ESP32 CAN-Bus Hex Control

@amelectronics

Hi, I have experience in designing Circuits and can complete your project. I have expertise in the following: 1- Designing schematic and PCBA 2- Ordering the PCBA and getting boards manufactured. 3- Writing firmware for the PCBA to make sure everything works as expected. 4- I can also develop smartphone apps to communicate and control the hardware. If you wish we can discuss in chat. Thank you.

I have done multiple CAN projects using arduino framework. Let's discuss. Please send me your setup details

Hi, I can develop the ESP32 CAN-Bus firmware to receive, decode, process, and transmit CAN frames according to your supplied HEX files and CAN command tables. Proposed Approach: Configure ESP32 CAN communication using ESP-IDF/Arduino-ESP32. Decode incoming CAN IDs, bytes, and bitfields. Convert HEX data into meaningful decimal parameters. Update internal variables and generate required status frames. Add out-of-range detection and Serial Monitor diagnostics. Test live CAN traffic with the PCAN tracer. Deliverables: ESP32 CAN firmware source code CAN/HEX decoding logic CAN ID and byte mapping table Status frame transmission Build instructions Testing log/video

I will write the firmware that makes your ESP32 AAP/AAD modules talk CAN-Bus in real time. Parse incoming hex frames, decode bitfields to decimal, update internal variables, and transmit status frames back — all within 20ms. What I Will Deliver: Firmware (ESP-IDF 5.x compatible): Imports your supplied HEX files and calibration tables Decodes incoming CAN frames → translates each to decimal parameters Updates internal variables → transmits required status frames Serial console prints any out-of-range value for troubleshooting Runs continuously for 8 hours without missed frames Documentation: Concise table mapping every CAN ID + byte offset → decoded value (for cross-check with your Peak-PCAN tracer) Build instructions Short video/log file showing live traffic tests on hardware Tech: ESP-IDF 5.x + TWAI (CAN) driver. Compatible with your ESP32-CAN dev board and Peak-PCAN tracer. Timeline: 3-5 days Guarantee: 8-hour continuous run, <20ms echo, serial range alerts. You test before final payment. Ready to start. Share your HEX files and CAN command tables.

Hey! I can help you with 'ESP32 CAN-Bus Hex Control'. I have extensive experience working with Embedded Systems & Firmware (ESP32, STM32, C/C++), IoT & Communications (MQTT, WebSockets, REST APIs), Python & Node.js Backend & API Integrations, and I've built similar reliable systems before. This should be straightforward to complete for you. Let me know if you'd like to discuss the details!

Hi, We can handle this project end-to-end using ESP-IDF 5.x and your existing ESP32-CAN hardware. Our scope can include: - CAN frame reception and low-latency processing - Exact HEX/bitfield decoding and decimal parameter mapping - CAN ID / byte-offset documentation table - Internal state update and required status-frame transmission - Out-of-range monitoring and serial diagnostics - Integration with your existing calibration/HEX tables - PCAN-based validation and continuous traffic testing - Build instructions and test evidence We would first review your CAN command table, HEX/calibration files, and sample PCAN traces to confirm frame structure and timing requirements. Because the acceptance criteria include 8-hour stability and sub-20 ms response, this requires proper bench validation rather than only writing code. Magen Daniel Systems LLP specializes in embedded firmware, PCB systems, IoT devices, communication protocols, and prototype development. Please share the CAN database/table, ESP32-CAN board model, and sample trace so we can confirm the exact scope and schedule.

I can start right now I have checked the details. I see you need the ESP32 AAP / AAD firmware to parse hex payloads, unpack bitfields to decimal parameters, and publish status frames back on the bus under 20 ms, using ESP-IDF 5.x alongside your Peak-PCAN setup and hardware. I will deliver the documented source code, the CAN ID/byte offset mapping table, and the validation log. I have one question: are you using the TWAI driver natively in ESP-IDF 5.x for the CAN interface, or an external SPI controller like the MCP2515? lets do it

Hi — CS + electronics, ESP32 bench (soldering station, meter, CAN-capable modules). M1 = review wiring/bitrate + send/receive hex frames on a bench bus (no vehicle risk). M2 = control path as scoped. Share transceiver type / sample frames for a fixed quote or $35/hr. Ukraine remote (Kyiv).

Hi, I can develop the ESP32 CAN firmware using ESP-IDF 5.x, with reliable real-time frame decoding and status transmission. I’ll deliver documented source code, CAN ID/byte mapping tables, range validation, <20 ms response handling, build instructions, and live-test logs. I’ll also optimize buffering and task handling for continuous 8-hour operation. Please share the HEX files, CAN command tables, and a few PCAN trace samples so I can implement the exact protocol.

@sadamhu

Hi, I can develop the ESP32 CAN firmware to communicate with your existing equipment, decode the supplied CAN frames and HEX command tables, update internal parameters, and transmit the required status frames back over the bus. I have experience with ESP32/embedded C/C++, byte-level protocol parsing, hardware communication, and real-time firmware. I can implement the CAN receive/transmit layer, correct byte ordering and bit-field extraction, scaling and decimal conversion, range checking, and low-latency status reporting. I will keep the firmware non-blocking and structured for continuous operation, with CAN error handling and serial diagnostics. I will also provide a clear CAN mapping table showing CAN ID, byte/bit position, decoded parameter, scaling, and units. For validation, I can use your PCAN tracer logs to cross-check the ESP32 decoded values and transmitted frames. The firmware will be targeted to meet the 20 ms response requirement and will be structured for the requested 8-hour continuous test. Please provide the CAN command tables, HEX files, bitrate, and a sample PCAN traffic log so I can verify the protocol before implementing the final parser.

Hi, I have strong hands-on experience developing low-latency CAN-Bus communication drivers and telemetry systems using ESP32 (TWAI peripheral) and microcontrollers in C/C++. Here is my implementation plan for your bench setup: • Hex & Bitfield Parsing: Efficiently decode incoming CAN frames from your command tables into engineering/decimal units using bitmasking, bitshifts, and lightweight lookup structures without blocking tasks. • Bidirectional Low-Latency Control: Implement real-time status frame transmission responding well within your 20ms timing constraint. • Robust Error & Out-of-Range Handling: Add validation layers to catch malformed payloads or out-of-bounds parameters and log them cleanly to the serial console. • Architecture & Compatibility: Develop the firmware compatible with ESP-IDF 5.x / Arduino-ESP32, keeping execution stable for continuous multi-hour runs without frame drops. • Clear Deliverables: Provide fully commented source code, complete mapping documentation (CAN ID & byte offset cross-check table matching your PCAN tracer), and step-by-step flashing/testing instructions. I am ready to review your CAN command tables and HEX files to get started immediately. Best regards, Elif
