How can I change DIO frequency?

[purekth]

I am using Labview to control DAQ board (USB 6259).

With default setting, I can see that the digital output signals are running at 50Hz.

In manual, it is said that USB 6259 can generate digital signal up to 1MHz.

I don't know how to control the digital signal frequency.

Thanks,

Tony

Hello Tony,

The only way to generate a digital signal on a MultifunctionDAQ device is to utilize either an external clock or to use one of the onboard counters to generate the needed clock. An example of doing this can be found at Communities: M-Series Continuous Digital Output. This example can be easily built on to generate any pattern you need to out of your digital lines.
