I'm using a Magdwick filter, which works pretty ok, however I've noticed that small angle displacements less than 0.

I did at one point completely remove the filter and calculate the angle via:. However there were angle "spikes" for lack of a better word during quick angle changes that caused the regulator to over compensate and be completely unstable. Here is my truncated code relevant to sensor and the Madgwick filter, however I can include if requested, the entire program.

However I am of course completely willing to use another filter, kalman? On top of that, here is a youtube video of the system hanging in the stable equilibrium, Here the regulator works in the current code implementation, however for small disturbances, the angle doesn't update accurately enough, in this position it doesn't matter, however in the inverse angle Pi this is critical and the cause of my initial question.

Some sensors have a filter inside to reduce noise. Can you test the raw values from the sensors? All the libraries and the calculations are with float, you gonna lose some accuracy.

The Arduino Due can use double precision. There is a weird calculation in invSqrt. Can someone look into that to see if that bit operation on a float is correct? Can you show a photo or draw a picture? Ah, yes that was my madgwick implementation, I will add it to the question An accelerometer is sensitive for small changes and vibrations and is noisy. The gyro drifts.

When also a magnetometer is added, the AHRS filter can make a good steady output. The AHRS filter is for objects like a plane. You only need the angle in one dimension. Ahh, yes, actually that makes sense, my system is a 1 dof system, in reality I only need the angle Is the module powered with 3.

The block has two output ports, Magnet and Accel. The number of output ports vary depending on the active sensors that you select.

Interleaved magnetic and acceleration data is available at ODR rates of up to Hz. Place the board face up on a table, with the dot to the top-right corner of the FXOS 6-Axes chip.

At this position, the X-axis points away from you, the Y-axis is horizontal and points to the left, and the Z-axis is vertical and points up. The direction of the arrows shows the positive direction of the reading for the accelerometer and the magnetometer. When you tilt the board along the X, Y, and Z axes of the chip, this illustration shows the acceleration and the magnetic field. Hold the board so that the board faces you and the dot is to the top-right corner of the chip.

The acceleration of gravity is static because the chip is stationary. In the resultant [1x3] vector, the value of the X-axis ranges between the full-scale range value that you specify in the Acceleration full scale range parameter. The magnetometer on the chip measures the earth magnetic field along each sensor axis.

In the resultant [1x3] vector, the first value that represents the magnetic strength at the X-axis is minimum. The block has two output ports. The number of ports varies depending on the active sensor that you select in the Active sensor list.

The block outputs the magnetic field as a [1x3] vector.

The block outputs the acceleration as a [1x3] vector. Each value represents the measurement of the acceleration in g 9. Accelerometer only — When you set the Active sensor parameter to Accelerometer onlythe block configures an output port. The port on the block is labeled as Accelindicating that the block outputs the measurement of the acceleration from the accelerometer.

The acceleration is measured along the X, Y, and Z axes of the chip. The ODR ranges from 1. Magnetometer only — When you set the Active sensor parameter to Magnetometer onlythe block configures an output port.

The port on the block is labeled as Magnetindicating that the block outputs the measurement of the earth magnetic field from the magnetometer.

Please be positive and constructive with your questions and comments. I did not realize the gyro tells you rate of change of the angle in the x, y, z directions. What I want to do is get the gyro to tell me the actual angle, preferably in degrees, and use that as my data. Also I will use the gyro data to satisfy a parameter that I am going to write, but that step I can figure out. All I need is the gyro to tell me the angle in which the sensor is at.

I have read that you can do this by taking the gyro data and using data from an accelerometer and from that you can calculate angle.

The problem is I do not know how I should code this. Here are my two separate codes, the gyro code and acceleration code respectively Check your wiring! Any tips on coding and or how I should tackle this problem is much appreciated. It can only tell you the rate of rotation.

From that you can estimate the relative angular displacement by integrating the rotation rate over time, but be aware that this is subject to drift. The accelerometer can give you an absolute angle relative to vertical, since there is a constant 1G acceleration in the vertical axis due to gravity. The Magnetometer can give you an absolute angle relative to magnetic north due to the relatively stable magnetic field of the earth.

To determine orientation in real-time, an IMU generally combines the outputs of the accelerometer, magnetometer and gyro. I know you can get better results by fusing the gyro data with acceleration and magnetic direction data.

The question is, how do I do this? How do I take gyro, acceleration, and magnetic direction and transform that data into an angle?

So how would I code an algorithm to give me an angle in the X and Y directions from the gyro, acceleration, and magnetic direction data??? I am now trying to calibrate my sensors using the ahrs calibration code using my "precision" 9DOF board. I can get raw gyro data but am unable to get raw accelmag data. I am trying to calibrate it and then enter the calibration data into the mahony code so I can get euler angles for orientation.

You can get the raw values from these immediately after a call to getEvent. I posted it to illustrate that those data members are declared as 'public', so you can reference them directly in your code. Are you saying the best way to control outputs would be to build your sketch within the fusion sketch? That can serve as input to your control algorithm for your servos. Return to Arduino.
