Fusion Brain program for Linux

**malcom2073** · 06-13-2009, 10:24 PM

Unfortunately I do not have it checked in anywhere, the one kev is working with is the latest copy. I've been on travel for work a lot and have a couple other projects so I haven't had much time to work on it.

Ok I'll take a look at why its not working for me and submit a patch

This is great. If I could get my GPS software to work in Linux then I would absolutely scrap windows. The more applications that can be run under Linux, the less we will be held hostage by windows.

In trying to build the fusion brain files on ARM linux, I get the following errors:

Any ideas on how to quickly fix this? I don't want to start mucking around in the source if I don't have to.

First, you should grab fbd from the linuxice repo as that has the latest code. I also checked in a small fix today.

When I built this I needed to install libusb-0.1-4 and libusb-dev so make sure you have those. You may need libusb-1.0-0 , libusb-1.0-0-dev , libqt4-dev but I think at least the libusb's were for an older version.

Well it build successfully but now I have a new problem:

root@debian:~/fbsvn# ./fbd
Failed to register service: 'org.openice.fbd' on the system bus

**cgalpin** · 06-18-2009, 10:46 PM

Yeah the install/setup for fbd needs to be added to a README and/or the makefile. You can race me to find it, but tripzero mentions what to do in the post where he announced fbd

**cgalpin** · 06-18-2009, 10:48 PM

Duh, that would be this thread

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.

Also you may find this useful for testing with dbus:

Monitor a temperature sensor on input port 1 taking 10 samples (averaged)

watch dbus-send --system --print-reply --dest="org.openice.fbd" /org/openice/fbd org.openice.fbd.fusionbrain.GetAnalogValue int32:1 int32:10

Turn on a relay plugged into output port 0

dbus-send --system --print-reply --dest="org.openice.fbd" /org/openice/fbd org.openice.fbd.fusionbrain.SetSingleOutput int32:0 boolean:true

**PaulF** · 06-19-2009, 06:23 AM

I really need to read up on dbus some time.

But right now, I have a new issue:

Now that the FBD works, when I have fbd running and I try to query it through dbus, I get a segmentation fault. No fusion brain is actually plugged in, I admit. Do you think this is the problem or is it something else?

**chunkyks** · 06-19-2009, 02:34 PM

Some lurkers probably already know what I'm going to do with this, but for now I don't want to announce it on the FB forum just yet.

Tripzero, is there any chance you could create a dummy program, something that does exactly what fbd does from the perspective of dbus, but doesn't require an FB to do it? Just generate random numbers for a couple of analog inputs, and signal them on the bus that you use. Is that possible?

Thanks,
