Hi all,
I recently acquired a HSDIO PCI 6541, but I'm having some trouble with streaming data to the disk.
I downloaded and can use the basic VI from http://zone.ni.com/devzone/cda/epd/p/id/5271 (NI-HSDIO Stream to Disk (Acquisition) Using Win32 File IO).
My question is: Can I use edge triggering with the above VI (ftp://ftp.ni.com/pub/devzone/epd/ni-hsdioacquisition-basic.zip)?

Update: It is possible. I had the Advance Edge Trigger set incorretly. Working now.
Edit: I also upgraded the HSDIO drivers to 1.6 from 1.5.4.

Im trying to do the same thing with a PCI 6551. Trying to generate from disk and acquire to disk at the same time, and i have it working with a SW trigger. That leaves me to manually line up the generated data to the acquired data.
What id really like to get working is a HW trigger. ive tried implementing the old gen PFI1 ->acq PFI2 using the start trigger/digital edge, but it just wont trigger. I have verified the PFI1 edge is actually being sent.
Is this simultaneous streaming gen-acq possible with a HW trigger?
Please help if you can
thanks!
