Inheritance diagram for Adafruit_ADS1115:

Public Member Functions
	Adafruit_ADS1115 (TwoWire &, uint8_t i2cAddr=ADS1X15_ADDRESS)
	Bind a 16-bit ADS1115; defaults are gain 2/3 and 128 samples/second.
Public Member Functions inherited from Adafruit_ADS1X15
	Adafruit_ADS1X15 (TwoWire &w, uint8_t i2c_addr=ADS1X15_ADDRESS)
	Bind the I2C bus and address. Use an ADS1015/ADS1115 subclass to set resolution defaults.
bool	begin ()
	Initialize I2C and probe the configured address; return true on acknowledgement.
int16_t	readADC_SingleEnded (uint8_t channel)
	Block for a single-ended raw ADC conversion.
int16_t	readADC_Differential_0_1 ()
	Block for raw signed ADC counts from AIN0 minus AIN1.
int16_t	readADC_Differential_0_3 ()
	Block for raw signed ADC counts from AIN0 minus AIN3.
int16_t	readADC_Differential_1_3 ()
	Block for raw signed ADC counts from AIN1 minus AIN3.
int16_t	readADC_Differential_2_3 ()
	Block for raw signed ADC counts from AIN2 minus AIN3.
void	startComparator_SingleEnded (uint8_t channel, int16_t threshold)
	Start continuous comparator operation for channel 0 through 3.
int16_t	getLastConversionResults ()
	Read the conversion register and return signed counts at the device resolution.
float	computeVolts (int16_t counts)
	Convert counts to volts using the configured gain and ADC resolution.
void	setGain (adsGain_t gain)
	Cache the PGA gain used by subsequent conversions and computeVolts().
adsGain_t	getGain ()
	Return the cached PGA gain.
void	setDataRate (uint16_t rate)
	Cache a device-specific RATE_ADS1015_* or RATE_ADS1115_* register setting.
uint16_t	getDataRate ()
	Return the cached data-rate register setting, not a numeric samples/second value.
void	startADCReading (uint16_t mux, bool continuous)
	Start a conversion without waiting.
bool	conversionComplete ()
	Return the configuration OS bit; used to poll single-shot completion.
