Hey Alexis, Thanks a lot for your quick response.
>> Is rt_comedi_test an application you developed ? Yes, it is my little test application, which is kept simple (open, read, close). >> I think you should follow the common comedi way: >> 1) Check you have the suitable driver loaded: xenomai:/proc/xenomai/rtdm> cat /proc/comedi/drivers -- Comedi drivers -- | idx | driver name | 00 | ni_pcimio >> 2) Check the comedi RTDM devices available: xenomai:/proc/xenomai/rtdm> cat /proc/xenomai/rtdm/named_devices Hash Name Driver /proc A1 comedi0 rtdm_comedi comedi0 A2 comedi1 rtdm_comedi comedi1 A3 comedi2 rtdm_comedi comedi2 A4 comedi3 rtdm_comedi comedi3 A5 comedi4 rtdm_comedi comedi4 A6 comedi5 rtdm_comedi comedi5 A7 comedi6 rtdm_comedi comedi6 A8 comedi7 rtdm_comedi comedi7 A9 comedi8 rtdm_comedi comedi8 AA comedi9 rtdm_comedi comedi9 >> 3) You have to attach the driver to the rtdm device you want to use >> with comedi_config (a tool available in Xenomai). >> #comedi_config comedi0 comedi_pcimio >> That command will assign comedi_pcimio driver to comedi0 r...@xenomai:/usr/xenomai/sbin# ./comedi_config comedi0 comedi_pcimio comedi_config: comedi_snd_attach failed ret=-22 r...@xenomai:/usr/xenomai/sbin# ./comedi_config comedi0 ni_pcimio comedi_config: comedi_snd_attach failed ret=-5 >> 4) Eventually, you can test the acquistion is working with some test tool of ours :cmd_read >> # /usr/local/bin/cmd_read -v I don't find this test tool.

Is there a difference between HEAD and ABE that does matter to me ? Apparently, I don't have comedi_pcimio. How do I build it and where can I find it ? It seems not to be in xenomai 2.5-rc3. I will downlaod xenomai-abe.git and see what I get. >> the driver name is comedi_pcimio instead of ni_pcimio. So you should type comedi_config comedi0 comedi_pcimio. So, the comedi_pcimio is the driver I'll need ? Is the no National Instrument specific driver ?? (ni_pcimio) ??
