Inheritance diagram for AnalogAudioStream:
Public Member Functions | |
| AnalogAudioStream ()=default | |
| Default constructor. | |
| AnalogAudioStream (AnalogDriverBase &driver) | |
| Constructor to define a custom driver. | |
| virtual | ~AnalogAudioStream () |
| Destructor. | |
| virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
| Adds target to be notified about audio changes. | |
| virtual AudioInfo | audioInfo () override |
| provides the actual input AudioInfo | |
| virtual AudioInfo | audioInfoOut () |
| provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream | |
| int | available () override |
| int | availableForWrite () override |
| bool | begin () override |
| Reopen with last config. | |
| bool | begin (AnalogConfig cfg) |
| starts the DAC | |
| virtual void | clearNotifyAudioChange () |
| Deletes all change notify subscriptions. | |
| AnalogConfig & | config () |
| AnalogConfig | defaultConfig (RxTxMode mode=TX_MODE) |
| Provides the default configuration. | |
| AnalogDriverBase * | driver () |
| Provides access to the driver. | |
| void | end () override |
| stops the I2S and unistalls the analog | |
| virtual void | flush () override |
| bool | isNotifyActive () |
| Checks if the automatic AudioInfo update is active. | |
| virtual | operator bool () |
| size_t | readBytes (uint8_t *data, size_t len) override |
| virtual size_t | readSilence (uint8_t *buffer, size_t length) |
| Source to generate silence: just sets the buffer to 0. | |
| virtual bool | removeNotifyAudioChange (AudioInfoSupport &bi) |
| Removes a target in order not to be notified about audio changes. | |
| virtual void | setAudioInfo (AudioInfo info) |
| updates the sample rate dynamically | |
| void | setNotifyActive (bool flag) |
| Deactivate/Reactivate automatic AudioInfo updates: (default is active) | |
| size_t | write (const uint8_t *data, size_t len) override |
| ESP32 only: writes the data to the I2S interface. | |
| virtual size_t | write (uint8_t ch) override |
| virtual void | writeSilence (size_t len) |
| Writes len bytes of silence (=0). | |
Protected Member Functions | |
