Hi gregoryj,
thx for the advices,
the 5v part is when i was using analog input
i've changed to digital input now

Hi Varaprasath
when i'm using the DAQ Digital i/o sometimes it detects logic1 even when i did not press the button but it doesn't happen when i'm using DAQassistant,
is that a problem with my hardware or something else?
edit: i disconnected my hardware from myDAQ but it still shows logic1 at times
Try to Pulldown or Pullup in your digital input Pin using a resistor. which control yours floating state.
Can I Use a Pull-down Resistor to Set the Default State of the Digital Lines on my NI DAQ Device? (try this link)
If internal Pulldown or Pullup is hard try to put an external Pulldown or Pullup .
do some analysis on resisitor value (4.7k), in your case MCU is DAQ.

1) Before using DAQmx driver, use NI-MAX to check how the input responds to your button
2) Depends on this u can guess hardware issue or software issue.

i've been trying to solve this issue for some time, tried using the external method but doesnt seems to work.(i also looked for alternative ways)
is there a way to use the DAQassistant instead? when i right click > properties > run it seems to work just fine (only logic1 when pressed)

Hi karthickkece,
how do i get to the NI-MAX ? is it a vi. or a function in LabVIEW?
can't seems to find anything on this

Oh found it thanks, Dennis.
@ karthickkece
tried on NI-MAX doesnt seems to have any problem
