This package proposes some bindings to UHD, the C driver of the Universal Software Radio Peripheral USRP

The package is heavily dependent on libUHD the open source driver from Ettus research. The library is shipped in the package through Artifacts, and the current implementation uses libUHD.4.0.0

The purpose is to able to instantiate the radio peripheral inside a Julia session and to be able to send and receive complex samples directly within a Julia session.

For instance, in order to get 4096 samples at 868MHz with a instantaneous bandwidth of 16MHz, with a 30dB Rx Gain, the following Julia code will do the trick and returns a vector with type Complex{Cfloat} with 4096 samples.

function main()
	# ---------------------------------------------------- 
	# --- Physical layer and RF parameters 
	# ---------------------------------------------------- 

	carrierFreq		= 868e6;	# --- The carrier frequency 	
	samplingRate		= 16e6;         # --- Targeted bandwdith 
	rxGain			= 30.0;         # --- Rx gain 
	nbSamples		= 4096;         # --- Desired number of samples

	# ---------------------------------------------------- 
	# --- Getting all system with function calls  
	# ---------------------------------------------------- 
	# --- Creating the radio ressource 
	radio	= openUHD(carrierFreq,samplingRate,rxGain);
	# --- Display the current radio configuration
	# Both Tx and Rx sides.
	# --- Getting a buffer from the radio 
	sig	= recv(radio,nbSamples);
	# This also can be done with pre-allocation 
	buffer = zeros(Complex{Cfloat},nbSamples);
	# --- Release the radio ressources
	# --- Output to signal 
	return sig;


The package can be installed with the Julia package manager. From the Julia REPL, type ] to enter the Pkg REPL mode and run:

pkg> add UHDBindings 

Or, equivalently, via the Pkg API:

julia> import Pkg; Pkg.add("UHDBindings")
