Member Function Documentation

◆ debug_data()

void esphome::opentherm::OpenTherm::debug_data ( OpenthermData & data )

◆ debug_error()

void esphome::opentherm::OpenTherm::debug_error ( OpenThermError & error ) const

◆ esp8266_timer_isr()

◆ get_message()

bool esphome::opentherm::OpenTherm::get_message ( OpenthermData & data )

Use this to retrive data packed captured by listen() function.

Data packet is ready when has_message() function returns true. This function can be called multiple times until stop() is called.

Parameters

data	reference to data structure to which fill the data packet data.

Returns: true if packet was ready and was filled into data structure passed, false otherwise.

◆ get_mode()

OperationMode esphome::opentherm::OpenTherm::get_mode ( )

inline

Definition at line 335 of file opentherm.h.

◆ get_protocol_error()

bool esphome::opentherm::OpenTherm::get_protocol_error ( OpenThermError & error )

Get protocol error details in case a protocol error occured.

Parameters

error reference to data structure to which fill the error details

Returns: true if protocol error occured during last conversation, false otherwise.

◆ has_message()

bool esphome::opentherm::OpenTherm::has_message ( )

inline

Use this function to check whether listen() function already captured a valid data packet.

Returns: true if data packet has been captured from line by listen() function.

Definition at line 257 of file opentherm.h.

◆ initialize()

bool esphome::opentherm::OpenTherm::initialize ( )

Setup pins.

◆ is_active()

bool esphome::opentherm::OpenTherm::is_active ( )

inline

Definition at line 333 of file opentherm.h.

◆ is_error()

bool esphome::opentherm::OpenTherm::is_error ( )

inline

Indicates whether last listen() or send() operation ends up with an error.

Includes both timeout and protocol errors.

Returns: true if last listen() or send() operation ends up with an error.

Definition at line 311 of file opentherm.h.

◆ is_idle()

bool esphome::opentherm::OpenTherm::is_idle ( )

inline

Indicates whether listinig or sending is not in progress.

That also means that no timers are running and no interrupts are attached.

Returns: true if listening nor sending is in progress.

Definition at line 303 of file opentherm.h.

◆ is_protocol_error()

bool esphome::opentherm::OpenTherm::is_protocol_error ( )

inline

Indicates whether last listen() or send() operation ends up with a protocol error.

Returns: true if last listen() or send() operation ends up with a protocol error.

Definition at line 325 of file opentherm.h.

◆ is_sent()

bool esphome::opentherm::OpenTherm::is_sent ( )

inline

Use this function to check whether send() function already finished sending data packed to line.

Returns: true if data packet has been sent, false otherwise.

Definition at line 295 of file opentherm.h.

◆ is_timeout()

bool esphome::opentherm::OpenTherm::is_timeout ( )

inline

Indicates whether last listen() or send() operation ends up with a timeout error.

Returns: true if last listen() or send() operation ends up with a timeout error.

Definition at line 319 of file opentherm.h.

◆ is_timer_error()

bool esphome::opentherm::OpenTherm::is_timer_error ( )

inline

Indicates whether start_esp32_timer_() or stop_timer_() had an error.

Only relevant when used on ESP32.

Returns: true if there was an error.

Definition at line 331 of file opentherm.h.

◆ listen()

void esphome::opentherm::OpenTherm::listen ( )

Start listening for Opentherm data packet comming from line connected to given pin.

If data packet is received then has_message() function returns true and data packet can be retrieved by calling get_message() function. If timeout > 0 then this function waits for incomming data package for timeout millis and if no data packet is recevived, error state is indicated by is_error() function. If either data packet is received or timeout is reached listening is stopped.

◆ message_id_to_str()

const char * esphome::opentherm::OpenTherm::message_id_to_str ( MessageId id )

◆ message_type_to_str()

const char * esphome::opentherm::OpenTherm::message_type_to_str ( MessageType message_type )

◆ operation_mode_to_str()

const char * esphome::opentherm::OpenTherm::operation_mode_to_str ( OperationMode mode )

◆ protocol_error_to_str()

const char * esphome::opentherm::OpenTherm::protocol_error_to_str ( ProtocolErrorType error_type )

◆ report_and_reset_timer_error()

void esphome::opentherm::OpenTherm::report_and_reset_timer_error ( )

◆ send()

void esphome::opentherm::OpenTherm::send ( OpenthermData & data )

Immediately send out Opentherm data packet to line connected on given pin.

Completed data transfer is indicated by is_sent() function. Error state is indicated by is_error() function.

Parameters

data	Opentherm data packet.

◆ stop()

void esphome::opentherm::OpenTherm::stop ( )

Stops listening for data packet or sending out data packet and resets internal state of this class.

Stops all timers and unattaches all interrupts.

◆ timer_error_to_str()

const char * esphome::opentherm::OpenTherm::timer_error_to_str ( TimerErrorType error_type )

◆ timer_isr() [1/2]

static bool esphome::opentherm::OpenTherm::timer_isr	(	gptimer_handle_t	timer,
		const gptimer_alarm_event_data_t *	edata,
		void *	user_ctx )

static

◆ timer_isr() [2/2]
