Java wrapper class for this lib

[konsultaner]

Hey! Thank you for your great work! I currently try to build my own wordclock using the NaoPixels. I wrote a Java-Wrapper for your library. Maybe you want to link my project with the hint of an existing Java Wrapper.

Awesome! Thanks. That's great. One question however as I'm wondering why you needed to use the gpio_alt.c code. I believe with the right defines, this should be taken care of by the ws281x library itself. Maybe I'm missing something.

@jgarff Oh, I didn't know that. I followed the instructions from the adafriut website, where they described how to bring audio to the Pi Zero. I did not go into detail with the ws281x lib at this point.

I've managed to do this using swig: https://github.com/limpygnome/build-tv/tree/master/libs/neopixel-ws281x-lib

FYI another Java Wrapper (using JNI): https://github.com/mattjlewis/diozero/tree/master/diozero-ws281x-java

I was looking for a java wrapper for this and came across this issue. I looked at the solutions proposed here and liked the SWIG approach. That solution however was embedded in a larger project, so I decided to take that concept and create my own standalone library based on it. I also used some code to load in the generated .so file, as well as a convenience bash script to build that .so file remotely. The source for my library can be found here: https://github.com/mbelling/rpi-ws281x-java.

I also pubished an initial version to maven central, so build tools like maven and gradle can pull it in: http://search.maven.org/#artifactdetails%7Ccom.github.mbelling%7Crpi-ws281x-java%7C1.0.0%7Cpom

@mbelling since you seem to have the most recent and standalone Java wrapper, would you care to bring it under the rpi-ws281x umbrella to draw more attention and, hopefully, ongoing contributions to it?

See: https://github.com/jgarff/rpi_ws281x/issues/267

It would live under here: https://github.com/rpi-ws281x

I've also got a Java wrapper for the library. Sounds like we should swap notes and consolidate! Check out https://github.com/hackerjimbo/PiJava/tree/master/Jimbo/Devices/WS2811

@Gadgetoid I'd be happy to. I have not moved a project before, so I'll probably need to read up on how I go about doing that. I'll see if I can get some time soon to push what changes I have locally at home and work on moving it over.

I think all Java discussion should now move to the Java repository, so I'll close this Issue for the time being!
