Other Parts Discussed in Thread: CC3200

Hi,

I have a question about the CC3200 using the ADC with the DMA. Can the ADC work with the DMA?

While sampling in the background, I’d like to take data from the on-chip RAM and dump it to external memory without interrupting sampling.

With the DMA API, I did not see any examples with the ADC.

Thanks,

David

Hi Kumar:

I have similar question.

When collecting ADC sampling data, can I write data into Flash memory thru DMA?

Or can I write ADC data into SD memory thru DMA?

Thanks

David,
Would you be able to send a similar sample to me? I am trying to write ADC samples to a file.

Thanks,
