Implementation of theembedded-hal traits for Linux devices

This project is developed and maintained by theEmbedded Linux team.

Since Linux kernel v4.4 the use of sysfs GPIO was deprecated and replaced by the character device GPIO.Seegpio-cdev documentation for details.

This crate includes feature flaggpio_cdev that exposesCdevPin as wrapper aroundLineHandle fromgpio-cdev.To enable it update your Cargo.toml. Please note that in order to preventLineHandle fd from closing you shouldassign to a variable, seecdev issue for more details.

linux-embedded-hal = { version = "0.4", features = ["gpio_cdev"] }

SysfsPin can be still used with feature flaggpio_sysfs.

Withdefault-features = false you can enable the featuresgpio_cdev,gpio_sysfs,i2c, andspi as needed.

This crate is guaranteed to compile on stable Rust 1.65.0 and up. Itmightcompile with older versions but that may change in any new patch release.
