## C bindings

The static library can be (re)built with `cargo build --release`. Then `libwave.a` will be located in `target/release`.
The header file `wave.h` is located in the crate root.

Cross-compile for a specific architecture, e.g. Cortex-M4: `cargo build --release --target=thumbv7em-none-eabi`

Cbindgen is used to (re)generate the header file `wave.h`.

```bash
cargo install --force cbindgen
cbindgen --config cbindgen.toml --crate wave --output wave.h
```
