Hello,
I try to build a Quadcopter using the dji F450 Flame Wheel and an Arduino Due. As sensor i use the FreeImu board.
The sensor reading are very steady when i test them without any motor running. But when i increase the motor speed to about 50% the sensor readings get really weird. The issue appears not only on the Compass but also on Gyros and Accelerometer. So i don't think that the cause are inductive interference from the motors.
Had someone similar experiences? I use the FreeImu library to read out the sensor, to control the ESC i use the Servo.h.
Thanks for your help.
