View Full Version : a USB control
January 7th, 2010, 03:04 PM
Hi I guess this is not so easy but I was thinking about ask here and try in Linux before I give up and run windows.
Is is possible to easy create a one or two button control that use USB.
I want to control a script in the terminal (start and stop the script) and use control to that.
It is maybe a little easy in windows but I like to give Linux a try because it is free and I like to use it for my experiment.

So first of all you will need to make a USB device you can plug into your computer. As this is a non-trivial task, may I propose the following: Go and buy a joystick for little money and paint the buttons red and green (or something like that). You can also remove the circuit from the joystick and put it into a different case or something like that. This saves you the hassle of building a USB circuit and writing drivers. It's also highly likely to be cheaper.
Then you can program a small deamon program that watches for button presses on the connected joystick and reacts according to that. That task shouldn't be harder than in Windows.

Thanks, it was a good idea about the joystick/Gamepad.
But the last one, is that any good guide or something to read?

As for the joystick is concerned, there are some libraries for accepting it. Use google to find one.
BTW: There's already a joystick daemon project around: http://sourceforge.net/projects/joyd/
