Driver Station Analog Port Sampling Rate

Hi all,

Does anyone know what is the maximum sampling rate for the analog ports on the driver station?

Cheers
-Tanner

Although the hardware supports a higher sampling rate, the analog ports on the 2009 Driver Station have an effective sampling rate of 50Hz.

Eh. That stinks. Drat.

Time to rethink things.

Thanks

Re: Driver Station Analog Port Sampling Rate

What are you looking to do? Maybe we can come up with an alternate solution.

I'm just looking to analyze the frequency/amplitude of a waveform (somewhere from 500hz to 1500hz). Exact use is a secret, but that's all we really are "researching" at this moment.

I was thinking a Arduino would be sufficient, but I'm no electrical guy nor have I ever played with micro-controllers (trust me - I soldered once with our electrical guy, it confirmed we both should stay in our current job positions).

Though the Aruino community say it might not be the best way to do it on that platform (see here).

That sounds like a perfect use for LabVIEW with the cRIO. You can sample far faster then you need with the analog input module we are provided. LabVIEW has a vast array of filters and display mechanisms that should make the analysis easy.

Our idea prevents such a device being mounted on the robot, and has to be on the user control end.

Though we do have two cRIO's, but I thinking have a whole 'nother cRIO just to analyze a frequency/amplitude is overkill for user control.
