class PyJ2534.define.PASSTHRU_MSG(*args, **kwargs)¶

__init__(*args, **kwargs)¶

Initializer.

To initialize a message for transmission, use the optional tx_flags and data keywords to initialize the message.

Otherwise, for a dummy message container to be used for receive functions, initialize with no arguments or keywords.

Parameters

protocol (ProtocolID) – Protocol that is used by this message.
tx_flags (TxFlags) – Flags to be specified when creating a transmit message. Defaults to TxFlags.TX_NORMAL_TRANSMIT
data (bytes) – Raw message byte data.

property TxFlags¶

Timestamp¶: Structure/Union member

DataSize¶: Structure/Union member

ExtraDataIndex¶: Structure/Union member

property Data¶

property ExtraData¶

class PyJ2534.define.SCONFIG¶

NumOfParams¶: Structure/Union member

class PyJ2534.define.SBYTE_ARRAY(byte_arr=b'\x00')¶

__init__(byte_arr=b'\x00')¶

Initializer.

Initialize with a bytes or bytearray.

BytePtr¶: Structure/Union member
