Functions high level overview

DRAFT !! Frugal IoT - functions high level

This is a high level view of the functions that occur on lots of classes of Frugal IoT

Abbreviations	Means
S, A, or C.	An Actuator, Sensor or Control
INxxx or OUTxxx	An INuint16 INbool INcolor etc

Incoming to Actuators

Function
mqtt.dispatch(path, payload)	if isSet calls Actuator.dispatchTwigAll
A.dispatchTwigAll(twig,payload,isSet)	calls all A.dispatchTwig
A.dispatchTwig(id, leaf, payload, isSet=true)	Calls each INxxx.dispatchLeaf then A.act if any change
A.act()	Reads from INxxx.value etc and takes action (such as changing outputs)

Incoming to Sensors -

As for Actuators:

mqtt.dispatch => (if isSet) Sensor.dispatchTwigAll -> s.dispatchTwig -> OUTxxx.dispatchLeaf but doesnt call act

Outgoing sensor readings

Function
Loop (or periodically)	readAndSet
S.readAndSet	reads physical sensor, calls S.set or OUTxxx.set directly
S.set(...)	calls OUTxxx.set
OUTxxx.set	If changed calls Mqtt.messageSend and sendWired
OUTxxx.sendWired	calls Mqtt.messageSend

Incoming to Control

Function
mqtt.dispatch(path, payload)	calls Control.dispatchTwigAll and Control.dispatchPathAll
C.dispatchTwigAll	calls each INxxx & OUTxxx.dispatchLeaf then if changed C.act()
C.act()	Makes state changes, the result of one or more messages being received, may call OUTxxx.set
OUTxxx.set	see Outgoing sensor readings
