Detailed Description

Helper class to manage passive connection to DumbDisplay. The only method that should be called in void loop() {} is DDPassiveConnectionHelper::loop(), passing to it some callbacks Note that it will call DumbDisplay::masterReset() when reconnected (i.e. lost previous connection)

Since

v0.9.9

Constructor & Destructor Documentation

DDMasterResetPassiveConnectionHelper()

DDMasterResetPassiveConnectionHelper::DDMasterResetPassiveConnectionHelper ( DumbDisplay &  dumbdisplay, bool  saveAndPlaybackWhenInit = false  )

inline

Parameters

saveAndPlaybackWhenInit

if true, will call DumbDisplay::recordLayerCommands() / DumbDisplay::playbackLayerCommands() before and after calling initializeCallback

Member Function Documentation

loop()

bool DDMasterResetPassiveConnectionHelper::loop ( void(*)()  initializeCallback, void(*)()  updateCallback, void(*)()  disconnectedCallback = NULL  )

inline

Parameters

initializeCallback	called after DumbDisplay is connected (or reconnected)
updateCallback	called to update DumbDisplay components
disconnectedCallback	called after "master reset" DumbDisplay, i.e. lost previous connection

masterReset()

void DDMasterResetPassiveConnectionHelper::masterReset ( )

inline

normally, "master reset" will be called automatically when lost connection; but can be called explicitly; note that if called explicitly, will not call disconnectedCallback; IMPORTANT: should only call it in updateCallback, and after calling it, should return immediately
