Boblight possible?

[alpini]

Hi Guys,

How to get Speedy configuration into my Pi ???
I saw his "How to compile" guide.
I have installed Pibob a while ago and everyting works fine, accept the colors could be better offcourse:-)

Do i have to delete the file of Naderb or does it automaticly overwrite it ?
Will it to clash with the file of Naderb.........
Thanks alot

Anyone.....
Come on guys....

I did go to:
To compile use this howto.
https://github.com/Speedy1985/boblightd ... to-compile

Did in ssh:
sudo apt-get install make gcc g++ git libboost-dev libtool
DONE

Then did:
cd ~

Did get in prompt:
[email protected]:~$

Then i did:
git clone git://github.com/Speedy1985/boblightd-for-raspberry.git

Did get:
[email protected]:~$ git clone git://github.com/Speedy1985/boblightd-for-raspberry.git
-bash: git: command not found

Beats me, i grow up with Windows guys
Please help
What do i have to do?

Pibob is working in Pi, boblight is nice .
Want to have Speedys configuration, sounds better they say !?

You did not start with
sudo initctl stop xbmc
sudo apt-get update
?

Hi,

did:
sudo initctl stop xbmc
sudo apt-get update

But still no luck after doing: cd ~

Please give me step by step the lines that i have to do in ssh
Realy dont know how to fix this problem.

cd ~
Did it bring you to your home dir?

any user can return immediately to its home directory by typing the following and then pressing the Enter key:
cd ~
This is easier than typing the full name of the user's home directory, for instance, /home/josephine in the case of a user named josephine. (And it is just one of the numerous shortcuts that help make the command line on Unix-like operating systems so easy to use.)

Hi I have some problems with boblight, maybe you can help me.
I ordered http://www.ebay.co.uk/itm/230873716903? ... 1497.l2649 this and as it says 0.02A in every led I calculated 1A for total. So I'm using 5V 1.2A power. I connected cables as it was instructed in https://dl.dropboxusercontent.com/u/688 ... tware.html, White - DAT - pin 19, Green - CLK - pin 23, Blue - GND - pin 6. And power to power cables. Other end of led strip is untouched. I have fresh raspbmc card and I compiled Speedys stuff as instructed in https://github.com/Speedy1985/boblightd ... to-compile. No problems there I suppose. Boblightd runs as expected but when I try to run boblight-constant 00ff00 nothing happens. Any ideas how to solve? I'm willing to try anything

My conf file is as follows. Maybe problem is in my conf file. At one point I got 3-4 light on from the other end, but not anymore. Can it make any difference that I'm running this on first revision raspberry with only 265Mb memory.

I haven't tried the movie yet, just constant light as i tought it would be nice to get lights working first. Should i try movie too? Is my conf file ok

try with my config file:

https://www.dropbox.com/s/xy423w6kj76ldwq/boblight.conf

Remember to change type to ws2801
and output to spidev0.0

Hi, i am now busy to mod the orginal xbmc-addon to PiBob
But on this moment there is a error in the code.
I will fix this error soon.

Did not work. I tried to flash raspbmc again and compiled again as described.

First led lights when I connect power. But I can not control even the color of that one led. If I tap the cables, led changes the color and flickers but does not stay in any color but light blue, nearly white.

Is there any difference which end of the cables I connect to raspberry? And only one end should be connected, right?

boblightd is running and displays setup succeeded when I start it. And boblight-constant says connection opened when I run it, and that is the last line and then it stays there until I stop it by pressing ctrl+c.

Any ideas, is there a way to light all led with out raspberry, should they light when power is connected.

actually it's the last led that lights, not the first

[NietGiftig]

Yes there is a difference each cable has an data in and a data out side (SDI and SCL).
The + and ground are on both sides the same.

Witch side and witch colors you have to find via your reseller or if that is not possible, Google is your friend

Connector wires: White- DAT, Green-CLK, Blue- GND

Naked wires: Red- power supply "+"5V , Blue- power supply "-"(GND) 5V

Input: female side(IC side)

Apparently I did not read that too carefully and missed the input side
So I have to try another end tomorrow, I think I chose the wrong side

And the video works fine. Great.

Any idea is it possible to get leds working with stand alone bluray player. I mean getting hdmi or some other signal in to the raspberry and using the leds while passing the signal out from hdmi to amplifier. Something like that, grab display signal and use i to control leds while other, more powerful player plays the actual video from bluray

hello, i've been trying to follow these guides and i'm stuck.

i have a raspberry pi and 4 strings of 25 ws2801's. i first tried nadnerb's guide https://dl.dropboxusercontent.com/u/688 ... tware.html and it all seems to go fine except nothing happens. i'm fairly certain i've got the wiring correct as it matches http://learn.adafruit.com/system/assets ... 1344878827 and these are mine http://www.insomnia.org/led/documentati ... s2801.html. i've got the clock, data and ground wires attached to the pi and the 5v and ground attached to a 5v adaptor. When i say nothing happens, i can start the boblight daemon and send the "turn all to green" command and the pi reports success through SSH but no lights come on. Actually i see similar to what russako reported with regard to only the last led coming on when i move the string around and this lead me to investigate whether i had the led's wired back to front. i think initially i did have them the wrong way round, i assumed a female connector indicated the input on the led's but closer inspection of the led shows IN and OUT printed on either side of the led plus the controller chip is on the side marked IN. I now think the male connector is the input end of the leds. however even trying the other way around resulted in nothing. i'm using the boblight.conf that nadnerb provides plus 2 of my led strings

i then tried speedy's new build which also doesn't work. it compiles fine and i can start the boblight daemon but when i try to send the command to turn all to green i see repeated messages of which the most useful indicator is something that says SO_ERROR and "broken pipe". i can't find much else around the web that helps me further than this. i'm using the boblight.conf downloaded from nadnerb's dropbox again as it seems like this should work and placed it in the etc folder

I've tried both builds twice and switched the wiring of the lights around in between so i think i've tried all options in terms of physical config. unfortunately i'm a linux noob, although possessing reasonable common sense when it comes to computing, so my investigations on the software side are limited to information i can source from elsewhere.

i would really appreciate any help or direction anyone can provide?

thanks!

[spaceboy]

hello again, so i fixed 2 mistakes. i read speedy's final instruction again and then realised that my lights aren't the ones i linked to so they were connected wrong. i am pretty certain they are correct now but when i send the constant command just the first light comes on. it turns off when i control+c but no other lights come on. feels like i'm close but i can't see what else is wrong, anyone any pointers?

thanks

Hi

I've managed to get boblight working on my raspberry pi with video/movies, even youtube videos via the youtube addon. However I have a slight issue that when streaming live tv from tvheadend i get no lights. Also found that if i try to change channel XBMC restarts. Just to give a bit more detail of what i have setup, I've followed the following instructions for my setup.

I have 100xWS2801 LEDS

http://pibob.nadnerb.co.uk/software.html#part1

but used the source for boblight from here - https://code.google.com/p/boblight/wiki ... spberry_Pi

Also used https://www.dropbox.com/s/uyw6u829cb9ut ... 514.tar.gz this copy for the omxplayer.

So as i said all works just not working from a tvheadend tv stream and also the crashing of xbmc.

I've got this log capture which you can see i can watch a recorded TV video fine (springwatch), then I start watching live tv channel (BBC1) i then change channel to BBC2 and thats when XBMC reboots.

I know an odd one but i'm thinking its something to do with the OMXplayer as first port of call ?

Thank you for any help on this one.

Hi,

After lots of research I did not find solution to my problem with flickering LEDs.

Here is my setup:
ubuntu(13.04)->xbmc(12.2)->boblight addon
raspberry->boblightd->SPI->leds(100x ws2801)

boblight on ubuntu was compiled with :

Code: Select all

./configure --without-portaudio --without-opengl --without-x11 --prefix=/usr

boblight on raspberry was compiled with :

Code: Select all

./configure --without-portaudio --without-opengl --without-x11 --without-libusb 

xbmc boblight addon conf :

Code: Select all

speed = 50
autospeed = 25
interpolation on
saturation = 1.10
value = 1.50
threshold = 20

boblight conf :

Code: Select all

I tried several configurations but leds are still flickering.
Even with boblight-constant or VZoltan's php

Is that someone could help me?

Can you post A video of your flickering?

Check that you have a good common ground for the LEDs and the pi.

The data and clock wire are very sensible to interference check that they have a good connection and are isolated properly...

In some bad quality LEDs there are soldering residue that cause flickering on some LEDs I had this on 1 out of my 100 LEDs.

[plng]

Well...

You were right.

I checked (move up side down) every wires at rear of each led, when arrived to 97th the last 2 led were shutdown.
Then it was impossible to control the leds, then I lost my ssh connection.

When I plug the power the power led light up and that's all..
I took the pi out of his box to check it, the proc heats very quickly and very hard and nothing else happens...

My pi is dead

Edit :

My sd card also died...

Well... F*ck you too electronics's god !

...unfortunately, I also have the same experience. Led strip should reverse the connection wires (+ black and - red), but the power wires correctly. I have not checked it, it was raspberry polarity and is destroyed
