(

const uint8_t

i2c_address = (0x90 >> 1)

)

Create a PCT2075 instance connected to specified I2C pins with specified address

Parameters

i2c_address

I2C-bus address (default: (0x90>>1))

Definition at line 5 of file test_LM75B.cpp.

test_LM75B() [2/2]

test_LM75B::test_LM75B	(	TwoWire &	wire,
		const uint8_t	i2c_address = (0x90 >> 1) )

Create a PCT2075 instance connected to specified I2C pins with specified address

Parameters

wire	TwoWire instance
i2c_address	I2C-bus address (default: (0x90>>1))

Definition at line 9 of file test_LM75B.cpp.

~test_LM75B()

test_LM75B::~test_LM75B

(

)

Destructor of PCT2075

Definition at line 13 of file test_LM75B.cpp.

Member Function Documentation

os_mode()

void test_LM75B::os_mode

(

const mode

flag

)

Set OS operation mode

Parameters

flag	use PCT2075::COMPARATOR or PCT2075::INTERRUPT values

Definition at line 31 of file test_LM75B.cpp.

read()

float test_LM75B::read

(

void

)

Get temperature value in degree Celsius [°C]

Returns

temperature value in degree Celsius [°C]

Definition at line 17 of file test_LM75B.cpp.

thresholds()

void test_LM75B::thresholds	(	const float	v0,
		const float	v1 )

Set Overtemperature shutdown threshold (Tos) and hysteresis (Thyst) in degree Celsius [°C]

This method takes 2 values and higher value will set as the threshold (Tos) and . another will be the hysteresis (Thyst)

Parameters

v0	a value in degree Celsius
v1	a value in degree Celsius
