Module rp2040_hal::pio

Programmable IO (PIO) See Chapter 3 of the datasheet for more details.

Structs

• InstalledProgram
  Handle to a program that was placed in the PIO’s instruction memory.
• Interrupt
  PIO Interrupt controller.
• InterruptState
  Provides easy access for decoding PIO’s interrupt state.
• PIO
  Programmable IO Block
• PIOBuilder
  Builder to deploy a fully configured PIO program on one of the state machines.
• Running
  Marker for an initialized and running state machine.
• Rx
  PIO RX FIFO handle.
• SM0
  First state machine.
• SM1
  Second state machine.
• SM2
  Third state machine.
• SM3
  Fourth state machine.
• StateMachine
  PIO State Machine with an associated program.
• StateMachineGroup2
  Group of 2 state machines, which can be started/stopped synchronously.
• StateMachineGroup3
  Group of 3 state machines, which can be started/stopped synchronously.
• StateMachineGroup4
  Group of 4 state machines, which can be started/stopped synchronously.
• Stopped
  Marker for an initialized, but stopped state machine.
• Synchronize
  Type which, once destructed, restarts the clock dividers for all selected state machines, effectively synchronizing them.
• Tx
  PIO TX FIFO handle.
• UninitStateMachine
  PIO State Machine (uninitialized, without a program).

Enums

• Buffers
  Buffer sharing configuration.
• InstallError
  Errors that occurred during PIO::install.
• MovStatusConfig
  Comparison used for mov x, status instruction.
• PinDir
  Pin direction in the PIO
• PinState
  Pin State in the PIO
• PioIRQ
  Id for the PIO’s IRQ
• ShiftDirection
  Shift direction for input and output shifting.

Traits

• PIOExt
  PIO Instance
• StateMachineIndex
  State machine identifier (without a specified PIO block).
• ValidStateMachine
  Trait to identify a single state machine, as a generic type parameter to UninitStateMachine, InitStateMachine, etc.
