VS1053Config()

VS1053Config ( )

inline

Member Function Documentation

clear()

virtual void clear ( )

inlinevirtualinherited

copyFrom()

void copyFrom ( AudioInfo  info )

inlineinherited

Same as set.

equals()

bool equals ( AudioInfo  alt )

inlineinherited

Returns true if alt values are the same like the current values.

equalsExSampleRate()

bool equalsExSampleRate ( AudioInfo  alt )

inlineinherited

Checks if only the sample rate is different.

logInfo()

virtual void logInfo ( const char *  source = "" )

inlinevirtualinherited

Reimplemented in I2SConfigESP32, I2SConfigESP32V1, and I2SConfigStd.

operator bool()

operator bool ( )

inlineinherited

Returns true if all components are defined (no component is 0)

operator!=()

bool operator!= ( AudioInfo  alt )

inlineinherited

Returns true if alt values are the different from the current values.

operator==()

bool operator== ( AudioInfo  alt )

inlineinherited

Returns true if alt values are the same like the current values.

Member Data Documentation

bits_per_sample

uint8_t bits_per_sample = DEFAULT_BITS_PER_SAMPLE

inherited

Number of bits per sample (int16_t = 16 bits)

channels

uint16_t channels = DEFAULT_CHANNELS

inherited

Number of channels: 2=stereo, 1=mono.

cs_pin

uint8_t cs_pin = VS1053_CS

Chip-select (control) pin for the VS1053 SPI interface. Set this to the board-specific CS pin (e.g. VS1053_CS).

cs_sd_pin

int16_t cs_sd_pin = VS1053_CS_SD

Optional chip-select pin for an attached SD card (if present).

dcs_pin

uint8_t dcs_pin = VS1053_DCS

Data/command select (DCS) pin used by some VS1053 modules.

dreq_pin

uint8_t dreq_pin = VS1053_DREQ

Data request (DREQ) pin — used by the VS1053 to signal it can accept more data. Configure this to the board's DREQ pin (e.g. VS1053_DREQ).

is_encoded_data

bool is_encoded_data = false

When true the stream expects encoded input data (MP3/WAV/etc). When false (default) the stream treats input as raw PCM samples.

is_midi

bool is_midi = false

When true enable MIDI streaming mode (this also forces encoded mode).

is_start_spi

bool is_start_spi = true

If true the driver will call SPI.begin() during initialization. Set to false if SPI is managed externally by the application.

mode

RxTxMode mode = TX_MODE

Operation mode (transmit/receive). Default: TX_MODE (playback).

reset_pin

int16_t reset_pin = VS1053_RESET

Optional reset pin for the VS1053 module. Set to -1 if unused. When valid the pin will be toggled during initialization.

sample_rate

sample_rate_t sample_rate = DEFAULT_SAMPLE_RATE

inherited

Sample Rate: e.g 44100.
