class Adafruit_VS1053_FilePlayer

The Adafruit_VS1053_FilePlayer class is derived from the Adafruit_VS1053 class and provides high level functions for playing files stored on the VS1053 breakout SD Card reader.

Public Methods:

Adafruit_VS1053_FilePlayer (int8_t mosi, int8_t miso, int8_t clk, int8_t rst, int8_t cs, int8_t dcs, int8_t dreq, int8_t cardCS) - Software SPI constructor. Uses Software SPI, so you must specify all SPI pins.

Adafruit_VS1053_FilePlayer (int8_t rst, int8_t cs, int8_t dcs, int8_t dreq, int8_t cardCS) - Hardware SPI constructor. Uses Hardware SPI and assumes the default SPI pins. This is what you'll likely use if you're using the shield.

boolean begin(void) - Initialize communication and reset the chip. Returns true if a VS1053 is found

boolean useInterrupt(uint8_t type) - Specifies the interrupt to use for interrupt-driven playback. Valid arguments are:

boolean startPlayingFile(char *trackname) - Begin playing the specified file from the SD card using interrupt-driven playback. This allows your program to perform other tasks as the file is playing.

boolean playFullFile(char *trackname) - Play the complete file. This function will not return until the playback is complete.

Public Member Variables:

File currentTrack - File currently being played

boolean playingMusic - True if playback in progress

class Adafruit_VS1053

The Adafruit_VS1053 class implements an interface to the basic VS1053 functionality. For more detail on the operation of the VS1053 chip, please refer to the documentation on the Downloads page (see the link to the left). Its a little more powerful but it's also harder to use. We suggest sticking to the FilePlayer class which abstracts a lot of this out for you
