# HAL for working with atsamd21 devices This crate provides a type-safe API for working with atsamd21 based devices. Currently this crate supports `atsamd21g18a` or `atsamd21e18a` (selectable via the `samd21g18a` or `samd21e18a` features), and should be able to support other variants in a similar fashion; pull requests for this are welcomed! ## Examples? Check out the metro_m0 board support crate examples: https://github.com/wez/atsamd/tree/master/metro_m0/examples ## Deprecated This crate has been replaced by atsamd-hal, which combines both atsamd21 and atsamd51 support.
