MPU6050, doesn't work fine

[ASibi.2]

Hi, i've made a project called "propeller arm". This project is composed of a dc motor(controlled by a mosfet) and an IMU(MPU6050). I've used a complementary filter to measure the tilt angle and this works fine. For the throttle control i've used a library PID found on internet and works fine. When i turn on the motor the MPU become "crazy" and doesn't communicate with my mcu and im see on my oscilloscope the value of SDA(HIGH still) and SCL(LOW still). That situation is very strange and i don't know why.

Some times this time happens even with the engine not powered. I've just buy a new MPU but that problem persist in both sensor.

Thank's all for the replys.

Best Regards Antonio.

with the debug i've see that path. The only thing what it make is the communication(I2C) between MPU->MCU

Any idea?
