Public Functions Documentation¶

function DaisyField¶

inline DaisyField()

function ~DaisyField¶

inline ~DaisyField()

function Init¶

void Init(
    bool boost =false
)

Initializes the Daisy Field, and all of its hardware.

function DelayMs¶

void DelayMs(
    size_t del
)

Parameters:

del Delay time in ms.

Wait some ms before going on.

function StartAudio¶

void StartAudio(
    AudioHandle::InterleavingAudioCallback cb
)

Parameters:

cb Interleaved callback function

Starts the callback

function StartAudio¶

void StartAudio(
    AudioHandle::AudioCallback cb
)

Parameters:

cb multichannel callback function

Starts the callback

function StopAudio¶

void StopAudio()

Stops the audio if it is running.

function ChangeAudioCallback¶

void ChangeAudioCallback(
    AudioHandle::InterleavingAudioCallback cb
)

Parameters:

cb New interleaved callback function.

Switch callback functions

function ChangeAudioCallback¶

void ChangeAudioCallback(
    AudioHandle::AudioCallback cb
)

Parameters:

cb New multichannel callback function.

Switch callback functions

function SetAudioSampleRate¶

void SetAudioSampleRate(
    SaiHandle::Config::SampleRate samplerate
)

Updates the Audio Sample Rate, and reinitializes. Audio must be stopped for this to work.

function AudioSampleRate¶

float AudioSampleRate()

Returns the audio sample rate in Hz as a floating point number.

function SetAudioBlockSize¶

void SetAudioBlockSize(
    size_t blocksize
)

Sets the number of samples processed per channel by the audio callback.

function AudioBlockSize¶

size_t AudioBlockSize()

Returns the number of samples per channel in a block of audio.

function AudioCallbackRate¶

float AudioCallbackRate()

Returns the rate in Hz that the Audio callback is called

function StartAdc¶

void StartAdc()

Starts Transfering data from the ADC

function StopAdc¶

void StopAdc()

Stops Transfering data from the ADC

function StartDac¶

void StartDac()

Turns on the built-in 12-bit DAC on the Daisy Seed This is now deprecated and does nothing. The polling use of the DACs now handles starting the tranmission.

function ProcessAnalogControls¶

void ProcessAnalogControls()

Processes the ADC inputs, updating their values

function ProcessDigitalControls¶

void ProcessDigitalControls()

Process tactile switches and keyboard states

function ProcessAllControls¶

inline void ProcessAllControls()

Process Analog and Digital Controls

function SetCvOut1¶

void SetCvOut1(
    uint16_t val
)

Sets the output of CV out 1 to a value between 0-4095 that corresponds to 0-5V

function SetCvOut2¶

void SetCvOut2(
    uint16_t val
)

Sets the output of CV out 2 to a value between 0-4095 that corresponds to 0-5V
