Mateksys F405-STD external compass


I am trying to connect an external compass (integrated into a GPS module) to my F405-STD. Without the compass everything works fine, but as soon as it is connected, I get “check BRD_TYPE: Baro: unable to initalize driver”. At first I thought, I had switched SDA/SCL, but the error is persistent, no matter in which order I connect the wires. Is this a known problem? Is there a way to solve it?

Sounds to me that your compass may not be connected properly or more likely it is faulty as it seems to be taking out the i2c to which the baro is connected.

The GPS/compass module worked with a pixhawk before. But I have another module and I will try that too.

I tried the other GPS/compass module and it is working! Thanks for the suggestion!

Glad you got it working.
