  1. Hey there, I got the problem that I need to "send" image data (format bmp, jpg, tif, ...) to the graphics adapter to the VGA-port for example with a Laptop. To the VGA-port a kind of small "beamer" is connected and I need to see only the file I send there and not the whole screen (Desktop). The Desktop remains visible on the laptop monitor. As the VGA-port is not treated like the other communication ports (RS232, GPIB, ethernet, usb..) I did not find any example and I suppose it wont be that easy to realize. I would appreciate a lot any hint on this. Thanks in advance Pepe
  2. Hi to all, finally I am using Unflatten from String in a While Loop. It works fine, just that HEX numbers above Axxx appear negativ :-\ Also with the Type Cast, they become negative, although I am using a 16bit word as type. EDIT: ok, now it works fine. I just had to change the type to "unsigned Word" Anyway, thanks a lot for your help
  3. Hi to all, I just spent some time searching the forum, but unfortunately I did not found a satisfying result... The communication to set up should be using the RS-232 interface. I am using VISA configure serial port -> write -> read -> close (LW 7.1) I got an auto-correlator which returns me 256 equidistant ACF-values as a row of 512 Byte with the following structure: 1.byte 00(hex)...FF(hex) 2. byte 00(hex)...C0(hex) . . . 511. byte 00(hex)...FF(hex) 512. byte 00(hex)...C0(hex) For that I am using the VISA read, which gives me the correct 512 bytes after sending the "G
  4. Ok, thanks a lot! It works fine Salu2 ;-) Pepe
  5. Hi to all. I got the problem, that I need to create a file with the arrays took received from an instrument. As the file for receiving the data from the instrument is quite big, I created a trial-vi to implement the write to file function lateron. I attach a screenshot of the result and the vi. My problem is that the data should be written to the file in format of a table. for e.g. [file name] testpath [data] -24,300000 0,000000 -24,300000 0,000000 -24,300000 0,000000 -24,300000 0,000000 -24,300000 0,000000 -24,300000 . . . and not in that way as it is indicated in the screen
  6. Hi again. Thank for your hint! Its working fine
  7. Hi Lynn, thanks for your hints I will try them right now. Regarding the Tutorial: I already passed through the tutorial but it was quite basic knowledge and what I need to do is a bit more complex. I will let you know, how its going... Thanks! Pepe
  8. Hi to all. I am completely a newbie on this field using LabView and so on and I hope you can give me some answers. Problem: I need to connect a Bit-error-Rate tester (in following BERT) via LabView with a computer to process the obatined BER. The problem is, the BERT does not give the BER directly, but the number of errors. For that I need to calculate the BER using time (used for the BER-measurement), bitrate and errors. The problem is, that the format of two values is a string and that these two values may vary with a new measurement. So I need to process them using Numeric operations
