Module-prefix LTC

Function Documentation

◆ LTC_GetMuxSequenceState()

STD_RETURN_TYPE_e LTC_GetMuxSequenceState ( void )

gets the measurement initialization status.

Returns: retval TRUE if a first measurement cycle was made, FALSE otherwise

◆ LTC_GetState()

LTC_STATEMACH_e LTC_GetState ( void )

gets the current state.

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

Returns: current state, taken from LTC_STATEMACH_e

◆ LTC_GetStateRequest()

LTC_STATE_REQUEST_e LTC_GetStateRequest ( void )

gets the current state request.

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

Returns: retval current state request, taken from LTC_STATE_REQUEST_e

Here is the call graph for this function:

◆ LTC_IsFirstMeasurementCycleFinished()

uint8_t LTC_IsFirstMeasurementCycleFinished ( void )

gets the measurement initialization status.

Returns: retval TRUE if a first measurement cycle was made, FALSE otherwise

Here is the call graph for this function:

◆ LTC_SaveAllGPIOMeasurement()

void LTC_SaveAllGPIOMeasurement ( void )

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.

Here is the call graph for this function:

◆ LTC_SaveAllGPIOs()

void LTC_SaveAllGPIOs ( void )

◆ LTC_SaveTemperatures()

void LTC_SaveTemperatures ( void )

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.

Here is the call graph for this function:

◆ LTC_SaveVoltages()

void LTC_SaveVoltages ( void )

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.

Here is the call graph for this function:

◆ LTC_SetFirstMeasurementCycleFinished()

void LTC_SetFirstMeasurementCycleFinished ( void )

sets the measurement initialization status.

Returns: none

Here is the call graph for this function:

◆ LTC_SetStateRequest()

LTC_RETURN_TYPE_e LTC_SetStateRequest ( LTC_STATE_REQUEST_e 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

statereq	state request to set
adcModereq	LTC ADCmeasurement mode (fast, normal or filtered)
adcMeasChreq	number of channels measured for GPIOS (one at a time for multiplexers or all five GPIOs)
numberOfMeasuredMux	number of multiplexer inputs measured between two cell voltage measurements

Returns: retVal current state request, taken from LTC_STATE_REQUEST_e

Here is the call graph for this function:

◆ LTC_Trigger()

void LTC_Trigger ( void )

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.

Here is the call graph for this function:
