imuFilter - v1.6.3

changes:

• Fixed broken vel initial value in 'accIntegral.cpp' and 'accIntegral.h' to vector {0,0,0}

Credit goes to jindrichus and mittlc for pointing out these problems.

imuFilter - v1.6.2

Changes:

• Removed gravity input. Assume 1g acceleration at rest
• Updated readme references
• Set accelerometer offsets to zero in examples

imuFilter - v1.6.1

Changes:

• Fixed issue with heading update and acceleration integral using different scales for acceleration vector.
• Added default values for imuFilter state to prevent undefined initialization.

imuFilter - v1.6.0

Changes:

• Added timeStep() function to imuFilter. Allows measuring change in time between updates.
• Removed accIntegral::updateVel. Rather, update() was overwritten to not have to independently call imuFilter::update()
• Acceleration integration and heading update both use the same acceleration uncertainty.

imuFilter - v1.5.0

Changes:

• Added acceleration integration. The "accIntegration" class provides a short-term estimate of velocity.
• Added vector inputs to imuFilter functions "setup" and "update".

imuFilter - 1.4.1

Updated version to make compliant with library manger requirements. Originally released in: Nov 10, 2022.

Changes:

• Converted to x.x.x version format.
• Converted from 2nd order filter to kalman filter.
• Placed sensor fusion setup as last step in examples. Removes excessively large time step.

imuFilter - 1.3.0

Initially released on Oct 30, 2022. Changes:

• Factored updateTimer function to use one millis() call
• Added kalman filter to check acceleration and modulate filter response
• Included comments on kalman filter in readme file

imuFilter - 1.2.0

Initially released on Oct 16, 2022. Changes:

• Removed template and moved GAIN to input of "update" function.
• Added default gain.
• Added input to "update" to scale the gain by the time step.
• Removed redundant code in "setup" and "update".
• Updated readme to display pretty equations.

imuFilter - 1.1.0

Originally released on Oct 13, 2022. Changes:

• Removed array-based vector and quaternion operations.
• Replaced arrays with vectors and quaternions from "vector_datatype" library.
• Removed time-scaling of filter coefficients.
• Moved boolean inputs as last parameter in functions "projectVector" and "rotateHeading".
• Simplified heading.ino example.

imuFilter - 1.0.0

Originally released on Jun 3, 2021.
First version of modified mahony filter based on a quaternion. Uses arrays to represent vectors and the quaternion.
