Touch Wheel Phidget only button 0 working

[alistair.monaghan]

I've downloaded the Javascript resource for CapacitiveTouch but it only seems to work for the 0 touch button and not the scroll wheel?

There is an option to view the axisField and axisDial so it must be possible - anyone know where I'm going wrong...or have a working example?

The scroll wheel is on channel 4 for the HIN1001, though the example will connect to channel 0 by default.

If you set the channel to 4 before opening it, the scroll wheel will be attached.

Code: Select all

var ch = new phidget22.CapacitiveTouch();

ch.setChannel(4);

//Set up event handlers and other addressing here

ch.open(5000);

Of course! i was so close, many thanks.

ok, thanks again, just following on from this...is there a way to stop the axisDial value at 1 and 0? i.e. it doesn't loop?

You need to handle this special case in your code. In the change handler for the scroll wheel, compare the incoming value with the previous value and ignore it if the change is too large (0.8 or more maybe?). This should cause the scrolling to stop when you hit the seam.
