Hello everyone,
I am currently working on a project with myDAQ and labVIEW. I am trying to interface with a sensor that uses I2C interfacing protocol via the myDAQ. I believe labVIEW has a library for I2C interfacing, but I was wondering is the myDAQ will support I2C interfacing.
Please let me know if you have any experience with this and what you recommend.
Also, let me know if there are any tutorials, examples etc for how to do I2C interfacing with the myDAQ and labVIEW.
Thanks!
Best Regards,
Yzhi

The basic idea is that I2C requires the hardware to be able to do “Per cycle tri state”. The myDAQ does not support that feature. In fact, all digital interaction is software timed, according to the manual.
I hope this answers your question. Let us know if you need more help. Have a nice day.
