6534: Can't output data from a 16MB file of 8-bit data stored on HD using cont_pattern_output.vi

[jL637]

Hi. I used a modified version of the cont_pattern_input.vi to read and store my 16MB/s 8-bit data from the PCI 6534 to a file on my hard drive (one file is 16MB large). Now, I want to output that data from the file to the DAQ card and I am having problems when using the cont_pattern_output.vi. It is giving me Error 10843 and -10022. I don't understand what that error is trying to say and was playing around w/ it, and can't seem to get it to run through the entire program. If anyone can help, that would be great! Thanks!

Hello;

You should be able to do that without trouble. I wonder if there is something not quite write in your Software that is making that error to show.
I'm attaching an example Labview VI showing how you can accomplish the output pattern generation from a binary file.

You can start from that, and later, once you know that peace is working fine, you can try to integrate with your other peace of code that does the input part.

Hope this helps.
