Module rp2040_hal::pio
source · [−]Expand description
Programmable IO (PIO) See Chapter 3 of the datasheet for more details.
Structs
Handle to a program that was placed in the PIO’s instruction memory.
PIO Interrupt controller.
Provides easy access for decoding PIO’s interrupt state.
Programmable IO Block
Builder to deploy a fully configured PIO program on one of the state machines.
Marker for an initialized and running state machine.
PIO RX FIFO handle.
First state machine.
Second state machine.
Third state machine.
Fourth state machine.
PIO State Machine with an associated program.
Marker for an initialized, but stopped state machine.
Type which, once destructed, restarts the clock dividers for all selected state machines, effectively synchronizing them.
PIO TX FIFO handle.
PIO State Machine (uninitialized, without a program).
Enums
Buffer sharing configuration.
Errors that occurred during PIO::install.
Comparison used for mov x, status instruction.
Pin direction in the PIO
Pin State in the PIO
Shift direction for input and output shifting.
Traits
PIO Instance
State machine identifier (without a specified PIO block).
Trait to identify a single state machine, as a generic type parameter to UninitStateMachine,
InitStateMachine, etc.
