If you don’t know what Julia is (and don’t want to know)

Julia is a fast and powerful programming language made for scientific and numerical computing. But if you just want to try out TempestSDR without learning to code — this guide is for you.

What you’ll do

  1. Install Julia
  2. Install TempestSDR
  3. Run the app

1. Install Julia

Recommended: JuliaUp

  • Go to: https://github.com/JuliaLang/juliaup
  • Click “Download” and install JuliaUp.
  • Follow the on-screen instructions.

Manual method

  • Go to: https://julialang.org/downloads/
  • Download the correct installer for your system (Windows / macOS / Linux).
  • Install it like any normal program.

2. Install TempestSDR (only once)

We now have to install the package. If you are familiar with pip from Python, this is a similar approach with the following command 

julia import Pkg
julia> Pkg.add("TempestSDR")

This may take a while ! Be patient, take a coffee and wait until the end of the installation

3. Use TempestSDR

You can now use TempestSD. This require 3 steps

  • Open Julia (i.e Open a terminal (or PowerShell on Windows) and type julia)
  • In Julia type 
using TempestSDR
  • Then call the method based on what you want to do (see the cod the for arguments)

TempestSDR.gui(;sdr=:bladerf,carrierFreq=600e6,samplingRate=20e6, gain = 30,addr="usb:1.7.5")`

Note

  • By using this steps, the package is installed in your global environment : You can instal it into an isolated env (see https://pkgdocs.julialang.org/v1/). If you are not plan to use Julia a lot, global env is fine.
