output a digital signal with 6533 from a txt file

Postby rcatxi on 25 Sep 2014, 19:35

Hello,
I start with labview and I am using the PCI-DIO-32HS (6533) to output a digital signal.
I have to generate a digital signal with the 0-1 values from a txt file (I have attached a typical txt file). This signal must have a variable frequency (typ. 1.2Mhz) that the user can change. The level of the 1 (the amplitude: Vcc) should be variable too (1v<Vcc<7v).

1: it is possible to choose different amplitudes for a digital output in the NI 6533?
2: Should I use the DAQmx - Timing VI?, and how?

3: Should I generate a digital waveform direct with the String-table to Digital data (VI) or should I copy the one and zero values to an array and then output these values with the help from de DAQmx timing?, and how?

4: I´m trying with the attached VI but the -200077 error appears and maybe I´m doing a lot of wrong thinks. What can I do to improve that or should I do in another way?

I will really thank for the help and advice you can give to me.
