Celsius sensor Pixhawk 4

[EliotBR (Eliot)]

Hi @uchiha,

@uchiha

Is it possible to connect the celsius sensor directly to Pixhawk I2CA port?

Yes, but there are integration issues at the moment - it can stop the Bar30 from working correctly if you’re using both (via an I2C splitter).

Now I also added a celsius fast response temprerature sensor on an I2C splitter but I don’t receive any values. Nothing in temperature(3). I only have the T° value from the BAR 30 in temperature(2).
Do you have any clue ?

I can replicate that here. We tried setting BARO_EXT_BUS = 3 , which got the Celsius to work but stopped the Bar30 from working. Wouldn’t suggest trying it - it’s not simple to get back the other way.

We’re looking into this, but not sure how long it will take to fix. It may just be a parameter issue, but may also require changes to ArduSub - we won’t know until we have a working solution.

How should the cable orientation on the JST connector be?

Not sure what you mean by this - the connectors only plug in one way.
