can I read & write stdf files from labview

[Michael.Johnson]

I need to be able to import & (potentially) export files in STDF (Standard Test Data Format- binary file format used with Teradyne Test Equipment, etc) format from within labview... has anybody done anything like this before? Has anybody come across anything which might be of use to me here?

Thanks,

M.J.

Hi MJ,

You can open and read a binary file in LV. I don't think the format matters, except when you want to manipulate the data within the vi. For that, you may need to TypeCast to the appropriate type and manipulate it as you wish.

You open the file and read it (and close it ;o). You'll get a string, typically of ASCII characters for a binary file. Then TypeCast it to the appropriate type and parse it according to the standard format. This output will become useful for you to manipulate it. To "export" it, you'll have to convert it to a Byte Array before writing it to the file.

In LV7, there are vi's to open binary files under File IO, Binary File VIs. However, you can also open them using the regular file handling vi's. The output of the binary
file vi's can be a 1-D or 2-D binary array.
