Detailed Description

An implementation of RotaryEncoder that supports the most common types of rotary encoder, needed no additional hardware in most cases. It is based on a state machine of valid possible states, and should handle quarter turn encoders properly. Interrupt mode is not mandatory, but be aware that without interrupts the polling is approximately every 2 milliseconds.

Constructor & Destructor Documentation

◆ HwStateRotaryEncoder() [1/2]

HwStateRotaryEncoder::HwStateRotaryEncoder	(	pinid_t	pinA,
		pinid_t	pinB,
		EncoderCallbackFn	callback,
		HWAccelerationMode	accelerationMode = HWACCEL_REGULAR,
		EncoderType	encoderType = FULL_CYCLE )

Create an instance of a hardware rotary encoder specifying the A and B pin, the acceleration parameters and encoder type. It is your responsibility to register this encoder with switches using setEncoder(n, encoderPtr) if you use the constructor.

Parameters

pinA	the A pin of the encoder
pinB	the B pin of the encoder
callback	the function callback to be called when triggered
accelerationMode	the amount of acceleration to use

◆ HwStateRotaryEncoder() [2/2]

HwStateRotaryEncoder::HwStateRotaryEncoder	(	pinid_t	pinA,
		pinid_t	pinB,
		EncoderListener *	listener,
		HWAccelerationMode	accelerationMode = HWACCEL_REGULAR,
		EncoderType	encoderType = FULL_CYCLE )

Create an instance of a hardware rotary encoder specifiying the A and B pin, the acceleration parameters and encoder type. It is your responsibility to register this encoder with switches using setEncoder(n, encoderPtr) if you use the constructor. This constructor takes an OO listener instead of a callback function, the listener implements EncoderListener.

Parameters

pinA	the A pin of the encoder
pinB	the B pin of the encoder
listener	the OO listener extending from EncoderListener
accelerationMode	the amount of acceleration to use
