Enumerations¶
ChannelData¶
- class canlib.linlib.ChannelData(value)[source]¶
linCHANNELDATA_xxx
These defines are used in
getChannelData
.- CARD_FIRMWARE_REV = 9¶
Firmware version from the LIN interface.
ChannelType¶
- class canlib.linlib.ChannelType(value)[source]¶

The function is only for a slave.
- TIMEOUT = -11¶
Timeout occurred
- VERSION = -24¶
Function not supported in this version
- WRONGRESP = -17¶

MessageDisturb¶
MessageFlag¶
- class canlib.linlib.MessageFlag(value)[source]¶

The following flags is used in
LINFrame.flags
.- BIT_ERROR = 128¶
Bit error when transmitting.
- CSUM_ERROR = 16¶
Checksum error
- NODATA = 8¶
No data, only a header.
- PARITY_ERROR = 32¶
ID parity error
- RX = 2¶
The message was something we received from the bus.
- SYNCH_ERROR = 64¶
A synch error
- SYNC_ERROR = 64¶
A synch error
- TX = 1¶
The message was something we transmitted on the bus.
- WAKEUP_FRAME = 4¶
MessageParity¶
- class canlib.linlib.MessageParity(value)[source]¶
LIN message parity
MessageParity.STANDARD
==LIN_MSG_USE_STANDARD_PARITY
MessageParity.ENHANCED
==LIN_MSG_USE_ENHANCED_PARITY
- ENHANCED = 8¶
Use enhanced (2.x) parity for the specified msg
- STANDARD = 4¶
Use standard (1.x) parity for the specified msg
Setup¶
- class canlib.linlib.Setup(value)[source]¶
Used in
Channel.setupLIN
- ENHANCED_CHECKSUM = 1¶
When specified, the LIN interface will use the “enhanced” checksum according to LIN 2.0. Note that as per the LIN 2.0 spec) the enhanced checksum is not used on the diagnostic frames even if the
Setup.ENHANCED_CHECKSUM
setting is in effect.
- VARIABLE_DLC = 2¶
When specified, turns variable message length on, so the the message length will depend on the message ID.
