I got an external compass to hopefully drive the interference down, but the documentation is not very straight forward.
1) what is the i2c pinout? I cant find this information anywhere with some precision, and the eagle files dont detail the pinout of the i2c df13 plug. THIS page talks about it briefly, so this is how i understand it:
starting from the inner most pin
-scl (mid inner)
-sca (mid outer)
can anyone confirm this?
2) what are the settings in mission planner that need to be in place in order to get an external compass to work? I have already severed the internal/on board compass' connection between the two pads.
In the compass setup window, is the "enable" radio button for the internal compass? or does this control using a compass all together? it doesnt appear that my external compass is working. will the cli compass test still work with an external compass? I have confirmed that my hmc5883l is getting 3.3v @ the breakout board...
thanks in advance
