CANSIG_DATA

Description

This structure contains the current status informations for a signal.

Members

typedef struct {
 CPU_INT16U    Id;
 CPU_INT08U    Status;
 CANSIG_VAL_T  Value;
 CPU_INT32U    TimeStamp;
 CANSIG_PARA  *Cfg;
 void         *Next;
} CANSIG_DATA;

Member	Meaning
`Id`	The unique signal identifier.
`Status`	The current status of the signal.
`Value`	The current value of the signal. Note: The type of the value `CANSIG_VAL_T` depends on the configuration setting `CANSIG_MAX_WIDTH`
`TimeStamp`	Timestamp of last received signal. Note: The signal will be timestamped when a message is written to the signal layer with function CanMsgWrite(..). The time for the timestamp is received from a timer of the underlying OS and therefore has the resolution of the OS timer.
`Cfg`	The pointer to the corresponding CAN signal parameters.
`Next`	The pointer to the next signal in the signal list.

Additional Information

Status	Meaning
`CANSIG_UNUSED`	This define holds the coding for the information: 'signal not used'. This status is the default status, before the CAN signal initialization function is called. After the CAN signal initialization, this status remains in the CAN signal interface slots, which is not configured via the configuration structure.
`CANSIG_UNCHANGED`	This define holds the coding for the information: 'signal is unchanged'. This status will be set, after a signal access with `CanSigRead()`.
`CANSIG_UPDATED`	This define holds the coding for the information: 'signal is updated'. This status will be set, after a signal write access with `CanSigWrite()` - independent from the signal value.
`CANSIG_CHANGED`	This define holds the coding for the information: 'signal is changed'. This status will be set, when a `CanSigWrite()` access changes the value of the signal.
`CANSIG_ERROR`	This define holds the coding for the information: 'signal error'.
