Using sample clock with digital input

[sara25]

I'm trying to use a sample clock with a digital input, but I keep getting the error "Error -200077 occurred at Property Node DAQmx Timing"  with possible reasons being that the requested balue is not a supported value for this property..

Does anyone know how to fix this issue?

What DAQ device are you using? Look at the specs and see if the digital I/O is software timed. If it is, then you don't have s clock and must not use the DAQmx timing function and just write a single value at a time in a loop. This will result in s low rate with considerable jitter.

I am using a myDAQ...I just checked the specs and it says that it is software timed.

You might be able to get 1kHz. Anything faster will require different hardware.
