Hi - I'm having trouble getting DFSDM input to work with DMA - I'm unable to set the `DMAEN` bit in the DFSDM register.
One troubleshooting angle: What register pointer to you pass to the DMA's CPAR? I assume `DFSDM_ FLTxRDATAR` for regular (non-injected) conversions, but this is odd, since unlike most data registers you'd use with DMA, it has several fields; not just the data. Is this correct? Thank you.
