Member Function Documentation

bit_op16()

void P3T2030::bit_op16	(	uint8_t	reg,
		uint16_t	mask,
		uint16_t	value )

bit_op8()

void P3T2030::bit_op8	(	uint8_t	reg,
		uint8_t	mask,
		uint8_t	value )

Register overwriting with bit-mask

Register can be updated by bit level

Parameters

reg	register index/address/pointer
mask	bit-mask to protect overwriting
value	value to overwrite

os_mode()

virtual void P3T2030::os_mode ( mode flag )

virtual

Set OS operation mode

This is dummy method since P3T2030 doesn't have the thermostat mode

Parameters

flag	use P3T2030::COMPARATOR or P3T1755::INTERRUPT values

Reimplemented from P3T1035.

ping()

bool P3T2030::ping

(

void

)

Ping the device

Returns

true when ACK

read()

virtual float P3T2030::read ( void )

virtual

Get temperature value in degree Celsius [°C]

This method simply calls "temp()" method

Returns

temperature value in degree Celsius [°C]

Reimplemented from P3T1035.

read_r16()

uint16_t P3T2030::read_r16

(

uint8_t

reg

)

Register read, 16 bit

This 16 bit access may ot be common but it's useful for sensor devices

Parameters

reg	register index/address/pointer

Returns

data value

read_r8()

uint8_t P3T2030::read_r8

(

uint8_t

reg

)

Register read, 8 bit

Parameters

reg	register index/address/pointer

Returns

data value

temp()

virtual float P3T2030::temp ( void )

virtual

Get temperature value in degree Celsius [°C]

Returns

temperature value in degree Celsius [°C]

Reimplemented from P3T1035.

thresholds()

virtual void P3T2030::thresholds ( float v0, float v1 )

overridevirtual

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

Reimplemented from P3T1035.

write_r16()

void P3T2030::write_r16	(	uint8_t	reg,
		uint16_t	val )

Register write, 16 bit

This 16 bit access may ot be common but it's useful for sensor devices

Parameters

reg	register index/address/pointer
val	data value

write_r8()

void P3T2030::write_r8	(	uint8_t	reg,
		uint8_t	val )

Register write, 8 bit

Parameters

reg	register index/address/pointer
val	data value
