The dltreader Python module allows the reading of AUTOSAR ["Diagnostic, Log and Trace Protocol"](https://www.autosar.org/fileadmin/standards/foundation/1-0/AUTOSAR_PRS_DiagnosticLogAndTraceProtocol.pdf) files. files.
The goal of this module is to provide a simple, purely Python-based module to read .dlt files without further dependencies. Apart from that a permissive free software license shall is supported to make it usable in possible commercial contexts.
pip install -U dltreader
from dlt import DltReader
with DltReader("example.dlt") as r:
for storage_header, packet in r:
if not packet.has_payload():
# skip packets that do not have a payload
continue
print(packet)
At current point in time the module is a PoC so should not be used in production software; besides, it is only a partial implementation of the overall standard and not optimized for performance.
Please check the docs/ directory for further details.
