I’m running the Zumo SumoCollisionDetect sketch. Let me start off by saying I have two Zumo’s that I’ve put together. I have one Arduino UNO R3 SMD and I have one OSEPP UNO (also a SMD) The sketch runs fine on both shields with the Arduino UNO R3 SMD but it goes out to lunch on the OSEPP UNO at the lsm303.readAcceleration(loop_start_time); on line 222. I’ve really never seen someone derive a class in a sketch and my C++ isn’t anything that I know or use. It’s also a little weird that you have a LSM303 and an lsm303 in the same sketch.
Anyway all that being said, I’m guessing I have something going on with a register difference between the two boards but I can’t read C++ or figure out what the heck is going on in the derived class.
Have any ideas on how I can troubleshoot further … ?
