TuneControl (UORB message)

This message is used to control the tunes, when the tune_id is set to CUSTOM. then the frequency, duration are used otherwise those values are ignored.

TOPICS: tune_control

Fields

Name Type Unit [Frame] Range/Enum Description
timestamp uint64 time since system start (microseconds)
tune_id uint8 tune_id corresponding to TuneID::* from the tune_defaults.h in the tunes library
tune_override bool if true the tune which is playing will be stopped and the new started
frequency uint16 in Hz
duration uint32 in us
silence uint32 in us
volume uint8 value between 0-100 if supported by backend
