What does NI provide for custom camera file development?

Hi YR,

Thanks for the code you have sent and the time you spent.

But I would like to do this in the ICD file itself so that I can control it from NI-MAX.

Thanks,
Ramanan

The FF value you are looking at is a byte value. It needs to be output as a single character. In C, you would use %c to convert the number to a single character. This isn't available in LabVIEW, so I don't know if it will work in an ICD file. You could try it, though.

If it doesn't work, the only solution I see is sending the preconverted string from LabVIEW. I don't know how you would do it in an ICD file.

I tried %c in the camera file generator, and it didn't recognize it. I don't see any easy way to convert a number to a byte output.

Hello Ramanan,

When variables are used within a serial command, they are converted to ASCII first. For example, the integer 255 will be converted to ASCII "2" "5" "5" or hex 0x32 0x35 0x35. Even when the integer is formatted as hexadecimal 0xff, it still gets converted to ASCII "f" "f" (hex 0x66 0x66).

Currently, the only way to send hex values rather than ASCII values is to type "\xHH" where HH is the hex value to send. This method does not work with variables.

The alternative to sending the serial command from the camera file is to programmatically send it using the IMAQ Serial Read and Serial Write functions.

By the way...what camera are you using?

Thanks for your comments Mr.Jesse.

We are making our own CameraLink Cameras. One of our customers needed .icd file to configure our cameras with NI-MAX. We have developed some LabVIEW utilities to configure our cameras but our customer is very much in particular in getting the .icd file, because he already knows how to control the cameras with NI-MAX.

Thanks,
Ramanan

Is that FTP still available for download? I would like to develop some camera files for our cameras here and/or get them developed by NI engineers.
