cRIO output large waveform

[Seky]

Hello,

I have cRIO with DA converter and I need to output digitalized data. The problem is, it is too large to send the whole waveform to the fpga at once. So I am thinking about synchronizing it with the host and periodicaly send only parts. Does anyone have a better solution or advice about this matter?

Thanks

Hi Seky,

               I agree that this is pretty much the only thing you can do - splitting it in smaller parts. Try using the DMA FIFOs for the data transfer.
