Bug:

NI DAQCard cmd.stop_arg += 2048 needs to tested

unipolar support is not really working

Options
usenipfistart: Use as start source NI PFI channel
Trigger to analog input
You need to route the analog input start signal to pfi channel 0:
*Devices
Device1:
plugin : ComediNIPFI
device : /dev/comedi0
ident : pfi-1
channel: 0
routing: AI_START1
and tell the ComediAnalogOutput that it will be triggered by this signal:
*Analog Output Devices
Device1:
device : /dev/comedi0
ident : ao-1
usenipfistart: 0
delays : 0ms
Calibration:
For hardware calibrated boards (like NI E-Series boards) do
$ comedi_calibrate --reset --calibrate -f /dev/comedi0

For software calibrated boards (like NI M-Series boards) do

$ comedi_soft_calibrate -f /dev/comedi0

You may want to read the man page of comedi_calibrate.
