7I90HD via EPP parallel port was created by phillc54

I have a 7I90HD and am trying to connect it to a EPP parallel port.

phill@jessie-64:~$ lspci -vv
shows the following:

phill@jessie-64:~$ halrun
halcmd: loadrt hostmot2
Note: Using POSIX realtime
hm2: loading Mesa HostMot2 driver version 0.15
halcmd:

I try:
halcmd: loadrt hm2_7i90 ioaddr=0xdc00 config="num_encoders=-1 num_stepgens=-1"
which gives:

I then try:
halcmd: loadrt hm2_7i90 ioaddr=0xd880 config="num_encoders=-1 num_stepgens=-1"
which gives:

These show slightly different errors from rtapi_app_main but both fail.

Can anyone shed any light on this for me.

Cheers, Phill.

AFAIK most if not all MOSCHIP parallel port chips have a broken EPP implementation
so will work fine for normal LinuxCNC SPP use but fail if you try to connect to a EPP
peripheral. Best choice for using a 7I90 in parallel port mode is a on board parallel port
Next choice would be a known good PCI/PCIE parallel port card, for example Oxsemi 952 based cards

I got hold of a card with a Oxford PCIe952 chip and still cannot connect to the 7i90.

I have tried both addresses.

I noticed that the first line of lspci -vv mentions [ECP]

Does this mean that I somehow need to switch the card to EPP mode?

It looks like the I/O high address is not correct (I would expect it to chose base +0x400 automatically)
The I/O high address is needed to change the mode

If I specify ioaddr_hi=0xe000 it makes no difference to the result, it still looks at 0xd880...

I also tried ioaddr_hi=0 as per the man page and got the same result.

It appears to work if I add epp_wide=0 to the loadrt line (why did I not try that before???).

It loads then lists the pins and show pin and show param seem to give the correct output.

I have only done this remotely so when I get home this evening I will connect some I/O up and test it out.

Another roadblock...

loading the card gives what appears to me to be success:

Both the leds stay off. :-(

I do getp hm2_7i90.0.led.CR02 and it returns TRUE.

What am I doing wrong???

Those commands will do no actual communication with the 7I90 card as
you have not setup a thread and addf-ed the 7I90 read and write functions
to that thread

At this point its probably better to have an actual hal file

You need to setup and start the realtime theads for anything to happen on the board.

Code:

loadrt threads
addf hm2_7i90.0.read   thread1
addf hm2_7i90.0.write   thread1
start

Is how you do that in a halrun command line session.
