Hello,
I tried to use a MPU6050 on a GY-271 board with the Teensy LC. Basically it seems to work somehow, but the values from the MPU6050 seem to be OK with intermediate random values for acceleration sensor and completely random with the gyro sensor. The board also contains a HMC5883L magnetic sensor which works fine and a BMP180 which I didn't try. All connected to one I2C.
If I try the same board with exactly the same code on an Arduino Uno, all works fine. Thus, either there's a HW difference between Uno and Teensy LC or there's some library incompatibility.
I'd appreciate your suggestions.
Cheers,
Christof
