captouch module
- class captouch.CaptouchPetalPadsState(*args, **kwargs)
Current state of pads on a captouch petal.
Not all petals have all pads. Top petals have a a base, cw and ccw pad. Bottom petals have a base and tip pad.
- property base: bool
True if the petal’s base is currently touched.
- property ccw: bool
True if the petal’s counter clockwise pad is currently touched.
- property cw: bool
True if the petal’s clockwise pad is currently touched.
- property tip: bool
True if the petals’s tip is currently touched.
- class captouch.CaptouchPetalState(*args, **kwargs)
- property bottom: bool
True if this is a bottom petal.
- property pads: CaptouchPetalPadsState
State of individual pads of the petal.
- property position: Tuple[int, int]
Polar coordinates of touch on petal in the form of a (distance, angle) tuple.
The units are arbitrary, but centered around (0, 0).
An increase in distance means the touch is further away from the centre of the badge.
An increase in angle means the touch is more clockwise.
- property pressed: bool
True if any of the petal’s pads is currently touched.
- property pressure: int
How strongly the petal is currently being touched, in arbitrary units.
- property top: bool
True if this is a top petal.
- class captouch.CaptouchState(*args, **kwargs)
State of captouch sensors, captured at some time.
- property petals: List[CaptouchPetalState]
State of individual petals.
Contains 10 elements, with the zeroth element being the pad closest to the USB port. Then, every other pad in a clockwise direction.
Pads 0, 2, 4, 6, 8 are Top pads.
Pads 1, 3, 5, 7, 9 are Bottom pads.
- captouch.calibration_active() bool
Returns true if the captouch system is current recalibrating.
- captouch.calibration_request() None
Attempts to start calibration of captouch controllers. No-op if a calibration is already active.
- captouch.read() CaptouchState
Reads current captouch state from hardware and returns a snapshot in time.
