Detailed Description

Specific subclass for LPS25 variant

Member Function Documentation

getDataRate()

lps25_rate_t Adafruit_LPS25::getDataRate

(

void

)

Gets the current rate at which pressure and temperature measurements are taken.

Returns

lps25_rate_t The current data rate

setDataRate()

void Adafruit_LPS25::setDataRate

(

lps25_rate_t

new_data_rate

)

Sets the rate at which pressure and temperature measurements.

Parameters

new_data_rate

The data rate to set. Must be a lps25_rate_t

powerDown()

void Adafruit_LPS25::powerDown

(

bool

power_down

)

Puts the sensor into power down mode, shutting the sensor down.

Parameters

power_down

configureInterrupt()

void Adafruit_LPS25::configureInterrupt	(	bool	activelow,
		bool	opendrain,
		bool	pres_high = false,
		bool	pres_low = false
	)

Configures the INT pin, by default it will output DRDY signal.

Parameters

activelow	Pass true to make the INT pin drop low on interrupt
opendrain	Pass true to make the INT pin an open drain output
pres_high	If true, interrupt fires on high threshold pass
pres_low	If true, interrupt fires on low threshold pass

_init()

bool Adafruit_LPS25::_init ( int32_t  sensor_id )

protectedvirtual

Initializer for post i2c/spi init.

Parameters

sensor_id

Optional unique ID for the sensor set

Returns

True if chip identified and initialized

Implements Adafruit_LPS2X.
