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.
