Module gpio

HIL for General Purpose Input-Output (GPIO) pins.

Structs

• InterruptValueWrapper
  Standard implementation of InterruptWithValue: handles an gpio::Client::fired and passes it up as a gpio::ClientWithValue::fired.

Enums

• ActivationMode
  Whether a GPIO is in the ActivationState::Active when the signal is high or low.
• ActivationState
  Some GPIOs can be semantically active or not. For example:
• Configuration
  Enum for which state the pin is in.
• FloatingState
  Enum for configuring any pull-up or pull-down resistors on the GPIO pin.
• InterruptEdge
  Enum for selecting which edge to trigger interrupts on.

Traits

• Client
  Interface for users of synchronous GPIO interrupts. In order to receive interrupts, the user must implement this Client interface.
• ClientWithValue
  Interfaces for users of GPIO interrupts who handle many interrupts with the same function. The value passed in the callback allows the callback to distinguish which interrupt fired.
• Configure
  Control and configure a GPIO pin.
• ConfigureInputOutput
  Configuration trait for pins that can be simultaneously input and output. Having this trait allows an implementation to statically verify this is possible.
• Input
• Interrupt
• InterruptPin
  The InterruptPin trait allows a pin to be used as either input or output and also to source interrupts.
• InterruptValuePin
  The InterruptValuePin trait allows a pin to be used as either input or output and also to source interrupts which pass a value.
• InterruptWithValue
  Interface that wraps an interrupt to pass a value when it triggers.
• Output
• Pin
  The Pin trait allows a pin to be used as either input or output and to be configured.
