Rotary Controller with Libreelec

Neophyte · February 22, 2017 at 4:53 PM

Hi.

I have build a kitchen radio for me and my wife with the RPi3 inside. I´m using the latest Libreelec Version (8.0.0) and everything works fine.

Now I want to control it with two Rotary Controllers like these: Rotary Encoder Module Brick Sensor Development KY-040: Amazon.de: Computer & Zubehör

I already put them in and connected them to the GPIO pins following this tutorial: Engineering(DIY): Control XBMC from the Raspberry PI GPIO's

In his Tutorial, Andrei mentioned the "carpc-controller" tool and the "io_config" (here´s a link to it GitHub - aistodorescu/carpc-controller: Raspberry PI controller
), which should be placed in /usr/bin.

How can I do that? It doesn`t work via FTP (I managed to copy them to the "videos" folder) and I don´t know how to move them with Putty (Linux Noob ).

And how do I get it to work on startup?

Thanks in advance!

LE is a readonly file system however instead of /usr/bin you could create /storage/bin folder and add PATH=$HOME/bin:$PATH to .profile. It

To run it at startup add the program to /storage/.config/autostart.sh

You may also need to add the LE addon RPI-tools which contains most modules for GPIO usage.

Thanks for your help.

I managed to create the folder /storage/bin and put both files in there.

I tried to start it with "sh carpc-controller" but it gave me this error:

Code

Kueche:~/bin # sh carpc-controller
carpc-controller: line 1: syntax error: unexpected word (expecting ")")

I was under the impression that this is an executable file... Do I have to compile it first with the files from github?

Also, what do I have to put in the autostart.sh?

I´m a total noob at this...

Looking at the github - yes it needs to be compiled

Well, I´ll try that tomorrow and post an update on how it´s going...

I need to go to bed, my head is spinning...

Ok, I tried the whole day to get this built. I just can´t do it. Im working on a windows machine and I don´t know how this works.

Is there someone here who could guild this for me and send me a link then?

thanks

Your best bet would be to use the RPi3 and Raspbian to compile it or use a Linux VM on windozs and cross compile on that (Will be faster)
