Here is my problem or probably i should say my short comprehension of how the system behaves about compasses.
I have 2 external compasses connected to the second I2C port of my PH 2.1 (maybe i should connect one to the gps port i2c and one to the second i2c port)
PH 2.1 has 2 additional internal compasses too.
Now how can i be certain that the system uses the 2 external compasses (if it is possible) and not the external ones?
I tried to set compass 1 and compass 2 on mission planner as external and disable (not use) the third compass, but this doesn’t work, the internal compasses are still there (at least one) and the 2 external behave erratically.
So at the bottom of the problem i think i don’t have a very clear picture on how to force the system to use a particular compass and how to check to make sure it does.
Hope my doubts are clear enough, if not i’ll answer to any question to make it clearer.
I know this argument has been talked about thousands of times and i read all the previous discussion but i couldn’t really understand how the system works and based on what algo the compasses are choosen.
