Hi,
Can anyone help me with DIO Read operation using PCI-6254 (DAQmx)??
here'e the breakdown of the issue i'm having:
i'm doing a DIO Read using DAQmx drivers, and am using "one channel for each line" on the Port 0.
i'm using another line for DIO Write at the same time...infact the DIO write sends the bit pattern
and inturn triggers an external device, and am trying to capture the response of ext. device on
other line thro' DIO READ...
now, i do see the bit pattern on the Oscope, but am not reading the bit pattern using DAQmx Read?
(i'm reading all ZEROS)
Currently, i'm not using DAQmx Trigger? i tried using it, but was getting an error...
i guess i need to trigger the read when the line goes high/low (for ex)
can anyone help me with this?
