I am having issues with the Arduino sketch: MPU6050_DMP6. As I rotate the mpu, the angle readings never go beyond about +/-84 degrees. What I mean is that if I rotate the mpu to a 90 degree position, I get a reading of 84 degrees, and if I continue to rotate, the angle starts to decrease again. You can imagine the graph of y = 84 sin([PI * X] / 180) to model my situation, where x is the actual angle of the mpu and y is the value read by it. My MPU6050 never used to do this. Is it possible it's gotten old and broken?
Hi I'm new to Arduino and I'm trying to use a 6DOF IMU (the MPU-6050) along with the i2cdevlib. I've been able to set the libraries and to execute a sketch in order to calculate the offset of the IMU starting from the raw data. Now I'm trying to execute the example code that i found on the github of the i2cdevlibhttps://github.com/jrowberg/i2cdevlib/blob/master/Arduino/MPU6050/Examples/MPU6050_DMP6/MPU6050_DMP6.ino setting the output in the YPR modeCode: #define OUTPUT_READABLE_YAWPITCHROLL with and without my offset parameters. In both sketches I found the same issue. The data on the serial shift from the initial position for 5-8 second showing an increment of several degrees (depends on the cases but usually there are 12-25 degrees) of the YPR angles without moving the IMU. The same thing happen with the Euler anglesCode: #define OUTPUT_READABLE_EULER I've tried also to execute the quaternion output modeCode: #define OUTPUT_READABLE_QUATERNION which i don't know how to read (I'm just started learning about this) but the value I read on the serial seems to stay "stable". I might solve this with a delay from the turn on which allow me to see of how much degrees the IMU "virtually moved" and then subtract that value to future reading (such as another offset) but i find this not usefull since I need the IMU to have the right angles on the turn on. Thanks for reading, hope someone could help me
