Complete Phidget N00b here.
My goal is to get the HIN1000_0 responding to touches on any of it's seven touchpads.

To that end, I've downloaded, walked through and ran the example code

CapacitiveTouch.py.

Thing is, I can't figure out how to get touchValue to correspond to the channel of the touchpad that was touched. This defaults to 0 or can be set via setChannel().

Each CapacitiveTouch object can only be assigned to one button on the HIN1000. You'll need to make multiple objects to use multiple buttons at the same time:

Code: Select all

ch0 = CapacitiveTouch()
ch1 = CapacitiveTouch()

def TouchHandler(e, touchValue):
    print("Channel %d Touch Value: %f" % (e.getChannel(),touchValue))

ch0.setOnTouchHandler(TouchHandler)
ch1.setOnTouchHandler(TouchHandler)

ch0.setChannel(0)
ch1.setChannel(1)

ch0.openWaitForAttachment(5000)
ch1.openWaitForAttachment(5000)

print("Gathering data for 10 seconds...")
time.sleep(10)

ch0.close()
ch1.close()

If you plan on using all 7 channels, it would be cleaner to create an array of CapacitiveTouch objects and use loops to run through all of these steps.

Thanks for this. That got me on my way. Next up, trying to wire this up with wxPython.
