Hello everyone,
I want to have an I2C module plus Analog/Digital Modul, connected to PC,
I found the USB famous USB-8451, and other A/D modules
But I was wondering if there is a better solution, where I can put both for example in one place,
I found the CompactDAQ, but I didn't find any I2C module can be connected to it,
Is there is a similiar cheap solution (not PXI RT for example)
There is no RealTime restrictions, only simple I2C and analog read/write operations with labview
Thank you in advance,

Hi
A cheap but slower and less resolution could be an arduino chip.
You have to program the arduino but that is not very difficult depending on your knowledge.
It has analog in on board and a kind of analog out via pwm.
The digital IO can be used for I2C. libs are available.

Thanks Albert, If you mean "Linx", i think the problem its not meant for commercial use, only for personal, and i intend to use it commercially,
Actually it would be perfect solution for me, using a pi or arduino, but I cant use labview runtime engine with them commercially 😞

thanks 🙂
But this has I2C library or you implement it all by yoursef,
is there is a manual guide, or tutorial on how it works, or

Update to any wondering ppl:
I think Linx never meant to really work, it was only for Advertisement but not practical solution,
Its extremely limited in so many ways, with no professional support, and the forum not real,,
May be its good for a hobby but definitely not for companies, as I believe this what NI wanted...
However, The fastest and easiest solution I found, just a raspberry/Orange pi with couple of threads having some I2C libraries,
And a TCP/IP Client/Labview sending/receiving commands, as I2C not that real-time demanding anyway,
a pi will be more than enough 🙂
Which has also some Analog I/O's

Maybe you right,
But for me, it has no support, its limited to LV2014, and only works with special os on the older pi,
its not meant for continual, the forum of linx almost deserted since long time, no one answering anything...
S, its not practical at all for continual projects ...
