PyDLT

A pyre-python library to handle AUTOSAR DLT protocol, which is based on AUTOSAR Specification of Diagnostic Log and Trace V1.2.0 R4.0 Rev3, Section 7.7 Protocol Specification.

Quick Start

Write messages to DLT file

from pydlt import (
    ArgumentString,
    DltFileWriter,
    DltMessage,
    MessageLogInfo,
    MessageType,
    StorageHeader,
)

# Create DLT message
msg1 = DltMessage.create_verbose_message(
    [ArgumentString("hello, pydlt!")],
    MessageType.DLT_TYPE_LOG,
    MessageLogInfo.DLT_LOG_INFO,
    "App",
    "Ctx",
    message_counter=0,
    str_header=StorageHeader(0, 0, "Ecu"),
)
print(msg1)
# > 1970/01/01 00:00:00.000000 0 Ecu App Ctx log info verbose 1 hello, pydlt!
msg2 = DltMessage.create_non_verbose_message(
    0,
    b"\x01\x02\x03",
    message_counter=1,
    str_header=StorageHeader(0, 0, "Ecu"),
)
print(msg2)
# > 1970/01/01 00:00:00.000000 1 Ecu non-verbose [0] 010203

# Write DLT messages to file
with DltFileWriter("<path to DLT file>") as writer:
    writer.write_messages([msg1, msg2])

Read messages from DLT file

from pydlt import DltFileReader

# Read DLT messages from file
for msg in DltFileReader("<path to DLT file>"):
    # Print overview of each DLT message
    print(msg)
