deluge::hid::encoders::DetentedEncoder Class Reference

#include <encoders.h>

Public Member Functions
	DetentedEncoder (const DetentedEncoder &)=delete
DetentedEncoder &	operator= (const DetentedEncoder &)=delete
void	applyEdges (int8_t edges)
bool	pending () const
	True if any detent steps are waiting to be consumed.
int32_t	take ()
	Returns the accumulated signed detent count and resets pos to 0.
void	restore (int32_t val)

Private Attributes
int32_t	edgeAccumulator = 0
	Accumulates A-pin edges until we have a full detent click. IRQ-only.
std::atomic_int32_t	pos = 0
	Written by the IRQ (applyEdges), drained by the encoder task.

Detailed Description

Black function encoders (SCROLL_X/Y, TEMPO, SELECT) are detented. Two A-pin edges = one quadrature cycle = one detent click.

Member Function Documentation

restore()

void deluge::hid::encoders::DetentedEncoder::restore ( int32_t val )

inline

Puts a value back (used by the SD card-routine retry path). fetch_add rather than store so a detent that arrived from the IRQ since take() isn't clobbered.
