Can I READ a digital OUTPUT port?

[SallyA]

Hello,

Is it possible to "READ" the output states of a digital port?

I have a 6229 board and using nidaqmx and programming in c.

Thanks

Sally,

That shouldn't be a problem. Just put a DAQmxRead right after your write command. Basically even though the line is configured as output, you can still make reads on the task. I have done this a number of times in LabVIEW, and doing it in C shouldn't be any different. Hope that helps, let us know if you have any other quetions concerning this.
