Yes. I have on my TODO list, the delivery of a beta version of the ni_pcimio driver into the xenomai trunk. This driver will match the features range provided by the legacy version (www.comedi.org). However, you should not use the comedi-rtdm-dev version, that was just a POC for the modified Comedi API. The trunk version will be available soon. Best regards.

In order to test comedi I was used to associate a driver to a device with the command # comedi_config <devicefilenae> <driver> When I try to execute this command the output is: "Xenomai: incompatible ABI revision level (neede=1, current = 2)". ... is it correct? What I have to do to test Comedi? What are the step I have to do in order to test the NI board I have available? ....I read the API documentation in http://www.xenomai.org/documentation/trunk/html/api/index.html however I am in lack of the correct logic to write a simple program to test my experimental set-up. Should you/someone help me posting a very simple "hello world" program to test the basic functionalities of xenomai-comedi? Thanks in advance!!!
