When trying to perform Digital Input I get this issue:
"AttributeError: Task instance has no attribute 'ReadDigitalLinesU32'"

Code used:
from PyDAQmx import *

Declaration of variable passed by reference

digital_input = Task()

digital_input.ReadDigitalLinesU32(1,1,10.0,DAQmx_Val_GroupByChannel,data,None,None)

Try this:

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

"""

device is being reset. You might also get the error if the specified

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?

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:

""
from PyDAQmx import *
import numpy

#Declaration of variable passed by reference
digital_input = Task()
read = int32()
data = numpy.zeros((1000,), dtype=numpy.float64)

#DAQ Configuration Code
digital_input.CreateDIChan("Dev1/port0/line0","",DAQmx_Val_ChanPerLine)

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

#DAQmx Read Code
digital_input.ReadDigitalU32(1, 1, 10.0, DAQmx_Val_GroupByChannel, data,
byref(read), None)
print "Acquired %d points"%read.value
"""
"""
from PyDAQmx import *
import numpy

#Declaration of variable passed by reference
digital_output = Task()
write = int8()
data = numpy.zeros((4,), dtype = numpy.float64)

#DAQ Configuration Code
digital_output.CreateDOChan("Dev1/port1/line0:3","",DAQmx_Val_ChanForAllLines)

#DAQmx Start Code
digital_output.StartTask()

#DAQmx Write Code
digital_output.WriteDigitalLines(1,1,10.0,DAQmx_Val_GroupByChannel,data,None,None)

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?

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.
