Hi,
I am using comedi-0.7.67 with the multiq3 driver modified to avoid the
"Fix incorrect return value of AI insn function" (see most recent cvs
mod.)
The analogue input (Quanser Consulting MultiQ-3) seems to return the
correct voltage V when V is negative. But when V is positive, it
returns V-5 volts. This seems to happen on all channels.
Any help much appreciated,
Thanks,
Peter.
