I need advice on testing and debugging a Zumo Shield v1.2 (purchased as a pre-assembled robot). Newly downloaded libraries, Arduino IDE 1.6.7.
When LMS.init() is called, it hangs and does not return. The problem appeared in the collision sumo sketch, so I’ve isolated it with the Zumo LMS303 Serial example so nothing else is going on. The Serial monitor shows the loop when compass.init() is commented out in setup(), but never gets past the init() otherwise.
This is one of a set for a robot club and when the connected Arduino is on this one, nothing happens - transferred to the other Zumos, the Arduino/Zumo combo works.
I’m wondering how to systematically test a shield for functionality to see what’s up.
