devantech USB-I2C converter and labview

[Marc]

Hi,
I bought a USB-I2C converter from Devantech. The driver sw installs a
virtual COM port for the USB communication.
With the demo program it works but I can not manage to get it to work with
the Labview 6.1 serial vi's.
Is there anybody who has experience with this?

Regards,
Marc

Can you get it to work with hyperterm?  My first thought is that one of your settings is wrong.  From my own experience, I usually figure that out with hyperterm.

6.1 had serial and VISA VIs I believe... I bet you should try using
the VISA functions to communicate with the device.

Hi,
thank you for your answer to my question!
Yes, labview 6.1 has VISA but it doesn't work either. Do you have experience
with the USB-I2C converter from Devantech?

Well there should be some documentation with the device that describes the commands you can send to it, to do the things it should do. We can not help you with that as we do not have that device.

Once you get those commands you will probably want to use HyperTerminal to try and play with it a little. You can also go into Measurement & Automation Explorer and selecting your port you can use the Interactive Control Panel to do similar. If you have gotten some communication in that way and have an understanding of how the device works you can start coding in LabVIEW.

Basically until you can get some basic communication with the device from HyperTerminal, trying to make it work in LabVIEW is wasted time.
