12. API - Joystick¶
The joystick on the Sense HAT is an excellent tool for providing a user
interface on Pis without an attached keyboard. The SenseStick class
provides several different paradigms for programming such an interface:
- At its simplest, you can poll the state of the joystick with various
attributes like
SenseStick.up. - You can use event-driven programming by assigning handlers to attributes
like
SenseStick.when_up. - You can also treat the joystick like an iterable and write transformations the convert events into other useful outputs.
