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.
print(radio);
# --- Getting a buffer from the radio
sig = recv(radio,nbSamples);
# This also can be done with pre-allocation
buffer = zeros(Complex{Cfloat},nbSamples);
recv!(buffer,radio);
# --- Release the radio ressources
close(radio);
# --- Output to signal
return sig;
end
The package can be installed with the Julia package manager.
