# Software Environments
|
|
|
|
|
|
|
|
This page details the various software environments available for use in CDC,
|
|
|
|
where the primary aim is to support development using GNU Radio. It describes
|
|
|
|
how to access these environments outside of EDS12.
|
|

|
|
Please don't hesitate to contact me if you encounter any environment related
|
|
|

## FEIT GPU Desktop
|
|
|
|
|
|
|
|
The FEIT Desktop used on the lab computers in EDS12 is available to you outside
|
|
|
|
of workshop through myUniApps. To access the environment:
|
|
|
|
|
|
|
|
1. Open a browser and navigate to
|
|
|
|
[https://unimelb.cloud.com](https://unimelb.cloud.com)
|
|
|
|
2. Login with your university credentials
|
|
|
|
3. If you wish, install Citrix Workspace on your personal computer by
|
|
|
|
clicking *Detect Workspace*, otherwise click *Use web browser*
|
|
|
|
4. Navigate to *Desktops > All Desktops*
|
|
|
|
5. Open a session by selecting *FEIT GPU Desktop*
|
|
|
|
6. Login to Windows using your university credentials
|
|
|
|
|
|
|
|
Obviously, you will not be able to interface with the SDR hardware when
|
|
|
|
accessing the remote desktop, but you can still perform much of your software
|
|
|
|
development and debugging.
|
|
|
|
|
|
|
|
> **WARNING:** The FEIT GPU Desktop is **non-persistent** – locally saved data
|
|
|
|
> may be lost when you log out. Make sure to save any files you wish to keep to
|
|
|
|
> another location, e.g., your OneDrive account.

## Ubuntu VM
|
|
|
|
|
|
|
|
The main environment we will be using is an Ubuntu Linux virtual machine (VM) in
|
|
|
|
which we can run GNU Radio. This option will allow stable usage of the Nuand
|
|
|
|
bladeRF SDR hardware that will be the focus of the design project. Additionally,
|
|
|
|
extending GNU Radio functionality through the creation and compilation of C++
|
|
|
|
signal processing blocks is straightforward under Linux.
|
|
|
|
|
|
|
|
On the FEIT GPU Desktop, the Ubuntu Linux VM can be accessed as follows.
|
|
|
|
|
|
|
|
1. Start VirtualBox: *Start Menu > Oracle VM VitualBox > Oracle VM VirtualBox*
|
|
|
|
2. Select the *ELEN90089_2023* virtual machine
|
|
|
|
3. Click the start button to launch the virtual machine
|
|
|
|
4. Login to Ubuntu using the following credentials\
|
|
|
|
username: cdc\
|
|
|
|
password: sdr
|
|
|
|
|
|
|
|
To open Python or GRC, first open a bash shell by clicking on the Terminal icon
|
|
|
|
in the dock: . The Python interpreter can
|
|
|
|
then be launched at the command line.
|
|
|
|
```
|
|
|
|
$ python3
|
|
|
|
```
|
|
|
|
Similarly, GRC can be launched from the command line.
|
|
|
|
```
|
|
|
|
$ gnuradio-companion
|
|
|
|
```
|
|
|
|
|
|
|
|
## MATLAB / Simulink
|
|
|
|
|
|
|
|
A support package for accessing the Nuand bladeRF has been installed should you
|
|
|
|
want to access a device in MATLAB and/or Simulink. Make sure to launch
|
|
|
|
**MATLAB R2022b**. See the following pages for documentation on how to use
|
|
|
|
the bladeRF SDR in MATLAB/Simulink.
