The ax driver is intended for a 48 IO ISA card but I'd hook up a switch to one of the inputs and see if it changes in the HAL. If it does then we can look into that iioo config stuff and see if we can expand. I'd try the switch on several of the inputs. One for each set of 8 inputs. You need pull up or pull down resistors depending on the nature of your board. In my early experiments with this stuff I was able to lock up the PC while doing some of this stuff. Don't be surprised if your's does.

There is an issue with the pci_8255 driver at the moment. If any of the pins are set to inputs - it will hardlock the computer after a certain amount of time. (not really sure as I have not looked at it for a few weeks iirc it seems to be dependent on how many times the input gets switched.)

Dave You do not use the National Instruments driver. EMC2 uses HAL (Hardware Abstraction Layer) to access hardware. You need a HAL driver for the board. EMC2 includes quite a few HAL drivers, there have been two mentioned in this thread that might work for that board, or that might be suitable as the start of a driver for that board.

Re: [Emc-users] 8255 driver
There are two drivers, one for the AX5214 and one for the Futurlec PCI8255 card. They are called hal_ax5214h and pci_8255, respectively. The pci_8255 driver has been included with EMC2 since 2.2.0, the ax5214 driver has been there since before the 2.0.0 release. For either card, you have to supply the base address to the driver, along with a string describing the directions you want the pins to be. AFAIK, the pci_8255 card has a single chip with the PCI bridge and the equivalent of 3 8255 chips in it. The PCI card should be seen and initialized by the BIOS or Linux. Usually there's a BIOS setting for plug-n-play OS or similar. Setting this to no or off makes the BIOS do more initialization than it would otherwise do, so even if Linux doesn't know what the card is, it should at least have its memory and IO regions set up correctly. The Linux kernel does this pretty well anyway - it'll just list unknown cards as unknown vendor / unknown device or similar, but should still set up address regions for those cards. (I know it does this with the Mesa cards, for example) There are only minor differences between the two drivers, but one or the other should work with just about any 8255-based card (or register compatible ones) with minor changes. - Steve Gene Heskett wrote: On Wednesday 30 April 2008, Thomas J Powderly wrote: Gene, pci_8255 is in my cvs emc2 run-in-place installation pci_8255.c pci_8255.o and i think the hal_ax5214h.c driver in all emc2 installs is really an 8255 (the src doesnt say that, so may be wrong) From the looks of the link I found on google, it is a ttl ssi version of a pair of 8255's, for only 48 bits of I/O. If that driver can be expanded to handle 3 'channels' or 'groups', and can have its I/O addressing made compatible with this card, whose I/O addressing IIRC wastes addressing space by not making all 3 chips contiguous, then it might work just fine. Those are the gotcha's I recall from when I was playing with it before giving up and throwing more money at a xylotex kit with 3 motors. tomp Great Thomas. Is this code you did, or were you able to make the code that came on the cd's with the cards actually build on linux? in On Tue, 2008-04-29 at 22:56 -0400, Gene Heskett wrote: On Tuesday 29 April 2008, Andrew Ayre wrote: Wow - 8255s - I didn't know those were still used for commercial products.

I wasn't aware that it could be turned off and still boot. I'll have to check that on my box next week, thanks. The Linux kernel does this pretty well anyway - it'll just list unknown cards as unknown vendor / unknown device or similar, but should still set up address regions for those cards. (I know it does this with the Mesa cards, for example) At the time, booting bdi-4.3something, there was zero mention of any such devices in the dmesg or lspci outputs. Completely invisible until you found its magic address and tickled it. The cards I had, were a slightly earlier version that had the 82c55 chips mounted vertically, with the 34 pin headers also vertical, and all the cables could be simply taken directly out a missing card cover opening on the back. Now the 34 pin headers are along the top edge of the card must be folded to point them out of the back of the box. Much messier IMO. If you poke around on that site, there is a pix of the cards I had, but the link to the full page then has the newer card in its pix. There are only minor differences between the two drivers, but one or the other should work with just about any 8255-based card (or register compatible ones) with minor changes. - Steve Thanks Steve, here I had thought this card had fallen off the table and been swept up with the garbage. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
