This library is little hard to use ... #16

The example code works fine on Mega2560, but it won't work when integrated in my own code.

At first I was lured into debug mpu_init() because it always return error code until the return value in example is printed out.

Then I found that the calling order of dmp_enable_feature() and mpu_set_dmp_state() in example may be wrong because when I made the mpu_set_dmp_state() last call in mympu_open () it worked.

The big question is why the example works fine ...

Are you sure you have not hit any memory/heap limit? The solution is not very streamlined so might need a lot of resources

The solution for now is give raw data from register to Raspberry Pi to calculate orientation. Thank you for reply.
