cRIO high speed data aquisition

[Eric_Lang]

Hello,

I have been using the scan engine approach to data aquisition on a cRIO for quite some time, logging analog inputs and strain gage readings at 200 - 333 Hz.  I now have test I would like to perform logging one channel from the 9237 Strain gage module at 10-30kHz.  I believe this throws me into the FPGA mode and am looking for help in direction or sample code to proceed.

Any help is greatly appreciated!

Thanks!

Hey Eric,

I would start with an example in the NI Example Finder.  You can find an example for the NI 9237 (FPGA mode) under Hardware Input and Output >> Compact RIO >> Module Specific >> Analog Input >> NI 9237 Getting Started.lvproj.

Here is another link that may help with using the NI 9237...

And here are some links that should help you get started with LabVIEW FPGA.

Hopefully these will help.  Good luck with your application!
