I will build a python binary stream and hex log data parser
Embedded Firmware Engineer ESP32, STM32, AVR and Hardware Debugging
I am an Embedded Firmware Engineer specializing in C/C++, FreeRTOS, and industrial communication protocols. I don't just write application-level code; I work directly with the bare-metal registers and...
About this Gig
Stop guessing what your microcontroller logs mean. I will build a highly optimized, custom Python Protocol Parsing & Telemetry Diagnostic Tool to turn complex binary streams, proprietary packets, and raw hex dumps into clean JSON, CSV, or structured data.
Microcontrollers squeeze data down to the bit level. I use strong algorithmic structures to reverse-engineer and decode these streams cleanly without memory bloat.
Core Technical Features:
- Bit-Perfect Parsing: Masterful bit-masking, bit-shifting, sign extensions, and Endianness management.
- Stream Integrity: Verification loops handling custom checksums, parity, and CRC-8/16/32 algorithms.
- Math Filtering: Signal cleaning using digital low-pass windows or moving averages to remove sensor outliers.
- Edge-Case Stability: Advanced frame boundary isolation prevents script crashes from corrupted packets.
What you receive: Clean, modular Python source code, complete documentation detailing data structures, and execution templates.
NOTE: Client must provide packet payload definitions or example hex files with expected outputs. Message me first to review your file layout!

FAQ
Can your script process massive multi-gigabyte text files without running out of RAM?
Yes. The code avoids reading massive files into memory all at once. I implement generator functions and chunk-based streaming pipelines, allowing the script to effortlessly step through huge log dumps while maintaining a tiny, consistent RAM footprint.
What if I don't know the exact protocol format, but only have the firmware source code?
If the protocol layout isn't fully documented, you can share the serialization code or the struct serialization block from your MCU firmware (C/C++). I can analyze the firmware configuration to accurately recreate the exact mirror unpacking logic in Python.
