Function Documentation

SPS_Ctrl()

void SPS_Ctrl

(

void

)

Control function for the CONT driver state machine.

This function contains the sequence of events in the SPS state machine. It must be called time-triggered, every 10ms. It exits without effect, if the function call is a reentrance.

Definition at line 475 of file sps.c.

Here is the call graph for this function:

SPS_GetChannelAffiliation()

SPS_CHANNEL_AFFILIATION_e SPS_GetChannelAffiliation

(

SPS_CHANNEL_INDEX

channelIndex

)

Returns the channel affiliation.

Parameters

[in]

channelIndex

index of the channel in question

Returns

affiliation of the channel

Definition at line 645 of file sps.c.

SPS_GetChannelCurrentFeedback()

CONT_ELECTRICAL_STATE_TYPE_e SPS_GetChannelCurrentFeedback

(

const SPS_CHANNEL_INDEX

channelIndex

)

Get feedback value.

This function compares the measured current in the contactor channel with a fixed threshold and assumes the contactor feedback to be closed when this threshold is passed on the channel.

Parameters

[in]

channelIndex

index of the channel (contactor) that should be accessed

Returns

state of the channel's feedback

Definition at line 606 of file sps.c.

Here is the call graph for this function:

SPS_GetChannelPexFeedback()

CONT_ELECTRICAL_STATE_TYPE_e SPS_GetChannelPexFeedback	(	const SPS_CHANNEL_INDEX	channelIndex,
		bool	normallyOpen
	)

Get the feedback state of a channel.

Retrieves the feedback state of a sps channel by looking up the appropriate channel in sps_kChannelFeedbackMapping and retrieving the value through the PEX API.

Parameters

[in]	channelIndex	number of the SPS channel that shall be checked
[in]	normallyOpen	true if the feedback is normally open, false if not

Returns

state of the channel as reported by PEX

Definition at line 622 of file sps.c.

Here is the call graph for this function:

SPS_Initialize()

void SPS_Initialize

(

void

)

Initialize IOs for the SPS driver.

This function sets the necessary register (e.g., configure pins as input or output).

Definition at line 592 of file sps.c.

Here is the call graph for this function:

SPS_RequestContactorState()

void SPS_RequestContactorState	(	SPS_CHANNEL_INDEX	channelIndex,
		SPS_CHANNEL_FUNCTION_e	channelFunction
	)

Request state of a contactor.

This function checks if the requested channel is affiliated to contactors and then passes the arguments on to SPS_RequestChannelState().

Parameters

[in]	channelIndex	number of the channel that should be accessed; This has to be a SPS channel and it has to be affiliated with SPS_AFF_CONTACTOR
[in]	channelFunction	requested functional state of the channel

Definition at line 596 of file sps.c.

Here is the call graph for this function:

SPS_RequestGeneralIOState()

void SPS_RequestGeneralIOState	(	SPS_CHANNEL_INDEX	channelIndex,
		SPS_CHANNEL_FUNCTION_e	channelFunction
	)

Request state of a general IO.

This function checks if the requested channel is affiliated to general IO and then passes the arguments on to SPS_RequestChannelState().

Parameters

[in]	channelIndex	number of the channel that should be accessed; This has to be a SPS channel and it has to be affiliated with SPS_AFF_GENERAL_IO
[in]	channelFunction	requested functional state of the channel
