Electronics engineer
About this Gig
Hello and Welcome!
Building an OBD-II emulator requires more than transmitting CAN frames. It requires a well-structured firmware architecture, correct diagnostic message handling, reliable bus communication, and consistent responses to tester requests.
Whether you need a virtual ECU for a laboratory test bench, a simulated vehicle data source, or a custom diagnostic communication prototype, I can help implement the firmware and communication logic your project requires.
What I Will Provide:
- Custom ESP32 firmware development
- Freematics hardware integration
- CAN bus communication and frame handling
- OBD-II protocol simulation and response logic
- Configurable simulated sensor and PID data
- ECU request and response handling
- CAN message filtering and transmission
- Firmware debugging and troubleshooting
- Clean, organized, editable source code
Why Choose Me?
- Engineering-focused embedded firmware development
- Customized solutions based on your hardware and specifications
- Structured, maintainable, and documented code
Have an automotive diagnostics, virtual ECU, or CAN bus simulation project in mind? message now and Let's Build Your OBD-II Emulator!!!
