MessageDisturb

class canlib.linlib.MessageDisturb(value)[source]

LIN illegal message flags

CSUM = 1

The checksum of transmitted messages will be inverted

PARITY = 2

The two parity bits will be inverted, used only in master mode.

MessageFlag

class canlib.linlib.MessageFlag(value)[source]

LIN message flags

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

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.
