Magnetometer Calibration In Rust

We offer offline (batch) and online (streamed) calibration for magnetometer. See offline and online as examples.

Why use this package?

• rust/c/cpp/java support
• normalization of points to prevent large values in scatter matrix.
• downsampling to compute post calibration spherical coverage, and prevent oversampling of a specific areas
• field tested

To build the wrappers for forigen langauges use cargo make cpp_wrapper or cargo make java_wrapper.

For android you will need to define links in .cargo/config.toml:

[target.aarch64-linux-android]
linker = "path to aarch64-linux-androidXX-clang++"

[target.armv7-linux-androideabi]
linker = path to armv7a-linux-androideabiXX-clang++

After, compile with cargo make java_wrapper --target aarch64-linux-android
