Ok, what is a NI driver? > However, if you want to add a new driver which comes from the original > Comedi set, there will be little work to do as the API has changed a little > bit. oops ... > Which driver is it ? the jr3_pci. It's a pci card, with a dsp to read the signal from a force sensor. http://www.comedi.org/cgi-bin/viewcvs.cgi/comedi/comedi/drivers/jr3_pci.c?rev=1.5&view=log > You may have noticed that I am still developing Comedi4RTDM.

It's a lot of work ..... but there's one think that I don't understand. Are you modifying the comedi sources? Because is yes, the idea is to have not a fork of comedi, than the efforts in the comedi team then will be used by the xenomai team. > Because of many issues, it's been while since I committed on the Comedi > branch (too many bugs/instabilities, lack of time, etc.).

I have no idea about the comedi drivers structure, neither the xenomai. I can be a tester, sure. I have just compiled, making a debian package, installed and sent the test. If I can have this driver, I can use xenomai if not, I have to return to rtai .... and I think that it's very interesting in my case use xenomai and not rtai.
