Pi4J :: Drivers
==========================================================================
GitHub Actions:
**THIS IS THE VERY START OF A NEW PROJECT. NO USABLE CODE IS YET AVAILABLE.**
This project contains driver implementations for various electronic components, using Pi4J V4+. Full description will be available on the Pi4J website at [Documentation > Using Drivers](https://pi4j.com/documentation/using-drivers).
## Using this Library
As this is library is still in early stage, you can only get a SNAPSHOT-version. To be able to use it in your project, you'll need to add both the dependency, and allow SNAPSHOTs:
```xml
...
com.pi4j
pi4j-drivers
0.0.1-SNAPSHOT
...
oss-snapshots-repo
Sonatype OSS Maven Repository
https://oss.sonatype.org/content/groups/public
false
true
oss-snapshots-M2-repo
Sonatype OSS Maven2 Repository
https://central.sonatype.com/repository/maven-snapshots
```
## The Case for A Pi4j “driver” Subproject
Document created by **Stefan Haustein**.
### Background
Pi4J used to have a set of iot hardware drivers, but they have been removed from the main project due to maintenance issues. Currently, there is the [pi4j-example-devices](https://github.com/Pi4J/pi4j-example-devices/) subproject containing drivers.
The examples cover several common devices and show how to use Pi4J to communicate with devices, but they are not suitable for external projects to “just” depend on.
### Proposal
The proposal here is to insert a new subproject `pi4j-drivers`, so the dependency structure for `pi4j-example-devices` is as follows:
```text
pi4j
|
pi4j-drivers
|
pi4j-example-devices
```
Ideally, this would not lead to an expansion of code size. Instead, drivers that are converted by the `pi4j-drivers` subproject will be deleted in the example-devices project – keeping the examples in place.
Examples for the `pi4j-drivers` project will be contained in the `pi4j-example-devices` project.
The drivers project will allow users to use covered hardware in a straightforward way, taking advantage of modern build / dependency management to keep them up to date.
### Volunteers
* @eitch
* Proper release management
* @stefanhaustein
* Contribute a set of drivers (currently have [Bmx280Driver.java](https://github.com/stefanhaustein/tablecraft/blob/main/src/main/java/org/kobjects/pi4jdriver/sensor/bmx280/Bmx280Driver.java) and [Scd4xDriver.java](https://github.com/stefanhaustein/tablecraft/blob/main/src/main/java/org/kobjects/pi4jdriver/sensor/scd4x/Scd4xDriver.java) and can offer a PiXtendDriver if there is interest, but it’s a bit more “esoteric”; would also like to add a character lcd driver after some more cleanup).
* Would be willing to take part in ownership, i.e guide contributors / do code review
* Would be willing to write PRs for removing redundant code from pi4j-example-devices
* @fdelporte
* Documentation on the Pi4J website
* Many others volunteered to contribute their existing driver implementations
* See this [Pi4J Discussion](https://github.com/Pi4J/pi4j/discussions/378)
