About this Gig
Hello and Welcome!
OBD-II communication is more than reading a few CAN frames a reliable emulator requires correct protocol behavior, timing, message handling, and hardware-level integration.
Whether you need to simulate an ECU, generate realistic OBD-II responses, test a diagnostic application, or build a CAN-based automotive prototype, I can design the firmware architecture around your required PIDs, CAN frames, communication flow, and hardware setup.
What I Will Provide:
- Custom ESP32 OBD-II emulator firmware
- CAN Bus communication implementation
- OBD-II request/response handling
- Standard PID simulation
- Custom PID implementation
- CAN frame generation and parsing
- ECU/vehicle data simulation
- Configurable RPM, speed, coolant temperature, engine load, fuel data, etc.
- Diagnostic communication logic
Why Choose Me?
- Automotive + Embedded Focus
- Custom Firmware Architecture
- CAN Bus Expertise
- ESP32-Based Development
- Debuggable & Maintainable Code
Message me today and let's turn your ESP32 + CAN hardware into a reliable, test-ready OBD-II emulator!!!

FAQ
What hardware can you develop the firmware for?
I can develop firmware for ESP32 boards with compatible CAN transceivers and automotive CAN interfaces.
Can you create a complete OBD-II emulator?
Yes. I can develop custom OBD-II request/response logic, PID simulation, CAN communication, and ECU-style data emulation.
Can you simulate custom OBD-II PIDs?
Yes. I can implement both standard OBD-II PIDs and custom PID responses based on your requirements.
Can you work with FreeMatics?
Yes. I can integrate the firmware with FreeMatics-based automotive data logging and communication requirements.
Can you generate custom CAN frames?
Yes. I can implement configurable CAN IDs, payloads, timing, periodic messages, and event-based CAN transmissions.
