|
||
|
|
- 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](https://reuse.software/) 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.:
|
||
|
|
|
||
|
|
```sed
|
||
|
|
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.
