Functions

• zx_status_t CalculatePllParams (uint32_t input_freq, uint32_t desired_freq, PllParameters * params)

  Calculate phase-locked loop (PLL) parameters.

  In particular, we calculate values of N, M and K such that:

  * The output frequency is >= |desired_freq|.

  * The output frequency is as close as possible to |desired_freq|.

  That is, this function will never produce an output frequency smaller

  than |desired_freq|, but may produce one larger if an exact answer is

  not available.

  The ALC5663 manual states outputs should be in the range 2.048MHz to 40MHz,

  and that K is typically 2.

  We require |input_freq| and |desired_freq| to be > 0.

• template <typename Register, typename AddressType>

  zx_status_t ReadRegister (I2cClient<AddressType> * client, Register * result)

  Read the given register.

• template <typename Register, typename AddressType>

  zx_status_t WriteRegister (I2cClient<AddressType> * client, const Register & value)

  Write the given register.

• zx_status_t SetUpDeviceClocks (Alc5663Client * client, uint32_t sample_rate, uint32_t bclk_frequency)

  Setup the device clocks, ready to play and record audio.

• template <typename Register, typename AddressType, typename F>

  zx_status_t MapRegister (I2cClient<AddressType> * client, F map)

  Read the given register, pass it through the given function, and then

  write the result back.

  If an error occurs in either read or write, we return the status back

  to the user, though provide no way to distinguish which operation

  failed. If this matters, call |ReadRegister| and |WriteRegister|

  directly instead.

• zx_status_t EnableAudioOutput (Alc5663Client * client)

  Enable audio output of the ALC5663 codec.
