Member Enumeration Documentation

mux

enum ADS1115::mux

multiplexer setting options

first index is positive lead, second index negative

only one index means single ended measurements

e.g. AIN0_3 differentially measures voltage on pin 0 against pin 3

Constructor & Destructor Documentation

ADS1115()

ADS1115::ADS1115 ( Sink< I2C::Request > &  bus, uint8_t  address = 0b1001000, enum range  fs = FS6144, enum dataRate  dr = SPS64, enum mux  mx = AIN0  )

inline

configure and start voltage conversions

Parameters

bus	I2C request queue
address	7bit I2C address of ADS1115 device
fs	full scale range on inputs
dr	data rate / conversion speed
mx	initial multiplexer setting

Member Function Documentation

updateConfig()

void ADS1115::updateConfig ( )

inline

update device config

sends parameters set in class to device

volts()

double ADS1115::volts ( )

inline

Returns

last measured voltage [V]
