An +example linux device file would be: + +/dev/input/event5 + +The pd user specifies device type as a string - i.e. "SideWinder Dual Strike", and +this external outputs lists containing an index, and the linux device file where +each device of the given type was found. For example + +{0, /dev/input/event5} +{1, /dev/input/event6} + +These lists can be routed in PD with the [route] object - see the help file for +[route] for more details. + +In order to make this code compile, I had to install the following libraries +onto my system: + + libhal-dev + libglib2.0-dev + libdbus-glib-1-dev + +In a debian-based system, they can be installed with apt-get, as in: + sudo apt-get install libhal-dev + +To see if you have the right libraries installed in order to compile, you can +try compiling the test_noticer.c file, by running the test_noticer_compile.sh +shell script, as follows: + +source test_noticer_compile.sh + +Then, run test_noticer, and when it's running you should see messages when +you plug, or un-plug a joystick. + +Thanks to Dan Willmans, Seth Nickell, and David Zeuthen for their +invaluable help with the whole dbus/hal part. Also, thanks to Hans-Christoph +Steiner for his help with (and creation of) the joystick external. + +For good examples and reference on dbus/hal, please see: +NetworkManager.c: http://cvs.gnome.org/viewcvs/NetworkManager/src/NetworkManager.c?rev=1.100&view=markup +libhal.h: http://webcvs.freedesktop.org/hal/hal/libhal/libhal.h?rev=1.32&view=markup + +Parts of this code were pulled from those examples. + |
