wave

A no-std no-alloc gesture recognition library for low resolution TOF-Sensors.

Showcase

Horizontal Swipes

swipes_horizontal.mp4

Vertical Swipes

swipes_vertical.mp4

Static Holds

static_hold.mp4

Tests

Std is enabled for tests, but currently there is a bug that prevents cargo from building them successfully.
(see: github.com/rust-lang/rust/issues/48665).

To work around this, argument --lib wave needs to be used explicitly:

cargo test --lib wave

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 in the build script to (re)generate the header file wave.h.

To do this manually in the cli, execute:

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