Programmable IO (PIO)
See Chapter 3 of the datasheet for more details.
Structs§
- Installed
Program - Handle to a program that was placed in the PIO’s instruction memory.
- Interrupt
- PIO Interrupt controller.
- Interrupt
State - 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.
- State
Machine - PIO State Machine with an associated program.
- State
Machine Group2 - Group of 2 state machines, which can be started/stopped synchronously.
- State
Machine Group3 - Group of 3 state machines, which can be started/stopped synchronously.
- State
Machine Group4 - 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.
- Uninit
State Machine - PIO State Machine (uninitialized, without a program).
Enums§
- Buffers
- Buffer sharing configuration.
- Install
Error - Errors that occurred during
PIO::install. - MovStatus
Config - Comparison used for
mov x, statusinstruction. - PinDir
- Pin direction in the PIO
- PinState
- Pin State in the PIO
- PioIRQ
- Id for the PIO’s IRQ
- Shift
Direction - Shift direction for input and output shifting.
Traits§
- PIOExt
- PIO Instance
- State
Machine Index - State machine identifier (without a specified PIO block).
- Valid
State Machine - Trait to identify a single state machine, as a generic type parameter to
UninitStateMachine,InitStateMachine, etc.
