PhidKey pattern that polls values from a human device interface, based on a named slot

superclass: Pattern

*new(key, device, repeats)

key key defined in the Spec of the device, pointing to a slot like a button or an axis

device a GeneralHIDDevice, or an element from the GeneralHID.deviceList, which will then be opened by the pattern

repeats number of values to return (defaults to inf)

// example
// build the device list and start the event loop:
GeneralHID.buildDeviceList;
GeneralHID.startEventLoop;

// find an Impact game device and open it:
a = GeneralHID.open( GeneralHID.findBy( 1973 ) );
// define a spec:
(
a.add( \lx, [3,0]); // left x
a.add( \ly, [3,1]); // left y
a.add( \rx, [3,2]); // right x
a.add( \ry, [3,5]); // right y
);
// or find a spec defined previously for this device:
c = a.findSpec;
// set it:
a.setSpec( c[0] );
// inspect the spec
a.spec.map
a.caps;
// boot the server
s.boot;
// simple example:
p = Pbind(
\degree, ( PhidKey( \lx, a, inf )*12 ).round(1),
\dur, 0.25
).play;
p.stop;
// more complex example, showing multichannel expansion and sequences of slots:
p = Pbind(
\degree, ( PhidKey( Pseq([[\lx,\ly],\rx,\ry],inf), a, inf )*12 ).round(1),
\dur, 0.25
).play;
p.stop;
// clean up: close the device and stop the eventloop
a.close;
GeneralHID.stopEventLoop;
