how to read from a text file

[lightmiddle]

I have a long chain of binary numbers in a text file as attached.

I wanna read each column out to an array  and for each column I need convert every 32bit into a U32 number.

I wrote a VI but the vi can only read the first column and I also think there might be a better way to do the converting , any good idea?

Thanks a lot.

Could you attach a real sample text file?

sorry

here is the real txt file. I need the first 4 columns.

Thanks .

If I understand the problem correctly, this should be one solution.  See Attached LV7.1.1 example

Thanks a lot .

by the way how do you convert the Hex to Dec ?

[PJS]

With the finger pointing tool, click on the x (Radix) and select decimal.  No extra conversion need be accomplished.

Yesterday I made a quick draft, waiting for the data file. It is slightly different to Pauls but seems to give the same result. 🙂

You pick 😉

(btw: It might be much more efficient to read the file as string and parse it directly as U8. There is no need to allocate  4 bytes for each bit in the SGL array.)

Here's a quick modification of my example that only reads the first four numbers on each line and converts them directly to a boolean array. 😄
