LEDSpicer, LED animation controller for Linux.

[MeduZaPaT]

New version 0.3.6 is now available, this version includes:

• New Rom detection system based on a data file (using Mame is not a good option on retropie)
• Added a new kind of plugin, Input plugins, three of them:
• Mame Connects to mame and reads the output events to light elements or groups on the layout
• Impulse Lights elements when a button is press
• Actions Allows the creation of interactive input, like when you insert a credit, the start will blink and stuff like that
• Added more debug modes
• Improved speed
• Lot more!

I left some demo videos on the facebook page: https://www.facebook.com/LEDSpicer-2393969390678210/

@MeduZaPaT Thanks! I understand that the mame output lights only work with the standard mame but not with any retroarch-based version (mame2003, mame2003-plus, mame2010), do they?

I was unable to test them, basically they need to support the OSD output via network, anyway I added another plugin that simulates this feature somehow.

How do we incorporate the input code?
Thanks in advance.

@nukeray
I have LEDspicer running. Everthing is setup using ledspicerd -e and -l. Not able to figure out how to LoadProfile command line test. More importantly though I would really like to know how to use the input code for MAME. I am running the latest version of SDLMAME not Retropie so OSD is working fine. Any help would be awesome!!

New Release of LEDSpicer is out, 0.3.9
this version includes:

• Improves Pulseaudio plugin render.
• New PulseAudio mode "Wave" (check video).
• Adds new actor plugin FileReader, this plugin allows the user to create frames on an XML file, right now only RGBA format, more coming soon.
• Lot of bug fixes.
• Code improvement.

This is awesome!

How difficult would it be to add support for the howler?

The software was written in C and the source is available on github already.
https://github.com/wolfwaretech/Howler-Arcade-Controller-Firmware

would love to be able to use the controller I have rather than have to buy a new one.

Keep up the good work.

I'm trying to install LEDSpicer using the latest Retropieimage on a Raspberry Pi.
I am at the part where it says
./configure CXXFLAGS='-s -O3' --prefix=/usr --sysconfdir=/etc
it goes all the way through it OK but right at the end I get
configure: error: tinyxml2 not found.
Now I can see you need version 6, but I can only get version 4, so I assume that is why I'm getting the error?
I can't figure out how to install version 6.
I've been looking all over the net for a solution for hours and I'm completely stuck.
My knowledge of Linux is pretty basic, so as detailed a response as possible would be much appreciated ;)
TIA

@Whoremoan
Sorted it with the help of MeduZaPaT.
I'm going to try to repeat what I did on my other Rpi to make sure I can replicate the fix and I'll document it and put it up here in case anyone else has the same issue I had.

[Whoremoan]

@Whoremoan
OK here is what I did

Install tinyxml2 version 4, which is the newest version available in the repos of the pre-built Retropie v4.5.1 image.
You need this as none of the other versions bellow seem to install the tinyxml2.pc file

sudo apt install libtinyxml2-dev

Now change the tinyxml2.pc file to match the version LEDSpicer is expecting

sudo nano /usr/lib/arm-linux-gnueabihf/pkgconfig/tinyxml2.pc

Change version to 6.2.0
Ctrl X and save changes

Now download and install version 6a of tinyxml2

wget http://ftp.de.debian.org/debian/pool/main/t/tinyxml2/libtinyxml2-6a_7.0.0+dfsg-1_armhf.deb
sudo dpkg -i libtinyxml2-6a_7.0.0+dfsg-1_armhf.deb

This version does not update the tinyxml.h file, so install the version bellow which will install an updated version of this.

git clone https://github.com/leethomason/tinyxml2
cd tinyxml2

Edit Makefile so that the lib files are installed in the directory LEDSpicer expects to see them.

sudo nano Makefile

Change
prefix = /usr/local
To
prefix = /usr

Change
libdir = $(prefix)/lib
To
libdir = $(prefix)/lib/arm-linux-gnueabihf

Ctrl X and save changes

Now install

make all
sudo make install
cd ..

Finally delete the old version 4 library files and you should be good start the Installing section on the LEDSpicer without errors

sudo rm /usr/lib/arm-linux-gnueabihf/libtinyxml2.so.4
sudo rm /usr/lib/arm-linux-gnueabihf/libtinyxml2.so.4.0.1

It is possible that not all of these steps are needed, but it's the process I went through to get it up and running and it only takes a couple of minutes to do all of this, so you might as well

@Whoremoan this is really good, thanks for the update!

I am having a problem with the command:

sudo service ledspicerd start

It responds with this error:

Job for ledspicerd.service failed because the control process exited with error code.
See "systemctl status ledspicerd.service" and "journalctl -xe"

When I view journalctl -xe this is the error I am greeted with:

It looks like I am missing the file with this directory

/usr/share/ledspicer/.xml

Thanks in advance.

[Whoremoan]

@12ale

Have you tried running ledspicerd -d
This should tell you if any of the .xml files are missing or if there is an error in the .xml files.

[MeduZaPaT]

@12ale you need to set the ledspicer.conf file, that error is maybe the missing colors file.
you can check the logs also like this:

cat /var/log/syslog | grep ledspicer

Use sudo if you get access denied.

@Whoremoan @MeduZaPaT

Part of the issue was the missing color files.
I still get this:

Job for ledspicerd.service failed because the control process exited with error code.
See "systemctl status ledspicerd.service" and "journalctl -xe"

When I run ledspicerd -d I get this message:

Program terminated by error: Missing attribute 'port' inside root

Thanks for the help.

Disregard the previous post. I was able to get everything to work.
Thank you for the help.

I was kind of giving up hope I would get my Howler working on my Pi3. Is there a retro pi image that I can download that will have everything set up? I'm really new to all of this, and I'm also dyslexic so the amount of reading I have to do is pretty daunting.

I'd love to find an image I can just put on my SD card and start going.

[MeduZaPaT]

@SigmaX what OS are you running in the Pi3 ?
