NI PCI-6221 M-Series AI

Hi everyone!

 

I am trying to get a NI PCI-6221 to run with a 2.6.15.4 kernel, comedi
0.7.73, comedilib 0.7.22 and rtai 3.3 and the automatic code generation from
Scilab/Scicos. I can write out data at the AO port, but when I try to read
from the AI port the input seems somehow saturated and I get no useful
signal. I compiled comedi_soft_calibrate but when I run it, I get a
Segmentation fault.

 

Has anyone experience with this problem and some help with this problem?

 

Thanks

Benjamin
