CanGetCanTiming

Function

Get the CAN communication timing settings.

Format

Ret = CanGetCanTiming ( Id , ChannelNo , Bitrate , TSeg1 , SJW , TSeg2 )

Parameters

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

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

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

TSeg1 [ VB.NET: UShort ] [ C, C++: unsigned short * ] [ C#: out ushort ]
Get the time segment 1. The unit is TQ.

SJW [ VB.NET: UShort ] [ C, C++: unsigned short * ] [ C#: out ushort ]
Get the SJW. The unit is TQ.

TSeg2 [ VB.NET: UShort ] [ C, C++: unsigned short * ] [ C#: out ushort ]
Get the time segment 2. The unit is TQ.

Return Value

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

Definition	Value [Dec]	Description
CAN_ERR_SUCCESS	0	Normality completion
CAN_ERR_SYS_RECOVERED_FROM_STANDBY	7	Execute CanResetDevice function because the device has recovered from standby mode.
CAN_ERR_DLL_INVALID_ID	10001	Invalid ID specified.
CAN_ERR_DLL_CALL_DRIVER	10002	Driver can't be called (Failed in the device I/O control).
CAN_ERR_DLL_BUFF_ADDRESS	10100	Invalid data buffer address.
CAN_ERR_SYS_CH_NO	20101	Channel number is outside the settable range

The others (See also: Details of Error Code)

Initial Value

None

Remarks

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

For details, please refer to CAN communication transmission time.

Example

Get Bitrate, TSeg1, SJW, TSeg2 set to ChannelNo = 1.
