Member Function Documentation

◆ SetState()

Status pw::digital_io::DigitalIoOptional::SetState ( State  state)
inline

Sets the state of the line.

Callers are responsible to wait for the voltage level to settle after this call returns.

Warning
This method is not thread-safe and cannot be used in interrupt handlers.
Returns
  • OK: The state has been set.
  • FAILED_PRECONDITION: The line has not been enabled.
  • Returns other status codes as defined by the backend.

◆ SetStateActive()

Status pw::digital_io::DigitalIoOptional::SetStateActive ( )
inline

Sets the line to the active state. Equivalent to SetState(State::kActive).

Callers are responsible to wait for the voltage level to settle after this call returns.

Warning
This method is not thread-safe and cannot be used in interrupt handlers.
Returns
  • OK: The state has been set.
  • FAILED_PRECONDITION: The line has not been enabled.
  • Returns other status codes as defined by the backend.

◆ SetStateInactive()

Status pw::digital_io::DigitalIoOptional::SetStateInactive ( )
inline

Sets the line to the inactive state. Equivalent to SetState(State::kInactive).

Callers are responsible to wait for the voltage level to settle after this call returns.

Warning
This method is not thread-safe and cannot be used in interrupt handlers.
Returns
  • OK: The state has been set.
  • FAILED_PRECONDITION: The line has not been enabled.
  • Returns other status codes as defined by the backend.
