analogReadCached()

uint16_t readCache::analogReadCached	(	uint8_t	pin,
		uint8_t	trigPin = 0,
		uint8_t	_type = IN_ANALOG )

Cached analogRead (with an optional trigger pin, e.g. for ultrasonic).

digitalReadCached()

(

uint8_t

pin

)

Cached digitalRead.

TBD

invalidateInputCache()

void readCache::invalidateInputCache

(

)

Invalidate the cached read so the next read hits the hardware.
