OpenMarine

Hi,

the i2c app (2.1.0) on my system wont open. I'm on Pi 4, tried to open it from Terminal. First Error was "Could not open file /dev/i2c-0...". After adding i2c-0 to the config text, this is gone, but now i still get

File "/usr/lib/python3/dist-packages/openplotterI2c/openplotterI2c.py", line 222, in readSensors
if i['pipeElements'][0]['options']['type']=='SignalK':
KeyError: 'type'

There is no entries under [i2c] in openplotter.conf.
Any Ideas how to fix it?

Thanks!

"After adding i2c-0 to the config text, this is gone"

That error is expected and just informative so remove what you have done in config file to avoid collateral effects.

I think I know what happens, please could you post here the contents of /home/pi/.signalk/settings.json file?

Thanks strly,

Interesting, it seems that your GPSD connection in Signal K server is causing the crash of i2c app. I will fix this and will send you a test package.

Is this GPSD connection working? that is an old connection that was not ported to the Signal k server GUI, wondering if it would be worth adding a GPSD option in SK GUI. Tkurki?

Test this package, it should fix your problem:

Please report so we can go to production.

Perfect, works fine! Yes, the gpsd provider is working.
Now, as I wanted to use i2c for the INA219 current sensor: is there a way to add it in the i2c-app?

Thank you!

OK, thanks!

Adding support for the INA219 is in the TODO list but I do not have neither the sensors nor instruments required to develop this at home/prison. Here in Catalonia there is a total lockdown and I will not be able to go to the lab until April 13 at least Sad

Marking this thread as solved.

FYI. GPSD connections have been added to Signal K server 1.27.1. You should replace your manual GPSD connection.
