CanGetCanFdTiming

Function

Get the CAN FD communication timing settings.

Format

Ret = CanGetCanTiming ( Id , ChannelNo , ArbBitrate , ArbTSeg1 , ArbSJW , ArbTSeg2 , DataBitrate , DataSeg1 , DataSJW , DataSeg2 )

Parameters

Id [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the device ID retrieved from CanInit.

ChannelNo [ VB.NET: UShort ] [ C, C++: unsigned short ] [ C#: ushort ] [ Python: ctypes.c_ushort ]
Specify the channel number.

ArbBitrate [ VB.NET: UInteger ] [ C, C++: unsigned long * ] [ C#: out uint ] [ Python: ctypes.POINTER(ctypes.c_uint) ]
Get the arbitration bitrate. The unit is bps. (bit per second)

ArbTSeg1 [ VB.NET: UShort ] [ C, C++: unsigned short * ] [ C#: out ushort ] [ Python: ctypes.POINTER(ctypes.c_ushort) ]
Get the arbitration time segment 1. The unit is TQ.

ArbSJW [ VB.NET: UShort ] [ C, C++: unsigned short * ] [ C#: out ushort ] [ Python: ctypes.POINTER(ctypes.c_ushort) ]
Get the arbitration SJW. The unit is TQ.

ArbTSeg2 [ VB.NET: UShort ] [ C, C++: unsigned short * ] [ C#: out ushort ] [ Python: ctypes.POINTER(ctypes.c_ushort) ]
Get the arbitration time segment 2. The unit is TQ.

DataBitrate [ VB.NET: UInteger ] [ C, C++: unsigned long * ] [ C#: out uint ] [ Python: ctypes.POINTER(ctypes.c_uint) ]
Get the data bitrate. The unit is bps. (bit per second)

DataTSeg1 [ VB.NET: UShort ] [ C, C++: unsigned short * ] [ C#: out ushort ] [ Python: ctypes.POINTER(ctypes.c_ushort) ]
Get the data time segment 1. The unit is TQ.

DataSJW [ VB.NET: UShort ] [ C, C++: unsigned short * ] [ C#: out ushort ] [ Python: ctypes.POINTER(ctypes.c_ushort) ]
Get the data SJW. The unit is TQ.

DataTSeg2 [ VB.NET: UShort ] [ C, C++: unsigned short * ] [ C#: out ushort ] [ Python: ctypes.POINTER(ctypes.c_ushort) ]
Get the data time segment 2. The unit is TQ.

Return Value

Ret [ VB.NET: Integer ] [ C, C++: long ] [ C#: int ] [ Python: ctypes.c_long ]

Initial Value

None

Remarks

Get the CAN FD communication timing settings.
It can be used even when connected to CAN bus.

For details, please refer to CAN communication transmission time.

Example

Get ArbBitrate, ArbTSeg1, ArbSJW, ArbTSeg2, DataBitrate, DataTSeg1, DataSJW, DataTSeg2 set to ChannelNo = 1.
