configurable for step/dir, pin 10 for
ESTOP in etc.
But on the two PORTx screens the pin numbers don't match the DB-25 pins.
I've attached my HAL file which is pretty simple at this point since I've not
even set up limit switches yet. Just ESTOP, Machine Enabled and ChargePump and
4 axis steppers.
Eventually there will be PWM and direction for the spindle. Shared Limit/Home
and Limit switches. But for now I just want to be able to press the jog
buttons and see step/dir out on an axis along of course with ESTOP and ENABLE
support.
I'm probably going to have to create the HAL from scratch. Or more like from
an almost but not quite prototype.
Can anyone help?
Thanks
John
Not sure why pncconf doesnt have a 7I92 config for a basic breakout, but in the
absence of one, you could create a 5i25 configuration for prob_rfx2 or G540x2
and then globally change "5i25" to "7i92" in the hal file and then steal the
driver load line from any 7i92 config (possibly removing any sserial related
tokens in the driver load line). That should be pretty close.
