Diagnostic Information ¶ Functions for getting diagnostic information about a given CAN Network. GetBaudrate (Function) GetBusAlarm (Function) GetBusState (Function) GetBusload (Function) GetDiagnosis (Function) GetLostCounter (Function) GetReceiveCounter (Function) GetReceiveErrorCounter (Function) GetReceivePoolSize (Function) GetReceiveQueueLength (Function) GetTransmitCounter (Function) GetTransmitErrorCounter (Function) GetTransmitPoolSize (Function) GetTransmitQueueLength (Function) IsSendingActive (Function) ResetBusAlarm (Function)

GetBaudrate (FUN) ¶ FUNCTION GetBaudrate : UINT This function returns the current baudrate of the bus. Information can be also read by GetDiagnosis . InOut: Scope Name Type Comment Return GetBaudrate UINT baudrate in kBit/s Input hDriver CAA.HANDLE handle of CAN interface peError POINTER TO ERROR optional pointer to error enum

GetBusAlarm (FUN) ¶ FUNCTION GetBusAlarm : BOOL This function returns if the CAN chip is in Bus Alarm state. In this state sending and receiving messages is not possible. A Bus Alarm can be reset by ResetBusAlarm which leads to a re-initialization of the CAN chip. Diagnostic Information can be also read by GetDiagnosis . InOut: Scope Name Type Comment Return GetBusAlarm BOOL TRUE if a bus alarm is pending. Input hDriver CAA.HANDLE handle of CAN interface peError POINTER TO ERROR optional pointer to error enum

GetBusState (FUN) ¶ FUNCTION GetBusState : BUSSTATE This function return the current state of the bus. Diagnostic Information can be also read by GetDiagnosis . InOut: Scope Name Type Comment Return GetBusState BUSSTATE current bus state Input hDriver CAA.HANDLE handle of CAN interface peError POINTER TO ERROR optional pointer to error enum

GetBusload (FUN) ¶ FUNCTION GetBusload : USINT This function is not implemented by all drivers. It returns the current busload in percent. Diagnostic Information can be also read by GetDiagnosis . InOut: Scope Name Type Comment Return GetBusload USINT bus load (0..100) in percent Input hDriver CAA.HANDLE handle of CAN interface peError POINTER TO ERROR optional pointer to error enum

GetDiagnosis (FUN) ¶ FUNCTION GetDiagnosis : ERROR Function returns all relevant diagnostic information for a specific driver. InOut: Scope Name Type Comment Return GetDiagnosis ERROR ERROR.NO_ERROR or appropriate error code Input hDriver CAA.HANDLE handle of CAN interface pDiagnosisInfo POINTER TO DIAGNOSIS_INFO Pointer to diagnostic information

GetLostCounter (FUN) ¶ FUNCTION GetLostCounter : CAA.COUNT Returns a counter which is incremented with each lost message. Diagnostic Information can be also read by GetDiagnosis . InOut: Scope Name Type Comment Return GetLostCounter CAA.COUNT number of lost messages Input hDriver CAA.HANDLE handle of CAN interface peError POINTER TO ERROR optional pointer to error enum

GetReceiveCounter (FUN) ¶ FUNCTION GetReceiveCounter : CAA.COUNT Returns a counter which is incremented with each received message. Diagnostic Information can be also read by GetDiagnosis . InOut: Scope Name Type Comment Return GetReceiveCounter CAA.COUNT number of received messages Input hDriver CAA.HANDLE handle of CAN interface peError POINTER TO ERROR optional pointer to error enum
