A Rust library for accessing GPIO lines on Linux platforms using the GPIO character device.

This is the equivalent of libgpiod, but in pure Rust.

gpiocdev provides a high level API for accessing GPIO lines from Rust applications.

You probably want this one.

gpiocdev-embedded-hal provides embedded_hal traits for gpiocdev Requests.

Also provides a simplified interface that may be useful for basic use cases.

gpiocdev-cli provides a command line tool to access and control GPIO lines.

The tool can be useful for writing scripts accessing the GPIOs, and for debugging GPIO setups.

gpiocdev-uapi provides a thin safe Rust wrapper around the character device ioctls.

The gpiocdev crate provides a higher level abstraction, so you should use that unless you have some particular interest in calling the Linux GPIO ioctls directly.
