SoapySDR provides a hardware abstraction layer for many software defined radio devices.

API Documentation | Changelog

This library requires dependencies not handled by Cargo:

• libsoapysdr 0.6, 0.7, or 0.8
• libclang 5.0+ (for bindgen)
• pkg-config

(Tested on Ubuntu 22.04)

sudo apt install libsoapysdr-dev libclang-dev llvm-dev pkg-config

# Choose the appropriate drivers for your hardware:
sudo apt install soapysdr-module-rtlsdr soapysdr-module-hackrf soapysdr-module-uhd soapysdr-module-lms7

nix-shell

(see shell.nix)

Install pre-built PothosSDR and LLVM, then

• Set LIBCLANG_PATH environment variable to LLVM bin directory for rust-bindgen
• Add PothosSDR bin directory to system PATH

Many SoapySDR driver modules have error handling and thread safety bugs. This library provides safe Rust wrappers assuming the drivers meet the (under-documented) intentions of the SoapySDR core API contract, but if SoapySDR loads modules that violate this contract and you do atypical things with them, you may encounter unexpected behavior. For details, see this SoapySDR issue.

This crate comes with two small utilities that serve as example code.

Displays device details like SoapySDRUtil.

cargo run --release --features=binaries --bin soapy-sdr-info

Records data from a device.

e.g. capture 15 seconds of data from the FM band:

cargo run --release --features=binaries --bin soapy-sdr-stream -- -d driver=rtlsdr -r out.cfile -f 96M -s 1M -n 15M

The resulting file contains 32-bit little-endian complex float samples, and can be opened with inspectrum.
