Daten aus datei lesen und getriggert auf dig. Port schreiben

Erst mal Dank an monoceros84...


NI hat mir mitlerweilen folgende Antwort zukommen lassen:

The attached program opens a file and then writes the data into the DAQmx buffer using the DAQmx write. The reason they are seeing an error is not specific to the PCIe-6537, but rather a general programming problem. They are running out of memory.

In order to store data in memory, you need contiguous memory. By reading a 1 GB file, you are using most of this space. When you try to write this data into the DAQmx buffer, there is no longer 1 GB of free contiguous memory and you are getting an error. This error is not very descriptive.

To fix the problem, the customer has several options:

1) Only read smaller files.
2) Read the file into memory in chunks and write these chunks into the DAQmx buffer.
3) If the files are not much bigger than the size that works, you can use LabVIEW 8.5 and use the /3GB switch which will increase the chances of getting contiguous memory.
