read digital line input

[Andylwk]

Hi all,

I have a stream of digital data coming into 1 line in USB-6501. I have configured 1 digital line input using the DAQ express. How do I able to read this stream of data in an array or table with the time interval?

Any help is appreciated. Thnaks.

You can configure your DAQ Assistan to read N samples, where N is the amount of bits that you want to read, and save them into an array of booleans.

Regards.

I have configure the DAQ assistant to N samples with the required number of samples and rate. I save them to a boolean array but i have an error. It say the source is 1-D array of digital waveform and the sink is 1-D array of boolean.

It's irrelevant since you cannot set the 6501 to read N samples at a specific rate. Your only option is to use On Demand timing. Surely your DAQ Assistant is giving you an error.
