Version 2.2.0 is
This is a polish and features update. I know a v3 was
promised but we decided to punt on breaking changes
since there was too much great stuff to bake into the v2 branch.
The new release contains 79
changes by 7
contributors for a diff stat of
235 files changed, 9279 insertions(+), 3103 deletions(-).
- gpioreg: The GPIO registry had
intensive structural changes in preparation for support of dynamic GPIOs, e.g.
over USB. It completely discarded the principle of pin numbers, and only
refers to pin names. Number-based aliases are still kept, but they need to be
the decimal textural string representation. Added Unregister.
- Warning: The primary side effect is that alias evaluation via
gpio.RealPin may have to be
done in places where it ‘happened to work’ previously.
- conn: Removed a ton of indirect
dependencies on reflect. This is to make
conn essentially ‘reflect-free’, which would enable more embedded uses cases.
String() to all objects, in preparation to requiring it in
- Refactored all examples to be copy-pastable.
- periph: Added undocumented support for a new
After(), which enables significantly more
parallelism in driver
loading. This function will be added to
periph.Driver in v3.
- cmd: Added support for a new build tag
periphextra. This makes the executables use
hostextra.Init() instead of
- Warning: If you use a pattern like
go build ./cmd/periph-info/main.go,
this will not work anymore as
each executable is now multiple source files. The correct way is
go install periph.io/x/periph/cmd/periph-info
- gpiotest: Added
- onewire-list to display
registered 1-wire buses.
I want to give a special thank to all the contributors that made this release
I (@maruel) did the rest, including the release
process and the gohci test lab.
