Modules

config

Config value types used across the driver: filter parameters, data packing and shift modes, clock/output sources, and trigger/edge configuration.

detector

Instance-level and filter-level detectors: the analog watchdog, extremes, short-circuit and clock-absence detectors.

dma

DMA support: the ring-buffered regular-conversion filter that reads converted samples via DMA.

filter

Filter and its interrupt handling: filter configuration, the filter driver type, the interrupt handler, and per-filter interrupt/event state.

splits

Split-build traits: the interface between configure_pins’ closure tuple and the shape-dependent split structs. The split structs, selectors and ChannelCfgTuple impls are generated by build.rs (see src/dfsdm/codegen.rs) and glob-re-exported from crate::_generated::dfsdm.

transceiver

Transceiver driver, its pin reference-counting storage, single-use pin selectors, and the pin-trait associations.

types

Type-system: sealed and capability markers, channel markers, pin-presence (PinSet) and channel-config tokens, indexed channel types and trigger types.

Structs

ChannelSelectors2

The pin selectors handed to the crate::dfsdm::Dfsdm::configure_pins closure. Declare each transceiver’s pins with crate::dfsdm::Sel::datin, crate::dfsdm::Sel::datin_ckin or crate::dfsdm::Sel::none.

ChannelSelectors4

The pin selectors handed to the crate::dfsdm::Dfsdm::configure_pins closure. Declare each transceiver’s pins with crate::dfsdm::Sel::datin, crate::dfsdm::Sel::datin_ckin or crate::dfsdm::Sel::none.

ChannelSelectors8

The pin selectors handed to the crate::dfsdm::Dfsdm::configure_pins closure. Declare each transceiver’s pins with crate::dfsdm::Sel::datin, crate::dfsdm::Sel::datin_ckin or crate::dfsdm::Sel::none.

Dfsdm

DFSDM driver entry point.

DfsdmCommon

Holds references to the peripheral and the optional clock-output. Disables the RCC of the peripheral when dropped.
