Danny,
I've not used C++, but I have seen problems like this. For me, it happened when
the firmware in my brick didn't match the firmware I compiled the program to
use. However, it doesn't sound like that's the problem your having.
I'd suggest commenting out all the C++ code, and see if you still get the
problem.
Actually, my guess is that the c++ library has not been updated to work with the
latest version of BrickOS. I think a couple years ago the motor control stuff
was moved in memory, and I don't recall anyone saying anything about updating
the c++ code.
If you really want to use c++, you may need to look into the motor.h and
motorpair.h files, and figure out what's going on. However, give the lack of
reply to this post, you may have to figure it out yourself. :(
I hope you come up with something
Steve
