Hardware : Gravity: BNO055+BMP280 intelligent 10DOF AHRS from DFRobot & STM32F407VGT Discovery
Method: Reading Euler angles using I2C
Problem: There are spikes in reading data.
Tests:
1- Tried with another IMU (L3G4200D and LSM303DLHC) and I2C working perfectly fine. This means STM32F407VGT Discovery is OK.
2- Tried other fusion outputs (Quaternion and Linear Acc) and reading spikes. So the problem is not about Euler registers.
3- There is no vibration at all just using my hand to rotate very slowly sometimes faster. Speed doesn't change the results. I have always reading spikes.
Files added:
1- Excel table for my reading logs. (Obtained from STM Studio)
2- 1 PNG images from STM Studio that show spikes.
3- 1 PNG image from Excel table where spike can clearly observable.
Questions:
1- Is it a problem that occurs in any BNO055 or my BNO055 is damaged?
2- What is the probable cause and how to avoid it?
3- My goal is to use this IMU in Quadcopter. Any advice about using another model? I am not good with filters like Kalman so I have to have an IMU that calculates angles for me.
This is my second post. The first one never answered. Please I need some answers.
Emre,
