Raw Blame History

Unreleased

v0.9.0 - 2024-03-16

  • rename from gpiod to gpiocdev.
  • move cli into its own repo - go-gpiocdev-cli.
  • remove SPI examples.

v0.8.3 - 2024-03-16

  • deprecate in favour of go-gpiocdev

v0.8.2 - 2023-07-28

  • switch tests from gpio-mockup to gpio-sim.
  • drop test dependency on pilebones/go-udev.
  • drop example dependency on warthog618/config.

v0.8.1 - 2022-12-31

  • add bananapi pin mappings.
  • fix config check in gpioset.

v0.8.0 - 2022-02-13

  • add top level RequestLine and RequestLines functions to simplify common use cases.
  • blinker and watcher examples interwork with each other on a Raspberry Pi with a jumper across J8-15 and J8-16.
  • fix deadlock in gpiodctl set no-wait.

v0.7.1 - 2021-10-10

  • restore LICENSE file for go.dev.

v0.7.0 - 2021-10-08

  • LineEvent exposes sequence numbers for uAPI v2 events.
  • Info tools (gpiodctl info and gpioinfo) report debounce-period.
  • gpiodctl mon and watcher example report event sequence numbers.
  • gpiodctl mon supports setting debounce period.
  • gpiodctl detect reports kernel uAPI version in use.
  • Watchers use Eventfd instead of pipes to reduce open file descriptors.
  • start migrating to Go 1.17 go:build style build tags.
  • make licensing REUSE compliant.

v0.6.0 - 2020-12-12

  • gpiod now supports both the old GPIO uAPI (v1) and the newer (v2) introduced in Linux 5.10. The library automatically detects the available uAPI versions and makes use of the latest.
  • applications written for uAPI v1 will continue to work with uAPI v2.
  • applications that make use of v2 specific features will return errors when run on Linux kernels prior to 5.10.

Breaking API changes:

  1. The event handler parameter has been moved from edge options into the WithEventHandler(eh) option to allow for reconfiguration of edge detection which is supported in Linux 5.10.

    Old edge options should be replaced with the WithEventHandler option and the now parameterless edge option, e.g.:

    s/gpiod\.WithBothEdges(/gpiod.WithBothEdges, gpiod.WithEventHandler(/g

  2. WithBiasDisable is renamed WithBiasDisabled. This option is probably rarely used and the renaming is trivial, so no backward compatibility is provided.

  3. FindLine has been dropped as line names are not guaranteed to be unique. Iterating over the available chips and lines to search for line by name can be easily done - the Chips function provides the list of available chips as a starting point.

    Refer to the find command in gpiodctl for example code.
