VISA Write Error 1073807298 With mbed

[mejrissi.chiheb]

Hello everybody. I am using the mbed board for my new project.
I'm not familiar with the mbed so i have been trying to do some led blinking with labview.

I keep getting the 1073807298 error.

I have tried the VISA flush and the VISA set I/O as recommanded from previous posts but my problem was not resolved.

Can you please help me ?

Hi mejrissi.chiheb,

Have you seen our document which addresses this error?  I think it should provide more details on why you are seeing this behavior.

Warm Regards,

It appeared that i had misplaced the Set I/O block.

Thank you for your help

Hi Daniel, I got trouble when trying to interface an ARM MBED processor with Labview.

Measurement and automation explorer doesn't recognize the ARM as a "COM on USB" device (as suggested in the ARM web site to communicate with Labview), nor Windows does (arm mbed is always seen as USB device, with no kind of bindings to COM ports).  I'm running labview 8.6 and Windows Vista, M&A explorer ver 5.4.

So I configured my ARM MBED as USB RAW device and now it's recognized in measurement and automation explorer. When I try to write something to the ARM, I got the error message: "VISA:  (Hex 0xBFFF003E) Could not perform operation because of I/O error".  This kind of error occurs both in M&A explorer and in my VIs.

This kind of problems always occur when using non-NI hardware: I think it's some kind of protocol issue and I need to solve it once forever.

So, here's my question: where may I find  documents or procedures explaining how to handle raw devices with related configuration parameters?

Thank you very much in advance!
