Class MMMRdsFrameReceiver

class MMMRdsFrameReceiver;

Description

This mixin is to be implemented by a client wishing to access the raw RDS frames as they are received over the air. Any frames which were corrupted upon receipt will not be sent to the client. RDS frames are received at the rate of 11.4 times per second.

A client receiving these frames should ensure that they are aware when the tuner is retuned, as notified by callback MMMTunerChangeObserver::MTcoFrequencyChanged. Frames will continue to be received after the tune (assuming the new station carries RDS data), but the frames will clearly relate to the new station.
