Change Log

master - Unreleased

Changed

0.6.2 - 2024-05-13

  • Minimum supported Rust version updated to 1.65.0
  • The crate's Error type can now be converted to a std::io::Error using From / Into.

0.6.1 - 2021-11-22

Changed

  • Updated nix to version 0.23.
  • Updated mio to version 0.8.

0.6.0 - 2021-09-24

Changed

  • [breaking-change] Renamed use_tokio feature async-tokio.
  • Migrated to tokio crate version 1.
  • Updated nix to version 0.22.
  • Updated mio to version 0.7.
  • Updated futures to version 0.3.
  • Minimmum supported Rust version updated to 1.46.0.

0.5.3 - 2018-04-19

Fixed

  • Relaxed path restrictions on Pin::from_path to allow for directories outside of /sys/class/gpio, required for some SOCs that symlink outside of that directory.

0.5.2 - 2018-03-02

Changed

  • Add support for active_low configuration.
  • Remove dependency on regexp
  • Update nix to 0.10.0

0.5.1 - 2016-06-17

Changed

  • The crate now compiles (to more-or-less nothing) on OSX which can be useful in some contexts.
  • Multiple warnings from clippy were addressed
  • Support for some older versions of rust was dropped and things like ? are now used in the codebase.
  • Additional traits like Copy added where appropriate in some places.

0.5.0 - 2016-12-18

Changed

  • Support for asynchronous polling for changes using tokio/futures is now supported.
  • Minimum supported version Rust for 0.5.0+ is now 1.10.0

0.4.4 - 2016-08-26

Fixed

  • A couple issues were fixed that limited the circumstances where Pin::from_path would work in various environments.

0.4.3 - 2016-06-22

Changed

  • Added from_path constructor to allow for use of the library with symlinked GPIOs to interact with things like the IOs exported by gpio-utils.
  • Bumped Nix dependency to version 0.6.0 (removes some compile warnings)

0.4.2 - 2016-04-17

Changed

  • Pin now has an is_exported() function

Fixed

  • Moved to nix 0.5 which fixes problems on some architectures

0.4.1 - 2016-04-8

Changed

  • A few additional traits are derived for types exposed by the library.
  • Links/Docs updated with move to rust-embedded Github org

0.4.0 - 2015-12-04

Changed

  • We now expose our own Error type than using io::Result. This allows for better errors to be provided from the library. This breaks backwards compatability.

Fixed

  • Only open file for reading when reading value from file

0.3.3 - 2015-09-25

Added

  • get_pin method added for accessing pin number
  • get_direction method added for querying Pin direction

Changed

  • Updates/Fixes to documentation
  • Non-functional code refactoring and cleanup

0.3.2 - 2015-07-13

Fixed

  • We now work with the latest version of nix

0.3.1 - 2015-05-21

Fixed

  • Converting from a nix error to an io::Error has been simplified and updated to work with future versions of nix

Changed

  • Documentation now refers to package as sysfs-gpio with a dash instead of an underscore as per common convention. The package name on crates.io cannot be changed right now, however.
  • Documentation updates.

0.3.0 - 2015-04-20

Fixed

  • Updates to work with latest rust nightlies

Added

  • Support for interrupts on pins was added via epoll. This is an efficient and performant way to wait for a pin to change state before performing some operation.

0.2.1 - 2015-04-06

Fixed

  • Library updated to work with latest nightlies (~1.0.0 beta). Due to std situation, still need to depend on a few deprecated features for the examples (synchronous timers).

0.2.0 - 2015-03-19

Changed

  • The core module has been removed in favor of putting all structs, functions, and macros directly in the sysfs_gpio crate.

Added

  • Project now publishes documentation and has travisci support
  • Added with_exported method taking a closure for more convenient export/unexport in all cases.

Fixed

  • Fixed a critical bug that resulted in unexport never actually unexporting GPIOs.

0.1.1 - 2015-03-17

Added

  • Added try_unexport! macro
  • Include additional documentation for cross-compilation
  • Added poll example showing input functionalty

Fixed

  • Fixed bug preventing the correct operation of get_value. In 0.1.1, this function would always fail.

0.1.0 - 2015-03-15

Added

  • Initial version of the library with basic functionality
  • Support for export/unexport/get_value/set_value/set_direction
