Member Function Documentation

begin()

bool m5::unit::UnitADS1110::begin ( )

overridevirtual

Reimplemented from m5::unit::UnitADS11XX.

generalReset()

bool m5::unit::UnitADS1110::generalReset ( )

overridevirtual

General reset.

Reset using I2C general call

Returns

True if successful

Warning

This is a reset by General command, the command is also sent to all devices with I2C connections

Reimplemented from m5::unit::UnitADS11XX.

get_interval()

uint32_t m5::unit::UnitADS1110::get_interval ( const uint8_t rate )

overrideprotectedvirtual

Reimplemented from m5::unit::UnitADS11XX.

measureSingleshot()

bool m5::unit::UnitADS1110::measureSingleshot	(	ads1110::Data &	data,
		const ads1110::Sampling	rate,
		const ads1110::PGA	pga )

Measurement single shot.

Parameters

[out]	data	Measuerd data
	rate	Data sampling rate
	pga	Programmable Gain Amplifier

Returns

True if successful

Note

Blocked until the end of measurement

Blocking time depends on rate value

Warning

During periodic detection runs, an error is returned

Each setting is overwritten

(

const ads1110::Sampling

rate

)

Write the Sampling rate.

Parameters

rate	Sampling rate
