Detailed Description

Class for handling detailed Hitachi 15to27-byte/120to216-bit A/C messages.

Constructor & Destructor Documentation

IRHitachiAc3()

IRHitachiAc3::IRHitachiAc3 ( const uint16_t  pin, const bool  inverted = false, const bool  use_modulation = true  )

explicit

Class constructor.

Parameters

[in]	pin	GPIO to be used when sending.
[in]	inverted	Is the output signal to be inverted?
[in]	use_modulation	Is frequency modulation to be used?

Member Function Documentation

begin()

void IRHitachiAc3::begin

(

void

)

Set up hardware to be able to send a message.

calibrate()

int8_t IRHitachiAc3::calibrate ( void  )

inline

Run the calibration to calculate uSec timing offsets for this platform.

Returns

The uSec timing offset needed per modulation of the IR Led.

Note

This will produce a 65ms IR signal pulse at 38kHz. Only ever needs to be run once per object instantiation, if at all.

getMode()

uint8_t IRHitachiAc3::getMode

(

void

)

getRaw()

uint8_t * IRHitachiAc3::getRaw

(

void

)

Get a PTR to the internal state/code for this protocol.

Returns

PTR to a code for this protocol based on the current internal state.

hasInvertedStates()

bool IRHitachiAc3::hasInvertedStates ( const uint8_t  state[], const uint16_t  length  )

static

Check if every second byte of the state, after the fixed header is inverted to the previous byte.

Parameters

[in]	state	The state array to be checked.
[in]	length	The size of the state array.

Note

This is this protocols integrity check.

send()

void IRHitachiAc3::send

(

const uint16_t

repeat = kHitachiAcDefaultRepeat

)

setInvertedStates()

void IRHitachiAc3::setInvertedStates ( const uint16_t  length = kHitachiAc3StateLength )

private

Invert every second byte of the internal state, after the fixed header.

Parameters

[in]

length

The size of the state array.

Note

This is this protocols integrity check.

setRaw()

void IRHitachiAc3::setRaw	(	const uint8_t	new_code[],
		const uint16_t	length = kHitachiAc3StateLength
	)

Set the internal state from a valid code for this protocol.

Parameters

[in]	new_code	A valid code for this protocol.
[in]	length	The length of the new_code array.

stateReset()

void IRHitachiAc3::stateReset

(

void

)

Reset the internal state to a fixed known good state.

Note

Reset to auto fan, cooling, 23° Celsius

Member Data Documentation

_irsend

IRsend IRHitachiAc3::_irsend

private

Instance of the IR send class.

remote_state

uint8_t IRHitachiAc3::remote_state[kHitachiAc3StateLength]

private

The state in native code.
