PixelController Changelog

What's new in PixelController 2.1.0 RC 1

Apr 3, 2014
  • Add client/server architecture. PixelController can started headless on a server, connect to the server with the client GUI (same look as the standalone version)
  • Add RaspberryPi WS2801 output driver
  • Add custom led matrix mapping tool, see http://pixelinvaders.ch/pixelcontroller/ for more details
  • Add Bonjour/Zeroconf support, PixelController register itself as "pixelcontroller.local"
  • Add new ROTATE_ Generator/Effect/Mixer/Colorset OSC command
  • Add Noise generator
  • Add Gamma 3.0 color correction
  • Add TouchOsc layout for phone and tablet
  • Add simple performance test (PixelController.sh -perf or PixelControllerRPi.sh -perf)
  • Add Random Mode with selectable time-life (option randommode.lifetime.in.s) (Issue #44)
  • Add more Blinkenlights movie files
  • Add new effect Posterize
  • Add new effect Darken
  • Add PixelInvaders firmware for Arduino UNO, thanks Yves Alter. This should fix all UNO related issues.
  • Add new output rotate option: FLIPPEDY
  • Remove support for stealth panels
  • Fix decouple fps setting of PixelController from the GUI update speed (Issue #61)
  • Fix replace Pixel and Quality image resize code with custom implementations (nearest neighbour and bilinear), major performance improvement
  • Fix add missing float parameter to the OSC server, only int values were parsed
  • Fix the framerate configuration can be a float number (ex. fps=0.1) if you need a really slow update rate
  • Fix refresh GUI settings when random mode kicks in
  • Fix generator speed changes the target fps (0..200%), much smoother (Issue #46, #52 and #59)
  • Fix generator speed and brightness were not stored as part of the preset (Issue #62)
  • Fix capture generator, crashed if recording window was too small
  • Fix Metaball generator resolution for different sizes
  • Fix more code cleanup
  • Fix optimize CPU usage in heavy beat detection mode
  • Fix optimize preset load time, load resource files (image and blinkenlight) only if generator is used in preset
  • Fix reduce rotozoom effect speed
  • Fix visual size in GUI
  • Fix rename preset.led -> preset.properties, all PixelController extension files have now the same file extension.
  • Fix update build process, put RPi specifiy resources (Serial and pi4j) dependencies into special directory, do not include junit dependencies.
  • Fix speedup Blinkenlight parser, some frames were displayed too long
  • Fix Multliply and Negative Multiply mixer, output didn't respect ColorSets correctly
  • Fix Subsat mixer - was completly broken
  • Fix output layout for all *FLIPPEDY entries - all FLIPPEDY action were broken.

  • Add new command line version of PixelController - run on a headless server (like an RPi)
  • Add make speed of generators configurable via GUI and save it as part of the preset (Issue #46)
  • Add Beat Workmode, define how beat input should be interpreted. Options: Linear, Moderate Sound and Heavy Sound
  • Fix Update GUI much faster (instant feedback)
  • Fix GUI, sort images and blinkenlights file dropdown content case insensitive
  • Fix remove obsolete config options (initial.image.simple, initial.blinken, initial.text) but load a preset during startup
  • Fix rename config options (maximal.debug.window.xsize -> gui.window.maximal.width, update.generators.by.sound -> sound.analyze.input)
  • Fix typo, rename data/presents.led -> data/presets.led
  • Fix respect maximal window size defined in the config file
  • Fix adjust matrix simulation window for large resolutions
  • Fix effect Rotate90 - works now for non-square resolutions
  • Fix improve error reporting
  • Much faster startup time
  • Display gamma correction on output matrix
  • Removed TCP Server, used by the old PureData frontend and CLI client
  • Update documentation, see readme.pdf
