Function Documentation

◆ LTC_GetState()

LTC_STATEMACH_e LTC_GetState ( LTC_STATE_s * ltc_state )

gets the current state.

This function is used in the functioning of the LTC state machine.

Parameters

ltc_state state of the ltc state machine

Returns: current state, taken from LTC_STATEMACH_e

Definition at line 567 of file ltc_6806.c.

◆ LTC_GetStateRequest()

LTC_REQUEST_s LTC_GetStateRequest ( LTC_STATE_s * ltc_state )

gets the current state request.

This function is used in the functioning of the LTC state machine.

Parameters

ltc_state state of the ltc state machine

Returns: retval current state request, taken from LTC_STATE_REQUEST_e

Definition at line 547 of file ltc_6806.c.

Here is the call graph for this function:

◆ LTC_InitializeMonitoringPin()

void LTC_InitializeMonitoringPin ( void )

Sets the transceiver pins to enable LTC6820 IC.

Definition at line 1752 of file ltc_6806.c.

Here is the call graph for this function:

◆ LTC_IsFirstMeasurementCycleFinished()

bool LTC_IsFirstMeasurementCycleFinished ( LTC_STATE_s * ltc_state )

gets the measurement initialization status.

Parameters

ltc_state state of the ltc state machine

Returns: true if a first measurement cycle was made, false otherwise

Definition at line 1733 of file ltc_6806.c.

Here is the call graph for this function:

◆ LTC_SaveAllGpioMeasurement()

void LTC_SaveAllGpioMeasurement ( LTC_STATE_s * ltc_state )

stores the measured GPIOs in the database.

This function loops through the data of all modules in the LTC daisy-chain that are stored in the ltc_allgpiovoltage buffer and writes them in the database. At each write iteration, the variable named "state" and related to voltages in the database is incremented.

Parameters

ltc_state state of the ltc state machine

Definition at line 506 of file ltc_6806.c.

◆ LTC_SaveTemperatures()

void LTC_SaveTemperatures	(	LTC_STATE_s *	ltc_state,
		uint8_t	stringNumber
	)

stores the measured temperatures and the measured multiplexer feedbacks in the database.

This function loops through the temperature and multiplexer feedback data of all modules in the LTC daisy-chain that are stored in the LTC_MultiplexerVoltages buffer and writes them in the database. At each write iteration, the variables named "state" and related to temperatures and multiplexer feedbacks in the database are incremented.

Parameters

ltc_state	state of the ltc state machine
stringNumber	string addressed

Definition at line 460 of file ltc_6806.c.

Here is the call graph for this function:

◆ LTC_SaveVoltages()

void LTC_SaveVoltages	(	LTC_STATE_s *	ltc_state,
		uint8_t	stringNumber
	)

stores the measured voltages in the database.

This function loops through the data of all modules in the LTC daisy-chain that are stored in the LTC_CellVoltages buffer and writes them in the database. At each write iteration, the variable named "state" and related to voltages in the database is incremented.

Parameters

ltc_state	state of the ltc state machine
stringNumber	string addressed

Definition at line 402 of file ltc_6806.c.

Here is the call graph for this function:

◆ LTC_SetStateRequest()

LTC_RETURN_TYPE_e LTC_SetStateRequest	(	LTC_STATE_s *	ltc_state,
		LTC_REQUEST_s	statereq
	)

sets the current state request of the state variable ltc_state.

This function is used to make a state request to the state machine,e.g, start voltage measurement, read result of voltage measurement, re-initialization It calls LTC_CheckStateRequest() to check if the request is valid. The state request is rejected if is not valid. The result of the check is returned immediately, so that the requester can act in case it made a non-valid state request.

Parameters

ltc_state	state of the ltc state machine
statereq	state request to set

Returns: current state request, taken from LTC_STATE_REQUEST_e

Definition at line 605 of file ltc_6806.c.

Here is the call graph for this function:

◆ LTC_Trigger()

void LTC_Trigger ( LTC_STATE_s * ltc_state )

trigger function for the LTC driver state machine.

This function contains the sequence of events in the LTC state machine. It must be called time-triggered, every 1ms.

Definition at line 620 of file ltc_6806.c.

Here is the call graph for this function:

Variable Documentation
