Rust GPIO

Deals with GPIO access on Linux and bare metal embedded systems, through sysfs and direct memory access. Planned to works on stable Rust 1.9.

Roadmap

• [x] GPIO write support
• [ ] Read support
• [ ] Interrupt support
• [ ] Split to allow building without std
• [ ] Compile using stable

Other libraries

Other libraries can be found on crates.io. These include:

• sysfs_gpio <https://github.com/rust-embedded/rust-sysfs-gpio>_ handles GPIO only via SysFS, but exposes all features. Slightly lower level.
• cylus <https://github.com/Vikaton/cylus>_ Documentation is dead, does a few questionable things like unwrapping()

• cupi <https://github.com/cuprumpi/cupi>_ Most comprehensive GPIO library, includes almost all features planned for gpio. Does not use volatile.
