Public Member Functions

 AudioSourceSD (const char *startFilePath="/", const char *ext=".mp3", int chipSelect=PIN_CS, bool setupIndex=true)
 Default constructor.
 
virtual void begin () override
 Reset actual stream and move to root.
 
void end ()
 
int index ()
 Provides the current index position.
 
virtual bool isAutoNext ()
 Returns default setting go to the next.
 
virtual StreamnextStream (int offset=1) override
 Returns next audio stream.
 
virtual StreampreviousStream (int offset)
 Returns previous audio stream.
 
virtual StreamselectStream (const char *path) override
 Returns audio stream by path.
 
virtual StreamselectStream (int index) override
 Returns audio stream at the indicated index (the index is zero based, so the first value is 0!)
 
void setFileFilter (const char *filter)
 
virtual StreamsetIndex (int index)
 same as selectStream - I just prefer this name
 
virtual bool setMetadataCallback (void(*fn)(MetaDataType info, const char *str, int len), ID3TypeSelection sel=SELECT_ICY)
 
virtual void setPath (const char *p)
 Allows to "correct" the start path if not defined in the constructor.
 
virtual void setTimeout (int millisec)
 Sets the timeout of Stream in milliseconds.
 
virtual void setTimeoutAutoNext (int millisec)
 Sets the timeout which is triggering to move to the next stream. - the default value is 500 ms.
 
long size ()
 Provides the number of files (The max index is size()-1): WARNING this is very slow if you have a lot of files in many subdirectories.
 
virtual int timeoutAutoNext ()
 Provides the timeout which is triggering to move to the next stream.
 
const char * toStr ()
 provides the actual file name
