Translate axis to act as button

[mnh-jansson]

Joy node maps buttons and axes differently for example xbox controller on different OSs. Is there any way to make an axis act as a button with some kind of threshold? Or would this be outside the scope of this node?

Hello all,
I am trying to use the left Dpad of the Logitech Wireless Gamepad F710 (DirectInput Mode) as buttons to control a head
For now, this check in the code is only checking if you press the axis only in one direction:
self.active &= joy_state.axes[axis] == 1.0
If you want to assign the left Dpad axis 5 for example: 1 action for the up button (+1.0) and 1 other action for the down button (-1.0), it would look something like that:

    head_down:
      type: action
      interface_type: teleop_tools_msgs/action/Increment
      action_name: /head_controller/increment
      action_goal:
        increment_by: [0.0, -0.1]
      axes: [-5]

    head_up:
      type: action
      interface_type: teleop_tools_msgs/action/Increment
      action_name: /head_controller/increment
      action_goal:
        increment_by: [0.0, 0.1]
      axes: [5]

Another option would be to change the Dpad as 4 different buttons
