LimeSuite Wrapper on Go (Driver for LimeSDR Devices)

Usage

So far I need to do all the comments for the methods (since go auto-generates the documentation). But while I do that, you can check the examples. The documentation is available at: https://godoc.org/github.com/myriadrf/limedrv

Examples

So far there is a functional WBFM Radio that uses SegDSP for demodulating. You can check it at _examples/limefm. To compile, just go to the folder and run:

go build

It will generate a limefm executable in the folder. It outputs the raw Float32 audio into stdout. For example, you can listen to the radio by using ffplay:

./limefm -antenna LNAL -centerFrequency 106300000 -channel 0 -gain 0.5 -outputRate 48000 | ffplay -f f32le -ar 48k -ac 1 -

There is also a FFT Generator in fftaverage folder. The parameters need to be set in the code, but it does generate a nice JPEG with the FFT.

Static Linking

Since libLimeSuite doesn't generate static libraries by default (see https://github.com/myriadrf/LimeSuite/issues/241), you should manually compile it to provide the libLimeSuite.a thats needed for static linking.

You can just do the normal LimeSuite build with -DBUILD_SHARED_LIBS=OFF to statically build LimeSuite (that does not break current dynamic linked stuff)

# Assumes in libLimeSuite folder
cmake .. -DBUILD_SHARED_LIBS=OFF
make -j8
sudo make install

Then you can change the limewrap.go line with the linking definition from:

#cgo LDFLAGS: -lLimeSuite

to

#cgo LDFLAGS: -l:libLimeSuite.a -l:libstdc++.a -lm -lusb-1.0

And then compile normally your application. The libLimeSuite should be embedded inside your executable.
