Visualizing the frequency spectrum.

Frequensea

Frequensea is an open-source toolkit for visualizing the electromagnetic spectrum.

Watch the Frequensea video introduction.

Features

• Fast core written in C, with Lua scripting on top.
• Support for RTL-SDR and HackRF devices.
• Support for Oculus Rift for viewing the spectrum in virtual reality.
• Support for OSC to communicate with other applications or devices.
• Basic building blocks for sampling, filtering and visualizing RF data.

Installing dependencies (OS X)

brew update
brew install cmake glew fftw librtlsdr hackrf libpng libsndfile pkgconfig homebrew/versions/glfw3

Installing dependencies (Ubuntu 14.04 LTS)

sudo apt-get install -y git cmake gcc g++ make libfftw3-dev libpng-dev libusb-1.0.0-dev pkg-config xorg-dev libglu1-mesa-dev libopenal-dev libglew-dev libhackrf-dev librtlsdr-dev pkg-config

# There is no GLFW3 package so install from source
wget https://github.com/glfw/glfw/releases/download/3.1.1/glfw-3.1.1.zip
unzip 3.1.1.zip
cd glfw-3.1.1
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

Installing dependencies (Raspberry Pi - Raspbian Jessie)

sudo apt-get install -y git cmake gcc g++ make libfftw3-dev libpng-dev libusb-1.0.0-dev pkg-config xorg-dev libglu1-mesa-dev libopenal-dev libglew-dev libhackrf-dev librtlsdr-dev libglfw3-dev

# Raspberry Pi doesn't support GLX, so until that's supported,
# we'll use the software rendering packages.
# Note that I found that installing mesa can *remove* libglfw3-dev,
# which we need, so if you get errors against that make sure
# it's installed.
sudo apt-get install -y libgl1-mesa-swx11 libglu1-mesa-dev libglew-dev

# Disable default kernel driver
sudo modprobe -r dvb_usb_rtl28xxu

Note that you might need to run as root to claim the graphics driver, especially if you don't use the default "pi" user.

Building

mkdir build
cd build/
cmake ..
make

Running

./frequensea ../lua/static.lua

With the Oculus:

./frequensea --vr ../lua/static.lua

Save the output to a PNG sequence:

./frequensea --capture ../lua/animate-camera.lua

Build and Run

make && ./frequensea ../lua/static.lua

Documentation

• API.md contains all available Frequensea calls.
• Examples are in the "lua" folder.

GLFW ERROR 65544: focusing a windows requires user interaction

Hi,

I just compiled frequensea from Git and build it. When I start it I get an error.

./frequensea ../lua/static.lua

This is GLFW telling me that it cannot focus the window. I can see it flip in and out for a split second.
https://github.com/glfw/glfw/blob/master/src/wl_window.c#L616 I don't know why it steps out here.

My system:

• Arch Linux, AUR build https://aur.archlinux.org/packages/frequensea-git/
• Linux 4.6.4-1-ARCH Kernel
• wayland 1.11.0-1

weston --version
weston 1.11.0

I just started weston and wanted to see the sample to get into it.

Segfaults on Linux

I have managed to build latest frequensea on Arch Linux x64 without noticeable problems, but it segfaults upon running:

> frequensea ../lua/static.lua 
OpenGL Renderer: Mesa DRI Intel(R) Ivybridge Mobile 
OpenGL Version: 3.3 (Core Profile) Mesa 12.0.1
Segmentation fault (core dumped)

These are versions of my runtime-related libraries:

• glew 2.0.0
• glfw-x11 3.2.1
• fftw 3.3.5
• libpng 1.6.24
• openal 1.17.2
• libusb 1.0.20-1
• glu 9.0.0
• openal 1.17.2
• glew 2.0.0

What additional info can I provide/how should this be debugged?

Build errors on Ubuntu 22.04

I'm running Ubuntu 22.04 in a virtual machine on a windows host. I am using X11 instead of Wayland, though I've tried both.
I've made sure to install the latest GLFW (3.3.7) and I took out "-Wall -Werror -pedantic" from line 4 of CMakeLists.txt. When I follow the instructions from the README, "make" has the following errors:

I noticed that this was similar to some other open issues, but not exactly the same.
Any help is appreciated.
This is a fascinating app I really want to try. :)

Processing Port?

Is there any possibility of porting this project [or parts of it] into a Processing library?
Would any of Frequensea's features be able to run in a Processing environment?

It's a fantastic application!

Raspbian Jessie build error

I'm getting the below when building Frequensea on Raspbian Jessie. I was initially getting build issues prior to that, but realised that libhackrf-dev wasn't listed as a dependency under the Raspberry Pi section, this allowed me to get this far.

Completion of error handling

Would you like to add more error handling for return values from functions like the following?

• fopen ⇒ main
• printf ⇒ receive_sample_block

Can someone compile this wonderful application into Windows 10 compatible software with installer?

The original app developer does not have time resources to do that.
