Function Documentation

◆ ILCK_GetState()

ILCK_STATEMACH_e ILCK_GetState ( void )

gets the current state.

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

Returns: current state, taken from ILCK_STATEMACH_e

Definition at line 250 of file interlock.c.

◆ ILCK_SetStateRequest()

ILCK_RETURN_TYPE_e ILCK_SetStateRequest ( ILCK_STATE_REQUEST_e statereq )

sets the current state request of the state variable ilck_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 ILCK_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

Returns: retVal current state request, taken from ILCK_STATE_REQUEST_e

Definition at line 254 of file interlock.c.

Here is the call graph for this function:

◆ ILCK_Trigger()

void ILCK_Trigger ( void )

trigger function for the ILCK driver state machine.

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

Definition at line 268 of file interlock.c.
