B4J Question Raspberry pi IR remote reciever?

[techknight]

For the project I am working on (yet another audio media player), I have some old IR remotes kicking around that dont go to anything anymore. I was wondering if I can use them in a B4J app?

I found a Pi library that handles IR remotes, its called lirc_rpi. But I cant find any cross references on getting it working outside of people wanting to "send codes", as well as B4J in general.

any ideas?

Check this tutorial: https://blog.byle.be/2016/02/04/lirc-on-raspberry-pi/

You can then read the GPIO status with jPi4J.

I saw that, but I am unsure how to get KEY_POWER in B4J?

There isn't enough information on this blog to understand how it works. I'm not sure what is sent to the data pin. You will need to look for more information.

Maybe this info would be useful. http://alexba.in/blog/2013/01/06/setting-up-lirc-on-the-raspberrypi/

It includes some links to github repositories to several trademarks IR commanders (config files --》code keys are different)

Well from what I have gathered, its a kernel level driver that maps the IR receiver to a /dev path on the device. So I assume I open the LIRC as an input device and read it like it was a keyboard? thats the thing I dotn know.

I dont want to send codes. I want to use a regular old remote that I program into the pi with lirc, and control my B4J app with it. thats all I am looking to do.

Actually, I just found this:

There is a JLIRC library that interfaces java to LIRC. So thats the answer I think. Except, how can this be ported to B4J? I never did grasp the concept of libraries/wrappers. over my head.
