Hi Alan,
I'm not near a machine so going by memory and it needs someone to clean
it up so you can better understand it.
The buttons on the joystick are the parts you are using and the device
is /dev/input/event?. Can be event2 event3 event4 etc.
Unplug joystick and look in /dev/input and see what events are there
Plug joystick back in and see what event has been created
Add this event? to gpio with full path restart rivendell daemons and it
should work until you reboot.
A reboot or the usb joystick being unplugged replugged will cause the
event number to change.
Below is a catch all for event matching your joystick buttons and
creates a device /dev/rivbutton1 that can be added to the gpio device.
Copy below to a file and call it 49-local.rules
BUS=="usb", SYSFS{product}=="Generic USB Joystick ",
KERNEL=="event**", NAME="rivbutton1"
Sorry I forgotten where this file goes if Fred could please chime in
here.
List your usb devices and copy your usb joystick device and replace my
"Generic USB Joystick " with yours and I think the spaces maybe
important.
Another thing I noted was cheap joysticks are not shielded. The usb hub
would occasionally disconnect then reconnect. I think this maybe the hub
trying to protect itself from electrical interference.
So build the button board into a good shielded box with good quality
shielded cables including the usb cable.
Gary.
