OpenSignals on Raspbian on a Rasperry Pi 3

Postby MaxLindner » Fri May 13, 2016 10:19 am

Hello together :),

I am an engineering student and I have to do a project with bitalino and raspberry. I have problems to install and run OpenSignals on the Raspbian OS on the Rasperry Pi 3. Do you have a step-by-step manual for that? Sorry, but I am very new to the raspberry, linux and bitalino.

The project itself is a case with a touchscreen, raspberry and the bitalino. You can bring it everywhere and do measurements.

Thanks,

Max :)

Hi and welcome to the BITalino community :)

In order to install OpenSignals (r)evolution on Raspbian, you need to follow these steps:

1. Install Google Chrome: https://www.google.com/chrome/

2. Download the OpenSignals (r)evolution tarball: http://downloads.plux.info/OpenSignals/OpenSignals_(r)evolution_Linux_amd64_Beta.tar.gz

3. Extract the downloaded tarball.

4. Open Terminal and run:

Code: Select all

cd {extracted_tarball_directory}
make
make install

5. Start OpenSignals (r)evolution:

Search for it in the menu or open Terminal and run the command:

Code: Select all

opensignals


Let us know if everything works correctly and good luck ;)

Hello again,

thanks for your reply.

Sorry for the late reply but I had some struggles with the hardware and now I have tried to deal with the software problem.

I did everything as you described. But there is a problem. You gave me the "amd-architecture" and you need an "arm-architecture" for a rasperry pi.

I replaced the deliverd Phyton with the System Phyton. But the problem with the architecutre specific "plux.so" remains.

Could you provide a compiled version for the amr-architecture or provide the source code of "plux.so"?

I have to finsih the project in the next 2 weeks, it would be very very nice if you could reply fast ;).

Thank you in advance.

Greetings,

Max :)

Hello again :)

Good job on changing to the system Python. Make sure you don't miss any dependencies :)
When outside of Windows, OpenSignals uses the BITalino Python API that connect to the device via Serial Port.
This means that if OpenSignals doesn't start, the problem is somewhere else.
What is the console printing out?
Does the command bellow successfully opens a Chrome windows?

Code: Select all

google-chrome

Thank's for the fast reply :)...

The Browser is Chromium, the Open Source Software of Google Chrome. There is no original "Google Chrome" on Pi. But it opens the chromium browser and the "OpenSignals-Sign" is there, but that's it.

This is written in the terminal:

pi@raspberrypi:~ $ opensignals
Unable to import PLUX API
Unable to import PLUX API

Hi again,

So it does open the browser with the blinking OpenSignals cloud, correct?
Do you have your Chromium Browser up to date? If you don't, please update and try again. If you do, can you send me the version you have?
Can you open the browser console (F12 or Settings > More Tools > Developer Tools) and send me what is in the console?

Yes exactly, it does open the browser with the blinking OpenSignals Cloud.

I think it is up to date.

This is the version I have:

Chromium 50.0.2661.102 Built on Ubuntu 15.04, running on Raspbian 8.0

I have installed the same Chromium version you do and it works fine.
The console shows no errors?
