i2c without Mointessier hat
#1
Hi all,

Thanks for the effort with this excellent app.
My problem is how to read  pressure and temperature from my imu to put the data in signal k. Actually I get heading, heel and pitch from pypilot, but as data for pressure and temperature is not used by pypilot, is not read and is not send to signal k. 
I have the app i2c but when executed nothing happens, nothing opens.
All the rest, ais and gps are serial and work OK.

Thanks and regards,
Carlos.

What is the model of your pressure, temperature sensor?

what means "nothing happens" when you open I2C?

Thanks for your answer!

My imu is reported by pypilot as: Invensense MPU-9250/MPU-9255, the printed circuit reads MPU-92.65
It was working fine with openplotter older versions.

When I click I2C I was expecting to open a window to see the detected sensors, calibration, etc, but nothing opens. I can see the clock as doing something but after a few seconds it is over with no visible result.
I did un-install and re-install I2C twice with no results.

Thanks for your help,
Carlos.

Edit /home/pi/.openplotter/openplotter.conf and remove everything under the tag [I2C]

That is your IMU but what is your pressure sensor? check the detected addresses when you can open the I2C app

Thanks, now I2C works and detects the pressure, temperature and humidity as BME280 0/1/2. The pressure is displayed by Open CPN but not the air temperature, will keep checking.

Thanks, that was the problem!!

Hi!

Change Signal K Key "environment.inside.temperature" to the key "environment.outside.temperature"

select line 1 BME280 > then  Edit button

In the new box select Edit button

in the new box select in 'group' > "environment" ,in 'Keys' "outside.temperature"  >OK to go back

>OK to go back
