<font size="+1"><tt>Hi CLUEbies,<br>
<br>
I'm doing a bit of research and I need to find an OEM data acquisition
module which I can use from a Linux program. That is, it has to have
Linux libraries. Most of what I find on the 'net is for Windows and
they have Labview libraries with only Microsoft Windows support. I
found one company <a href="http://mccdaq.com" target="_blank">mccdaq.com</a> which has a USB OEM module (the USB-7000
series supports Linux) but those have not enough digital I/Os or else
low resolution (12-bit) analog input. Their more powerful boards are
Windows only.<br>
<br>
Any ideas from the CLUE audience about where to look? This is for an
embedded industrial control type application that also requires high
resolution (very high accuracy & precision) sampling of some analog
inputs. We need 16-bit resolution at least. It doesn't have to be
fast, 4Hz is what we have now. We need at least 16 digital I/O and 8
16-bit analog input. Isolation is good too.<br>
<br>
It'd be nice to get a prepackaged board with software but I've thought
about trying to roll my own with Arduino. The only A/D example I see
for the Arduino is 12-bit resolution. I guess I could put them back to
back as differential inputs and get 24-bit resolution, but either way
that is a fair bit of hardware complexity and time/effort that I'd
rather just buy.<br>
<br>
Thanks,<br>
Jim<br>
