`wavegen` is a wavefrom generator made with
## How to use it?
1) Add `wavegen` to your project:
```toml
[dependencies]
wavegen = "0.4"
```
Or, to use the *no_std* version (custom global allocator is required):
```toml
[dependencies]
wavegen = { version = "0.4", default-features = false, features = ["libm"] }
```
2) Define a waveform with sampling frequency and function components:
```rust
let waveform = wf!(f64, 200., sine!(frequency: 100., amplitude: 10.), dc_bias!(20.));
```
3) Turn it into an iterator and sample:
```rust
let some_samples: Vec = waveform.iter().take(200).collect();
```
Refer to [documentation](https://docs.rs/wavegen) for more exhaustive usage examples.
## Show me some examples!
### Interactive demo
Check out the demo at https://wavegen-demo.netlify.app
### Plot charts
* Simple sine
* Two superposed phase-shifted sines
* "Real life" example: 300Hz sine signal with 50Hz interference noise
* Sawtooth
* Superposition of sine + sawtooth
* Square wave
* Superposition of Sine, Square and Sawtooth with different frequencies
All above examples are generated with simple program found in `examples/plot.rs`. Run `cargo run --example plot` to generate them yourself.
## MSRV
The *Minimum Supported Rust Version* is `1.60`.
## Similar crates
* [Waver](https://github.com/amrali/waver/) which was the inspiration for this crate
## Breaking changes
### 0.2
- Braking change in how macros are annotated, changing the annotation form from `frequency = n` to `frequency: n`
### 0.4
- `Waveform::get_sample_rate` renamed to `Waveform::sample_rate` and now returns a borrowed values, as per rust API specs.
- `Waveform::get_components_len` removed. The functionality can be achieved by a new getter `Waveform::components`.
