Ok i used that example when referencing from the example on the homepage of the PyDAQmx website, but I came across this error of:

I have successfully used the Digital Output for National Instruments card PCI-622. I will try to help you, but this is hardware troubleshooting at this point, so I may ask you some dumb questions, cause I can't see what you've done/not done.

The error message you are getting suggests that maybe the card is being used by another process. I assume you aren't trying to read/write to the card simultaneously from your computer on the same lines? How is your digital signal getting on to the board? Are you reading the NI mapping correctly to get the correct lines/ports (this can be a bit of a nightmare, I find the NI documentation to be pretty lame)? Are you also running LabView or other software that may be trying to use these lines?

Thank you so much for your assistance and I have no problem providing you with this information. Yes you are correct that I am trying to read/write on the card with the same lines separately. I am not providing a digital signal at this time, I am just trying to get through the process of reading it just for now. I have read the NI mapping correctly aswell to verify that I am using the correct lines/ports. Labview, LabWindows CVI, and ANSI C are all not running. My code for both are as follows:

I have successfully used the Digital Output for National Instruments card PCI-622. I will try to help you, but this is hardware troubleshooting at this point, so I may ask you some dumb questions, cause I can't see what you've done/not done.

The error message you are getting suggests that maybe the card is being used by another process. I assume you aren't trying to read/write to the card simultaneously from your computer on the same lines? How is your digital signal getting on to the board? Are you reading the NI mapping correctly to get the correct lines/ports (this can be a bit of a nightmare, I find the NI documentation to be pretty lame)? Are you also running LabView or other software that may be trying to use these lines?

Ok i used that example when referencing from the example on the homepage of the PyDAQmx website, but I came across this error of:

DAQError: Requested operation could not be performed, because the specified digital lines are either reserved or the device is not present in NI-DAQmx.

It is possible that these lines are reserved by another task, the device is being used through the Traditional NI-DAQ interface, or the device is being reset. You might also get the error if the specified resource is currently in use by LabVIEW network variables bound to the DAQ Channel, or if the DAQ Channel is being used in any OPC Client software.

If you are using these lines with another task, wait for the task to complete. If you are using the device through the Traditional NI-DAQ interface, and you want to use it with NI-DAQmx, reset (initialize) the device using the Traditional NI-DAQ interface. If you are resetting the device, wait for the reset to finish. Device: Dev1

I looked manually at the DAQ to see if the lines and channels lined up and also ran a function that outputs the internal ports and lines, yet both agree saying that I am using the correct ports and lines.

Confusing NI documentation! Try this (it worked successfully on my setup):

from PyDAQmx import * import numpy

Declaration of variable passed by reference

digital_input = Task() read = int32() data = numpy.zeros(10, dtype=numpy.uint32)

DAQ Configuration Code

digital_input.CreateDIChan("Dev1/port1/line1","",DAQmx_Val_ChanForAllLines)

DAQmx Start Code

digital_input.StartTask() print "Acquiring samples continuously. Press Ctrl+C to interrupt\n"

DAQmx Read Code

digital_input.ReadDigitalU32(-1, 1, DAQmx_Val_GroupByChannel, data, 1000, byref(read), None) print "Acquired %d points"%read.value

Yes this does work! Thank you and would I also be able to send over my sample code for a setup I am trying to do with DO?

If you can't get it working. Take a look at OutputEvents in my code here, as this is a working example of Digital Output:

https://github.com/codedragon/pydaq/blob/master/pydaq.py

Not sure if your setup requires a strobe or not, but here is the code in action

https://github.com/codedragon/pydaq/blob/master/test_digital.py

Keep in mind that you are limited in the signal you send by how many ports you are using. I was using 16 lines, so could send pretty big numbers.

Thank you and I am still facing some problems. I have seen your work and it is great for the setup. I am however trying to create an active low reset that I have a default state, predefined duration, and goes back to a high state. I am still relatively new to this library and just want to see how the mechanics for this library are different from the pylibnidaqmx wrapper.
