sbRIO and datalogging

[MathBoda]

I would like to know if we can plan to make a datalogger with the single board which doesn't have any storage device implemented. 

The single-board RIO have 110 DIO connected to the FPGA  then we could connect almost any kind of storage device to make a data logger.

What we need is a way to deal with a Compact Flash or HD from the FPGA.

Is there any Labview tools to control these kind of device from the FPGA?

Is there any Xilink VHDL code that we could use to do the trick?

Any ideas ?

Regards,

Hi Mathieu,

The NI 9802 module (http://sine.ni.com/nips/cds/view/p/lang/en/nid/204328) offers easy expansion to the RIO platform for data logging. You can access this storage directly from the FPGA with an easy to use API.

As far as connecting the DIO lines directly to a data storage device, you would have to do quite a bit of electrical engineering to make sure the signals are compatible as well as a good deal of FPGA code to write your own driver for the FPGA to interface with a device with its DIO lines. Currently there is no intellectual property (IP) on our ipnet that does this out of the box.  You also might be able to get an alliance member www.ni.com/alliance to develop this for you.

I agree with Stephen that your best bet is to use an NI 9802 module. Its storage media is Secure Digital, which I don't see how would that be different than using Compact Flash (unless there is something about Compact Flash that I don't know about).
