NI USB 8451 with Sigma Delta ADC interface

[00390114330404]

Hello everybody,

I really apreciate it if you could let me know how can I record online SPI stream from ADS1278 Sigma Delta ADC without any delay.

Is it possible to use NI USB 8451 card to receive non-interruptable SPI data stream ?

Thanks a lot,

Should be possible, as long as your data rate is within the spec of the 8451.   Can't remember it offhand.  What's the clock rate on your data?

Thanks a lot,

The clock is 10 MHz.

I had a worry if the streaming would be continous on the software side on the computer.

Do you think it is feasible ?

Can I use one-way data transmission (no feedback)?

Thanks a lot,

10 MHz is a bit high.  I don't think I ever took the 8451 above 500 KHz -- so I don't know for sure.
