#rust-airspy This library is a Rust wrapper around AirSpy SDR library.

Dependencies

Build libairspy

cd ~/Downloads
git clone https://github.com/airspy/host.git airspy
cd airspy/libairspy
mkdir build
cd build
cmake ../
make
sudo make install

Usage

Put this in your Cargo.toml:

[dependencies.airspy]
git = "https://github.com/cubehub/rust-airspy.git"

And this in your crate root:

extern crate airspy;

Examples

Connect AirSpy SDR to your computer and run the example:

cargo build --example airspyrx
./target/release/examples/airspyrx > /dev/null

This example program can be used to listen FM radio. Make sure demod and sox are installed. NB: On Mac OS X use play and on Linux use aplay. This pipeline plays FM radio at 103.4 MHz:

./target/release/examples/airspyrx 103.4 | demod --samplerate 2500000 --resamplerate 230400 --intype i16 --outtype i16 --bandwidth 100000 fm --deviation 75000 | play -t raw -r 230.4k -e signed-integer -b16 -c 1 -V1 -

For rust-airspy developers

Tool called rust-bindgen is used to generate Rust functions from C files.

Mac OS X:

echo export DYLD_LIBRARY_PATH=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/:$DYLD_LIBRARY_PATH >> ~/.profile

Build rust-bindgen

git clone https://github.com/crabtw/rust-bindgen.git
cd rust-bindgen
cargo build

Generate Rust bindings

./target/debug/bindgen -l airspy -match airspy.h -match airspy_commands.h -o ~/Development/rust-airspy/src/ffiairspy.rs ~/Downloads/airspy/libairspy/src/airspy.h

Notice that there are still things like uint32_t, uint8_t etc in just generated ffiairspy.rs file. Replace them manually using your text editor:

uint64_t -> u64
uint32_t -> u32
uint16_t -> u16
uint8_t  -> u8
