Member Function Documentation

available()

virtual int available ( )

pure virtual

Implemented in AnalogDriverArduino, AnalogDriverESP32, AnalogDriverESP32V1, AnalogDriverESP32V2, AnalogDriverMBED, and AnalogDriverZephyr.

availableForWrite()

virtual int availableForWrite ( )

inlinevirtual

Reimplemented in AnalogDriverMBED, AnalogDriverArduino, and AnalogDriverZephyr.

begin()

virtual bool begin ( AnalogConfig  cfg )

pure virtual

Implemented in AnalogDriverArduino, AnalogDriverMBED, AnalogDriverZephyr, and AnalogDriverESP32.

end()

virtual void end ( )

pure virtual

Implemented in AnalogDriverArduino, AnalogDriverESP32, AnalogDriverESP32V1, AnalogDriverESP32V2, AnalogDriverMBED, and AnalogDriverZephyr.

readBytes()

virtual size_t readBytes ( uint8_t *  dest, size_t  size_bytes  )

pure virtual

Implemented in AnalogDriverArduino, AnalogDriverESP32, AnalogDriverESP32V1, AnalogDriverESP32V2, AnalogDriverMBED, and AnalogDriverZephyr.

scaleTo16Bits()

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

inlinestaticprotected

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()

virtual size_t write ( const uint8_t *  src, size_t  size_bytes  )

inlinevirtual

Reimplemented in AnalogDriverArduino, AnalogDriverESP32, AnalogDriverESP32V1, AnalogDriverESP32V2, AnalogDriverMBED, and AnalogDriverZephyr.
