# RusTL-SDR
A pure Rust implementation of the RTL-SDR driver, for shits and giggles.
This is mostly an exercise in writing low-level driver code.
Unusable, and highly unlikely to ever become usable. But it's fun.
For real alternatives check out the original [librtlsdr](https://github.com/osmocom/rtl-sdr/) implementation or the high-level [rtlsdr_mt](https://github.com/kchmck/rtlsdr_mt.rs) Rust bindings.
## Usage
Install the crate in your `Cargo.toml`:
```toml
[dependencies]
rustl-sdr = "0.2"
```
Use in your code:
```rust
extern crate libusb;
extern crate rustl_sdr;
fn foo() {
let ctx = libusb::Context::new().unwrap();
rtlsdr = rustl_sdr::RtlSdr::new(&ctx);
rtlsdr.init();
rtlsdr.do_stuff();
}
```
## Dev
The usual:
```bash
$ cargo build
$ cargo test -- --nocapture
```
Since there isn't (?) any good USB device mocking setup, for tests to pass an RTL-SDR device must be connected.
## Design
Similarly to the original rtl-sdr driver, we use libusb via the `rusb` bindings as the main interface to issue commands to the rtl-sdr USB dongle.
