    hi, how could i use processing to control rainbowduino v3.
    Pixelcontroller seems to use pure data?

    neorainbow is only aivalaible for v1 of rainbowduino ?

    Tried to get the PixelController working with an Arduino UNO and a Teensy ++ 2.0 on MacOSX 10.9… Neither device did work: I’ve uploaded the FW-sketch to my Teensy / Arduino and my LED Matrix cycles the rainbow pattern – so I guess on the Teensy / Arduino side there is no problem. What am I doing wrong? What should I change in the config.properties-file to get this working? What settings should I write there for Teensy ++ 2.0 device (e.g. my Teensy-port: /dev/tty.usbmodem12341) ? Thanks in advanced.

    Thank you! I’ve checked that. Now I can see that PixelController uses the right port, but as soon as I open the PixelController Tool, my LED Matrix stops working (freeze). Also, PixelController stops playing the animation…

    Ok. Now everything is working fine… Had to change the FW for the Teensy 2.0 ++… Thank michu. Keep up the great work!!!

    I try pixelControler v1.5.
    The pattern came about 5 ou 6 seconds after the progarmm begin to run. then i got 10 to 20 frames (images) and the matrix freeze but the programm still running (speed : 5fps).

    I look at the log file and have a lot of : “spain.rv3sf.api.RainbowduinoV3 waitForACK
    WARNING: No serial ACK reply received for frame fragment 0 after waiting for 50ms. Serial port has only 0 bytes available.”

    I try also to use processing (with the programmer’s pain program) and have and error mesage like this : Unable to send frame since the serialPort isn’t initialized!

    I think the problem is about the com port so…
    Question : how to initialize the port com. (COM6 for me) :-))

    Thanks a lot, i hope to succeed to use the pixel controller and my rainbowduino for my project..

    Thanks again

    long waited for my china-led to try your pixel-controller on my long waited iboards from china. suprisingly my leds are ws2811 instead of ws2801. so i have only date-line without clock. is it an worth the effort to get ws2811 running with your pixelcontroller? do you have expereient with such led-strips? thanx a lot for your time a answer. still looking forward to get it running.. all seems so impressive here ….

    i investigated in the pixelcontroller.readme on github. i hope to get my ws2811 leds running, but i dont see how the firmware for the arduino an the library on the arduino go together. you mentioned in the readme: ” for other panels (WS2801, WS281x…) install the integration/ArduinoFw/libraries/FastSPI_LED2 library.”. but how is the controlling-chain going from pixelcontroller to the stips going? pixelcontroller-usb/net-arduino with firmware (which?) and a library?. At the moment i cant see, how library and firmware are put together, so that pixelcontroller can control the pixels. any hints? thanx a lot for all the work, looks verry promising, pity i got ws2811 instead 2801. else i would be up an running with pixelcontroler at this minute… ;-)

    hey michu,
    thanx a lot. for great pixelcontroller. with my ws2811 i tried fo get an arduino uno r3 running as an art-net client. worked in 5 min from here: http://www.deskontrol.net/blog/arduino-based-artnet-node-for-led-pixels/ (but had to work out to connect ground near data-line to arduino to get it working).

    your tip to get a ws2811 running is the “TPM2-Firmware”, like linked from your github-readme: “Teensy with TPM2 firmware using fastspi2 lib]——[LED#1].
    Right? i will give it a try…

    and by the way: seems there is a bug in “color-scroll” with effect “rotate 90″ on my 8×13 matix. can you confirm this?

    great work, again. thanx a lot, go on further!!

    hi michu,
    if it is a bug, it is still present in 1.5.1.
    i made an git-hub issue out of this. (first try for me). is it the right place for bugs?
    i also put there a screenshot of this “bug” an for a ‘feature-request’.

    to send commands to pixel-controller from plain bash to a port would be wonderfull (socat, nc, telnet, mpd-alike… — as wonderfull as there would be a configure option for a timeout to change the random visualisations instead of beat-only …

    all here: https://github.com/neophob/PixelController/issues/43
    and issue 44+45

    live-painting on matrix.

    hey, phantastic! i tried the screen-capture mode and captured a bitmap-painting-app. so i had live-painting on our led-matrix. great, great, great!

    may you will put this use of the screen-capture also in the readme for others?
    graet feature…

    greets, tozett

    i add my experience here. ok? (or on github?)

    is there a way to run the pixelcontroller headless? just a controller for one or more ledmatrix? i would change modes only with cmd line (OSC…)

    thanx, ozett

    ok. i test your beta, if you like.
    drop me a email, if it is online. Or shoudl i subscribe your blog?

    wonderful work, once again. …!

    Performance needed?
    i tried today running it on an raspberry pi with oracle-java in raspbian.
    it worked, but i got updates with pause within. a veeeery poor framerate…

    as it run on my windows dualcore machine, it was smooth.
    will the head-less version run smooth on rasberry? or is it without reach?

    Performance Platforms..just to compare my last post:

    the raspberry b-model had (raspian) with xrdp and:
    Processor : ARMv6-compatible processor rev 7 (v6l)
    BogoMIPS : 697.95

    and now i run Pixelcontroller on fluxbox-remote desktop with xrdp (ubuntu10.04,default-java) on an intel-mini-itx with an atom,
    which has (an old? atom):
    model name : Intel(R) Atom(TM) CPU D510 @ 1.66GHz
    bogomips : 3333.41

    it is fluid again …

    hey michu,
    i found the 200rc1-Version. And tried it just a minute ago on my rasperry. With Gui, still poor framrates. With your new headless-Version via cmd-line i had _very good_ framerates of 21 on my rasperry with normal cpu-settings. Gloroius! Thanx. I than tried medium-overclock to 900 MHz, just to see a difference. I will report…

    Now i am (personally, forgive me ;-)) only missing linux/bash cmd-line control to switch some basic settings/presets (without doing it from a native java-cmdline). didnt figured out how to do this via OSC. (Google gave my Python sceletion so send art-net messages from bash. Not soo poor…)

    I found stated in the readme the fix for sorting image-dropdown. Still Generator and effect-Dropdown somehow unsorted?

    The Textoptions are limited to two? Both are running Text? Even with Generator-Speed to Zero, Text ist Ping-Pong’ing. What about an option to display static Text, just to have an (easy) Character Display. And not to use images instead.

    If I Activate Random-Preset Mode in gui, what about showing name of the actual Preset below the Visual? I would have to switch to preset-Page to control the random choosen preset…

    Great Work, and a fast move from 1.5 to 2.x…!!! Great!
