Detailed Description

Class that stores state and functions for interacting with the PCT2075 I2C Digital Potentiometer.

Member Function Documentation

begin()

boolean Adafruit_PCT2075::begin	(	uint8_t	i2c_address = PCT2075_I2CADDR_DEFAULT,
		TwoWire *	wire = &Wire
	)

Sets up the hardware and initializes I2C.

Parameters

i2c_address	The I2C address to be used.
wire	The Wire object to be used for I2C connections.

Returns

True if initialization was successful, otherwise false.

getTemperature()

float Adafruit_PCT2075::getTemperature

(

void

)

Gets the current temperature measurement.

Returns

The current temperature in degrees C. Resolution is 0.125 C

getIdleTime()

float Adafruit_PCT2075::getIdleTime

(

void

)

Gets the amount of time the sensor waits between measurements.

Returns

The amount of idle time in seconds

setIdleTime()

void Adafruit_PCT2075::setIdleTime

(

float

new_idle_time

)

Sets the amount of time the sensor waits between measurements.

Parameters

new_idle_time

The new idle time in seconds. Must be >= 0.1, <= 3.2 and a multiple of 0.1 (100 ms)

setActiveHigh()

void Adafruit_PCT2075::setActiveHigh

(

bool

active_high

)

Sets the polarity of the INT pin.

Parameters

active_high

The polarity of the INT pin. If false the INT pin is Hi-Z on alert. If true, the INT pin is connected to ground on alert.

getHighTemperatureThreshold()

float Adafruit_PCT2075::getHighTemperatureThreshold

(

void

)

Gets the high temperature threshold in degrees C.

Returns

The current high temperature threshold in degrees C. Resolution is 0.5 C

setHighTemperatureThreshold()

void Adafruit_PCT2075::setHighTemperatureThreshold

(

float

new_temp_threshold

)

Sets the high temperature threshold in degrees C.

Parameters

new_temp_threshold

The new high temperature threshold in degrees C. Resolution is 0.5 C

getTemperatureHysteresis()

float Adafruit_PCT2075::getTemperatureHysteresis

(

void

)

Gets the temperature hysteresis value in degrees C.

Returns

The temperature hysteresis value in degrees C. Resolution is 0.5 C

setTemperatureHysteresis()

void Adafruit_PCT2075::setTemperatureHysteresis

(

float

temp_hysteresis

)

Sets the temperature hysteresis value in degrees C.

Parameters

temp_hysteresis

The new high temperature threshold in degrees C. Resolution is 0.5 C

getMode()

pct2075_mode_t Adafruit_PCT2075::getMode

(

void

)

Gets the high temperature alert mode.

Returns

The high temperature alert mode

setMode()

void Adafruit_PCT2075::setMode

(

pct2075_mode_t

mode

)

Sets the high temperature alert mode.

Parameters

mode	The mode to set. Must be a pct2075_mode_t

getFaultCount()

pct2075_fault_count_t Adafruit_PCT2075::getFaultCount

(

void

)

Gets the fault count.

Returns

The pct2075_fault_count_t signifying the number of faults needed to raise an alert.

setFaultCount()

void Adafruit_PCT2075::setFaultCount

(

pct2075_fault_count_t

fault_count

)

Sets the fault count.

Parameters

fault_count

The number of faults needed to raise an alert.
