Module embassy_nrf::ppi

Programmable Peripheral Interconnect (PPI/DPPI) driver.

The (Distributed) Programmable Peripheral Interconnect interface allows for an autonomous interoperability between peripherals through their events and tasks. There are fixed PPI channels and fully configurable ones. Fixed channels can only connect specific events to specific tasks. For fully configurable channels, it is possible to choose, via software, the event and the task that it will triggered by the event.

On nRF52 devices, there is also a fork task endpoint, where the user can configure one more task to be triggered by the same event, even fixed PPI channels have a configurable fork task.

The DPPI for nRF53 and nRF91 devices works in a different way. Every channel can support infinitely many tasks and events, but any single task or event can only be coupled with one channel.

Structs

• AnyConfigurableChannel
  The any configurable channel can represent any configurable channel at runtime. This can be used to have fewer generic parameters in some places.
• AnyGroup
  A type erased PPI group.
• AnyStaticChannel
  The any channel can represent any static channel at runtime. This can be used to have fewer generic parameters in some places.
• Event
  Represents an event that a peripheral can publish.
• Ppi
  PPI channel driver.
• PpiGroup
  PPI channel group driver.
• Task
  Represents a task that a peripheral can do.

Traits

• Channel
  Interface for PPI channels.
• ConfigurableChannel
  Interface for PPI channels that can be configured.
• Group
  Interface for a group of PPI channels.
• StaticChannel
  Interface for PPI channels that cannot be configured.
