AnalogDriverMBED()

AnalogDriverMBED ( )

default

Default constructor.

~AnalogDriverMBED()

virtual ~AnalogDriverMBED ( )

inlinevirtual

Destructor.

Member Function Documentation

available()

virtual int available ( )

inlineoverridevirtual

Implements AnalogDriverBase.

availableForWrite()

int availableForWrite ( )

inlinevirtual

Reimplemented from AnalogDriverBase.

begin()

bool begin ( AnalogConfig  cfg )

inlinevirtual

starts the DAC

Implements AnalogDriverBase.

end()

void end ( )

inlineoverridevirtual

stops the I2S and unistalls the driver

Implements AnalogDriverBase.

flush()

void flush ( )

inline

readBytes()

size_t readBytes ( uint8_t *  dest, size_t  size_bytes  )

inlineoverridevirtual

Implements AnalogDriverBase.

scaleTo16Bits()

static void scaleTo16Bits ( uint8_t *  data, size_t  size_bytes, int  adc_bits, bool  is_centered  )

inlinestaticprotectedinherited

Scales int16_t samples with adc_bits resolution to the full 16 bit range. If the samples are not centered yet, the midpoint of the ADC range is subtracted first.

write()

size_t write ( const uint8_t *  src, size_t  size_bytes  )

inlineoverridevirtual

writes the data to the I2S interface

Reimplemented from AnalogDriverBase.

writeBuffer()

size_t writeBuffer ( )

inlineprotected

The ringbuffer is used to make sure that we can write full SampleBuffers.
