Can I use simultaneously the analog input and output of my NI MyDAQ card in session-based?

Asked by Jose Luis Vargas L on 24 Oct 2012
I'm trying to make a realtime app with my NI MyDAQ, but I have problems to simultaneously use the analog input and output. I just follow the tutorial of Matlab ( but when I start the adquisition with s.startForeground(); I get the error:
NI Error -200077:
Requested value is not a supported value for this property. The property value may be
invalid because it conflicts with another property.
Property: DAQmx_StartTrig_Type
Requested Value: DAQmx_Val_DigEdge
You Can Select: DAQmx_Val_None
Task Name: _unnamedTask<164>
Status Code: -200077
How can I change this DAQmx_StartTrig_Type to None?
