std::enable_if< has_method_begin< T >::value >::type begin_if_possible(T &t)
Calls the begin() method of t if that method exists.
A super class for object that have to be updated regularly.
Class to keep track of relative position changes of rotary encoders.
int16_t getSpeedMultiply() const
void setSpeedMultiply(int16_t speedMultiply)
int16_t update(Enc_t encval)
An abstract class for rotary encoders that send absolute MIDI events.
void setAddress(MIDIAddress address)
Set the MIDI address.
static int16_t getMaxValue()
Get the maximum possible value that can be returned by getValue.
void forcedUpdate()
Send the current value over MIDI, even if the position of the encoder didn't change.
uint16_t getValue() const
Get the absolute value of the encoder.
void setSpeedMultiply(int16_t speedMultiply)
void update() override
Update this updatable.
void setValue(uint16_t value)
Set the absolute value of the encoder.
GenericMIDIAbsoluteEncoder(Enc &&encoder, MIDIAddress address, int16_t speedMultiply, uint8_t pulsesPerStep, const Sender &sender)
void begin() override
Initialize this updatable.
MIDIAddress getAddress() const
Get the MIDI address.
EncoderState< decltype(encoder.read())> encstate
A type-safe utility class for saving a MIDI address consisting of a 7-bit address,...
An array wrapper for easy copying, comparing, and iterating.
