6025e daqmx analog out then input

[James_R]

I have a 6025E card and I am trying to output a triangle wave on ao0 and read it back on ai1.  it used to work until i added three more analog inputs then i get buffer errors.  I tried changing the analog out to interrupts but it says that property is invalid.  i went into MAX and output a sine wave on ao0 and when i read it back into ai1 in the test panels i a sine wave with a bunch of steps.  Is something wrong with my card? i tried to reset it with no luck.  I even tried the shipping examples and get property invalid on the interrupt and it doesn't like the sample clock?

any suggestions ?

Hey James,

Is there a particular reason you are want use interupts? DMAs are generally much faster. If you are getting buffer errors, try increasing the size of the buffer using the DAQmx Configure Output Buffer.

Let me know if that works for you.
