halPlayTune_P#

void halPlayTune_P (uint8_t PGM * tune, bool bkg)

Plays a tune on the piezo buzzer.

The tune is played in the background if ::bkg is true. Otherwise, the API blocks until the playback of the tune is complete. halPlayTune_P() is not meant to be called back-to-back.

A tune is implemented as follows:

uint8_t PGM hereIamTune[] = {  //All tunes are stored in flash.
   NOTE_B4,  1,                //Plays the note B4 for 100 milliseconds.
   0,        1,                //Pause for 100 milliseconds.
   NOTE_B5,  5,                //Plays the note B5 for 500 milliseconds.
   0,        0                 //NULL terminates the tune.
 };

halStackIndicatePresence#

void halStackIndicatePresence (void )

Causes something to happen on a node (such as playing a tune on the buzzer) that can be used to indicate where it physically is.
