Fusion Brain program for Linux

malcom2073 · 02-16-2009, 05:50 PM

Here is a library I have written to allow Fusion Brain V4 access in Linux. I have not added support for previous versions, however I will soon. This library depends on libusb-0.1 which can be installed through most distros' package management utility. (yum install libusb-devel on fedora, or apt-get install libusb-dev on debian). The ./FB program included in this package was compiled on ubuntu, so it may or may not work on other distros of linux. The source code is also included so people who cannot run the program can attempt to compile it themselves

You will need libqt4-dev (on ubuntu) to compile this program, and then it is just a matter of "qmake && make" to compile it.

Edit 2/28/2009: Update attached, gui program by Qt. You will need libqt4-dev to compile it, and then just run 'qmake && make' to compile. I have attached an executable, but I don't know how well that will work. I have removed the command line app, that didn't seem to get any interest.

So where is this program?

malcom2073 · 02-21-2009, 11:10 PM

Uh, it WAS linked..... wait a few

Edit: Main post has the link now. 'bout time someone mentioned I forgot something!

Hey malcom its good too see you have already made progress on this, ill download it soon and test it out.

The ./main program included in this package was compiled in ubuntu, so it may or may not work on other distros of linux. The source code is also included so people who cannot run the program can attempt to compile it themselves

Command line for compiling on ubuntu:
g++ main.cpp fblib.cpp -o main `pkg-config libusb --libs --cflags`

If you run the program from the command line with no arguments, it will print out a list of examples for how to use the program. Currently only the ability to turn digital outputs on and off, and read analog input is supported. I am working on supporting more, such as timers and pwm. If anyone who has a fusion brain and knows how to run linux, can you please test this out? I am working on a GUI interface that can either be picked apart, or embedded into Linux frontends. Nghost will soon have plugin support for the Fusion Brain as well via this library.

Edit: I never even noticed the error message saying it didn't upload. Why didn't someone mention something! arg!

Is it possible for you to write a comedi driver for this device? http://www.comedi.org/
This hardware looks like it would be perfect for some small robotics projects. http://www.orocos.org/

I'm sure its quite possible to adapt it to that, but that's not really useful for most carpc applications which is what this was intended for. You can feel free to use the code and adapt it to comedi (under GPL of course)

I've edited the original post due to the fact that I rewrote the library to use libusb0.1 rather than libusb1.0. Most distros have a 0.1 binary package, making it much easier for people to compile

haha I work with comedi and orocos on a daily basis

would be sweet to set this up!

I could do it using your code as a example. It looks like the register level bits are defined clearly. I've coded a pcmcia card in the comedi driver lib already and this device is pretty simple. I guess I'll have to buy a few cards for work as product examples and use one to test code with.

PS. I work for Microchip at the fab in Oregon. We make a lot of PIC18F wafers.

We could certainly set you up. Email us at fusioncontrolcentre@gmail.com

Nice work getting this far!

Can you please post up the command line app & source?
osx has libusb 0.1.12 and I'd like to have a go at compiling under Darwin.

Thanks.

Using malcom2073's lib, I created a simple daemon that exposes a DBus interface to the fusion brain.

This should (IMHO), be used in place of direct access to the library for most applications. DBus's IPC allows you to code in any language that has DBus bindings: Python, C++, C, C#, Java, Ruby, etc, etc, etc rather than just pure C++ which is what the library is written in.

This is developed for the OpenICE platform under the GPL license.

To install, run qmake, make. Copy FusionBrain.conf to /etc/dbus-1/system.d/. Run as root.

See fbddbus.xml for information on the DBus methods and signals available.

Have fun!

I do not have Fusion Brain, but still... SWEEEEEEEEETES!

Fantastic work guys!

As soon as I learned about the Fusion Brain I ordered one and it arrived today. I couldn't resist giving it a whirl so I downloaded/built Malcom's FB package and giggled like a little schoolgirl as I toggled LEDs

I then downloaded/built Kev's fbd and ran it per the instructions above. I know next to nothing about dbus so figured a quick commandline test was a good start, but I ran into problems. It's past my bedtime (I'm getting old) so I figured I'd ask in case there was a quick answer. Using dbus-send, I'm not sure how to toggle one of the digital outputs. I have #1 turned on right now so I tried to turn it off with

cgalpin@jaunty:~/fbd$ dbus-send --session --print-reply --dest="org.openice.fbd" /org/openice/fbd org.openice.fbd.fusionbrain.SetSingleOutput int16:1 boolean:false
Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.openice.fbd was not provided by any .service files
cgalpin@jaunty:~/fbd$ dbus-send --session --print-reply --dest="org.openice.fbd.fusionbrain" /org/openice/fbd org.openice.fbd.fusionbrain.SetSingleOutput int16:1 boolean:false
Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.openice.fbd.fusionbrain was not provided by any .service files

As you can see, it doesn't seem to understand the destinations. Any ideas? I tried a few other things and perhaps made progress with

cgalpin@jaunty:~/fbd$ dbus-send --system --print-reply --dest="org.openice.fbd" /org/openice/fbd org.openice.fbd.fusionbrain.SetSingleOutput int16:1 boolean:false
Error org.freedesktop.DBus.Error.UnknownMethod: No such method 'SetSingleOutput' in interface 'org.openice.fbd.fusionbrain' at object path '/org/openice/fbd' (signature 'nb')

Also, I first build FB using libusb-1.0-0 since it was newer, and other than a #include and a makefile tweak it built and ran fine. When I went to build fbd, there were a boatload of differences to both FB, but also the version of usb. I started making the changes from usb to libusb but then started finding functions that didn't seem to have libusb analogs and gave up and just installed libusb-0.1-4 and libusb-dev and it built fine unmodified. In a nutshell, what is the difference between these versions?

Anyway, just wanted to say thanks and I look forward to being able to get this working, and take some time to contribute myself.

I would use (and do use) a utility like qdbusviewer to test fbd. You can use it to browse the system bus to find the org.openice.fbd service and even test out the different functions. If it isn't running there, be sure to copy the fusionbrain.conf to the right dbus directory and restart dbus (or the entire machine). By default, dbus will not allow services to register on the system bus.

hope that helps.
