Pixelpulse is a powerful user interface for visualizing and manipulating signals while exploring systems attached to affordable analog interface devices, such as Analog Devices' ADALM1000 or the Nonolith Labs' CEE.

Fully cross-platform using the Qt5 graphics toolkit and OpenGL accelerated density-gradiated rendering, it provides a powerful and accessible tool for initial interactive explorations.

Intuitive click-and-drag interfaces make exploring system behaviors across a wide range of signal amplitudes, frequencies, or phases a trivial exercise. Just click once to source a constant voltage or current and see what happens. Choose a function (sawtooth, triangle, sinusoidal, square) - adjust parameters, and make waves.

Zoom in and out with your scroll wheel or multitouch gestures (on supported platforms). Hold "Shift" to for Y-axis zooming.

Click and drag the X axis to pan in time.

• OSX - Navigate to the releases and collect the latest pixelpulse2-bundled.dmg.zip package. The latest testing build is available from Travis-CI.
• Windows - For a testing build, download the dependency package and the latest binary build from appveyor. For an official release build, navigate to releases and collect the latest pixelpulse2-setup.exe.
• Linux - Either build from source (below) or navigate to the releases and collect the latest .deb or .tgz file for your architecture. Install or extract as appropriate.

To build from source on any platform, you need to install a C++ compiler toolchain, collect the build dependencies, setup your build environment, and compile the project.

If you have not built packages from source before, this is ill-advised.

• Install LibUSB.
• Install using your package manager - "libusb" on OSX Homebrew, "libusb-1.0-0-dev" on modern Debian/Ubuntu distributions, "libusb-devel" on Fedora/CentOS.
• Build from source using the appropriate branch if a version of LibUSB with HotPlug support for your platform is not available. (Windows, Debian Wheezy)
• Install Qt5.4.
• On most Linux Distributions, Qt5 is available in repositories. The complete list of packages required varies, but includes qt's support for declarative (qml) UI programming, qtquick, qtquick-window, qtquick-controls, and qtquick-layouts.
• Binary installers are available from the Qt project for most platforms.

To build / run on a generic POSIX platform

git clone --recursive https://github.com/signalspec/pixelpulse2
cd pixelpulse2
mkdir build
cd build
qmake -qt=qt5 ..
make

To build / install for Debian, from the pixelpulse2 directory:

dh_make -p pixelpulse2_0.8 -s -c blank --createorig
dpkg-buildpackage
sudo dpkg -i ../pixelpulse2_0.1-1_i386.deb

To build / run on Ubuntu 15.04, via shabaz on Farnell.

• Please note that you make encounter issues if you are running a version of Ubuntu lower than 15.04, because the version of QT in the repositories will likely be less than 5.4 (this also applies if you are running a Linux distribution that uses an older version of Ubuntu, for example Linux Mint 17.1, which uses Ubuntu 14.04.)

• Get ready

  sudo apt-get update

• Install libusb and libudev

  sudo apt-get install libusb-1.0-0-dev
  sudo apt-get install libudev-dev

• Download and install Qt5.4

  wget http://qtmirror.ics.com/pub/qtproject/development_releases/qt/5.4/5.4.0-rc/qt-opensource-linux-x64-5.4.0-rc.run
  chmod 755 qt-o*
  ./qt-opensource-linux-x64-5.4.0-rc.run

• Install a couple extra Qt modules

  sudo apt-get install qtdeclarative5-controls-plugin
  sudo apt-get install qtdeclarative5-quicklayouts-plugin
  sudo apt-get install qtdeclarative5-dev

• Change your default configuration file

  sudo su
  cd /usr/lib/x86_64-linux-gnu/qt-default/qtchooser
  ls -l
  rm default.conf
  ln -s ../../../../share/qtchooser/qt5-x86_64-linux-gnu.conf default.conf
  ls –l
  exit

• Make a new folder, clone the pixelpulse library into it from git, and build it!

  mkdir development
  cd development
  git clone --recursive https://github.com/signalspec/pixelpulse2
  cd pixelpulse2
  mkdir build
  cd build
  qmake ..
  make

• After it is finished building, Pixelpulse2 should be ready to use with your M1K

• Make sure your M1K is plugged into your computer. The onboard LED should light up when it is connected. You can double-check by typing lsusb. You should see something along the lines of ID 064b:784c Analog Devices, Inc. (White Mountain DSP)

• You should be ready to launch Pixelpulse2. First, go to the directory it was built in:

  cd ~/development/pixelpulse2/build

• Run Pixelpulse2 as root

  sudo ./pixelpulse2
