Module stm32_hal2::dfsdm

Digital filter for sigma delta modulators (DFSDM) support. Seem H742 RM, chapter 30.

Structs

Dfsdm

Represents the Digital filter for sigma delta modulators (DFSDM) peripheral, for interfacing with external Σ∆ modulators.

DfsdmConfig

Configuration for the DFSDM peripheral. All operations in the DFSDM peripheral are in signed format (filtering, integration, offset correction, right bit shift).

Enums

Continuous

Set conversions to regular, continous, or contiuous fast mode. Sets FLTxCR1 register, RCONT and FAST fields.

DfsdmChannel

DfsdmClockSrc

Toggle clock clourse between system and audio clocks. Sets CH0CFGR1 register, CKOUTSRC field.

DfsdmInterrupt

The type of DFSDM interrupt to configure. Reference Section 30.5 of the H742 RM. Enabled in FLTxCR2. register. Monitor in FLTxISR register. Cleared by writing to the FLTxICR register, for most.

Filter

FilterOrder

Sinc filter order. Sets FLTxFCR register, FORD field.

SpiClock

SPI clock select for a given channel.
