)
inline

◆ begin() [2/3]

bool begin ( uint32_t  sample_rate,
uint8_t  bits 
)
inline

Initialize the codec: software reset, set TDM/I2S format and sample rate, set the default amplifier output level and put the amplifier into shutdown mode (call start() to enable the output).

Parameters
rateI2S sample rate (one of TAS2563SampleRate)
word_sizeI2S word size in bits (16, 20, 24, 32)
formatDigital audio interface format (I2S or left-justified) Initializes the codec for I2S with the given sample rate (in Hz, mapped to the nearest supported TAS2563SampleRate) and bits per sample

◆ begin() [3/3]

bool begin ( uint32_t  sample_rate,
uint8_t  bits,
codec_mode_t  mode,
i2s_format_t  fmt,
bool  is_master,
uint8_t  channels 
)
inlineoverridevirtual

Initializes the codec.

Implements ZephyrDriverCommon.

◆ getInputVolume()

virtual int getInputVolume ( )
inlinevirtualinherited

Provides the input volume in % (0...100) that was set with setInputVolume()

◆ getRevisionId()

bool getRevisionId ( uint8_t &  rev_id)
inline

Read the chip revision / product ID register.

◆ getVolume()

virtual int getVolume ( )
inlinevirtualinherited

Provides the output volume in % (0...100) that was set with setVolume()

◆ getWire()

i2c_bus_handle_t getWire ( )
inlineinherited

Provides the actual I2C communication object.

◆ isInputVolumeSupported()

virtual bool isInputVolumeSupported ( )
inlinevirtualinherited

Returns true if the driver supports setting the input volume, false otherwise. By default we return false, but some drivers (e.g. WM8962) override this to return true.

Reimplemented in DA7212, WM8904, and WM8962.

◆ readReg()

bool readReg ( uint8_t  reg,
uint8_t &  value 
)
inlineprotectedinherited

Reads a single byte from an 8 bit register address.

◆ readReg16()

bool readReg16 ( uint8_t  reg,

)
inlineprotectedinherited

Reads a 16 bit (big endian) value from an 8 bit register address.

bool selectBook ( uint8_t  book)
inline

Set the active register book (only Book 0 is defined by this driver)

bool selectPage ( uint8_t  page)
inline

Set the active register page (only Page 0 is defined by this driver)

◆ setActive()

virtual bool setActive ( codec_mode_t  mode)
inlinevirtualinherited

Activates/deactivates the playback and/or capture path at runtime (without reconfiguring the codec), based on codec_mode_t (CODEC_MODE_DECODE: playback active, CODEC_MODE_ENCODE: capture active). By default this just mutes/unmutes all outputs depending on CODEC_MODE_DECODE; chip specific subclasses that support muting the input path independently override this to also mute/unmute the capture path depending on CODEC_MODE_ENCODE.

Reimplemented in DA7212, WM8904, and WM8962.

◆ setAddress()

void setAddress ( uint8_t  addr)
inlineinherited

Defines the I2C address of the codec.

inline

Set the amplifier output level register value directly (see AMP_LEVEL_* constants)

◆ setDevices()

virtual bool setDevices ( input_device_t  input_device,
output_device_t  output_device 
)
inlinevirtualinherited

Selects the ADC input source / DAC output destination. By default this is a no-op; chip specific subclasses that support input/output routing override this to configure the corresponding registers.

Reimplemented in DA7212, MAX98091, TAS6422DAC, TLV320AIC3110, TLV320DAC310x, WM8904, and WM8962.
