ESP32-S3 CAN Car Gauge

@AwaisChaudhry

Hello, I will build a compact, reliable ESP32-S3 CAN gauge that reads six live metrics from the vehicle CAN bus, applies light filtering, and renders them on the Waveshare round display with a clean, toggleable UI. The approach is to use robust CAN decoding for the relevant IDs, organize data in a small, well-commented Arduino/ESP-IDF style project, and provide clear build instructions and assets. The UI will show six values with on/off checkboxes for each, and updates will be smooth thanks to a simple framebuffer and efficient redraws. I will keep the code modular, with separate CAN, UI, and utility layers, plus inline documentation so you can extend or adapt it later. What is the target vehicle, exact CAN IDs, and any specific data formats or filtering requirements to ensure correct decoding and UI updates? Questions I would ask to firm up scope and deliverables: What is the exact list of CAN IDs and their data formats for your vehicle, and are there any particular filtering or averaging windows you prefer? What display resolution and color depth are required for the 2.1/2.8 round boards, and do you have any font or asset constraints? Are there power considerations or electrical constraints I should design around for the ESP32-S3 board and the TJA1051T/3 interface? Do you want units and scaling stored in non-volatile memory to survive resets, or a fresh read on each boot is fine? Is there a preferred build system (Arduino, ESP-IDF, PlatformIO) and any CI steps needed? Do y

Hi there, I’ve worked on ESP32-based CAN dashboards and will tailor a clean, documented solution for the Waveshare ESP32-S3 board with a TJA1051T/3 interface. I’ll implement a compact CAN layer, decode the six target IDs, apply lightweight filtering, and render a legible UI on the color display with a simple on/off toggle for each metric. The deliverables will include well-commented Arduino/ESP-IDF style code and a small set of display assets. Build instructions will cover wiring, libraries, and a ready-to-run project folder so you can compile and flash with minimal steps. What specific CAN IDs and any preferred filtering (e.g., rolling average window) should be applied to each signal to balance responsiveness with noise suppression? Best regards, Marko Aleksic

​Hi, ​Developing a dashboard gauge for a vehicle environment is as much about stability as it is about aesthetics. I have been working with ESP32-S3 and CAN-Bus integration since 2019, and I’m intimately familiar with the Waveshare Round Display series. For a high-end project like this, I don't just "read IDs"—I ensure the data is filtered, the UI is fluid, and the system is safe for automotive use. ​My Professional Approach to your MVP: ​Reliable CAN Infrastructure: I will utilize the ESP32-S3’s native TWAI (Two-Wire Automotive Interface) driver in "Listen-Only" mode. This guarantees that my device will never interfere with your ECU or trigger any dashboard errors. ​High-Fidelity UI (LVGL): I will build the interface using LVGL (v8.3 or v9), specifically optimized for circular screens. You’ll get smooth 60FPS needle animations and high-contrast layouts for maximum legibility while driving. ​Advanced Data Cleaning: Automotive sensor data (especially Boost and Oil Pressure) can be noisy. I will implement a Moving Average Filter to ensure the readouts are steady and professional, without the "flicker" seen in cheaper gauges. ​Modular Features: I’ll include a dedicated settings layer to handle your requirement for toggling the 6 values (Oil Temp, EGT, Water Temp, Oil Pressure, Boost, Lambda/AFR) via a simple checkbox interface. ​Automotive Safety: I will implement a watchdog timer and thermal monitoring to ensure the ESP32 remains stable during long drives and high-temperature dashboard conditions.

Greetings, I recently built a small ESP32-based “ride logger” for a track bike: it listened to CAN frames, did some basic smoothing on noisy sensors, and drew big readable numbers on a small color screen so you could glance fast while riding. That job forced me to get the CAN side stable first, then keep the UI refresh smooth without dropping frames. The main challenge on your gauge is usually not the screen. it’s getting the right CAN IDs / scaling (OEM vs aftermarket ECU, different byte orders, offsets, units) and making the display update cleanly while CAN traffic is busy. My approach would be: bring up ESP32-S3 + TJA1051 and confirm we see frames, implement the 6 signal decoders with filtering, then build the simple UI with per-value on/off toggles. If the CAN IDs + formulas are known and confirmed, I can usually get a first working demo (live numbers on screen) in about 2–3 days, then another 2–4 days to polish toggles, layout, filtering, and code cleanup + build notes. A quick question 1. Do you already have the CAN IDs + scaling for oil temp, EGT, water temp, oil pressure, boost, lambda/AFR? If not, what ECU / vehicle is it, and is it standard OBD-II PIDs or custom CAN frames? Sincerely, Oleksandr

─── ⚡⭐⋆☆⋆⭐⚡ ─── Hi, Client. Hope you are doing well. please review my ESP32, Arduino project review. https://www.freelancer.com/projects/embedded-systems/OTA-Dual-Bank-STM-Update I have been working with ESP32-S3, Arduino or ESP-IDF, automotive CAN TWAI, and small TFT UI libraries for over 5 years. I have solved similar CAN gauge builds that decode multiple IDs, smooth noisy signals, and stay readable on a tiny round display. I understand the main logic of your project: listen on CAN through the TJA1051T/3, decode oil temp EGT water temp oil pressure boost and AFR, then render six live tiles with simple on off toggles. I'll build a clean CAN decode layer with an ID map, add lightweight filtering like EMA plus rate limiting, run a nonblocking UI loop for fast stable refresh, and deliver well commented source with build steps, required graphics assets, and NVS saved checkbox states.

@yaroslavmark

✅ Okay, I got what you want exactly. I am a senior embedded systems engineer with over 10 years of experience, providing ESP32 firmware development, automotive CAN bus integration, and real-time display UI solutions. In my opinion, the cleanest way to approach this is to build a structured CAN decoding layer with configurable ID mapping and lightweight filtering, then separate it from a responsive graphics task running on the ESP32-S3. That way, your six parameters stay smooth and stable on screen without flicker, while still updating in real time from the vehicle bus. This project is very similar to my previous works. I recently built a motorsport auxiliary display using an ESP32 + MCP2515 where I decoded 18 CAN signals at 500 kbps, implemented rolling-average filtering, and rendered gauges on a 240x240 SPI TFT using LVGL. I also developed a diesel tuning monitor that parsed 12 custom CAN IDs, applied scaling formulas for pressure and temperature sensors, and optimized refresh timing to stay under 20 ms loop latency. Via private chatting or meeting, I will provide the creative idea and good tech solution for your project and I want to discuss about the budget and timeline in detail. Best regards. Yaroslav

@Jafferi12

The main challenge with these round Waveshare displays is making sure the UI does not lag while the CAN bus is flooding the ESP32 S3 with data. I am a Computer Engineer and I have done alot of this kinds of the project in my bachelors. I will write the firmware to filter your specific CAN IDs for oil and boost so the display stays very smooth. You will not need to hire another person because I handle the coding and the UI design myself. I will also include a simple PDF guide for the wiring so you can install it without any guesswork. Let us have a quick chat about your vehicle CAN protocol so I can start on the code today.
