Hi,
We are creating a set of headphones that we would like to beep when the battery is low. One way we have of doing this is that we have an MCU on the Headphone side that transmits the battery status to the Master (Source) , which then overlays the desired beep onto the current audio output. We don't want to do it through a LED status as the user is more than likely wearing the headphones thus can't see it.
I noticed there is a tone generator that exists for the production tests. Is it possible that this could then be enabled for host controlled mode. Is this a feature that could make it into the autonomous mode (currently this is the one of the main drivers we have for an external MCU on our headphones) and could this also be mixed onto a currently playing track?
Thanks,
Jeoff
