Arduino Script for ESP32 UI

@amelectronics

Hi, I can help you complete this project. I have experience with ESP32, Arduino IDE, LVGL, and custom embedded firmware. I'll integrate your SquareLine UI with the ESP32-CYD, connect the RTD sensors, battery monitoring, and implement all settings with NVS so they persist after reboot. I'll also provide clean, well-commented code, build instructions, and all required files to ensure everything compiles and runs smoothly. Looking forward to working with you. Thanks!

Hi there, I read your offer carefully and understand that you already have the SquareLine two-screen UI for an ESP32-CYD nervoscope, and now need Arduino IDE firmware to connect the UI, LVGL/display driver, RTD readings, battery percentage, gauge needle behavior, and persistent settings. I can develop the clean `.ino` sketch, integrate the SquareLine export with LVGL, read both RTD probes, compare temperatures, control the gauge needle, read battery voltage through ADC, implement the settings screen, save preferences in NVS, and provide a concise README with build and flashing steps. My experience with ESP32 firmware, Arduino IDE, LVGL/SquareLine UI integration, sensors, ADC battery monitoring, embedded C/C++, and reliable user-interface logic fits this project well. Just send me a message and we can review the SquareLine project files, RTD interface, and ESP32-CYD display setup. Best regards, Samuel Tshibangu

Hi We could export UI file from Squareline Studio UI, set up Arduino IDE with dependencies like LVGL and TFT_eSPI, and set up the code. I could test the code right now if you could give me the specifications of the device and the sensors too. To find a common ground please answer the questions below: 1) Which LVGL and SquareLine versions were used to create the existing UI? 2) Which ADC pin and voltage divider values are used for battery values? 3) Should settings be saved using Preferences/NVS only, or also exported in a config file? I’m happy to discuss the details over chat, and I will respond promptly. Thanks for your attention Archil

Finished Squareline UI with all events set — that's exactly where I like to pick up. I'll take your project, wire it to LVGL, and give you a .ino that runs exactly as designed, no guesswork. Here's what I bring to this: → I've shipped multiple ESP32-CYD projects, and I know the quirks of that display and touch setup cold → I'll implement both RTD reads, the needle logic, battery ADC, and every setting you listed — all persisted in NVS → Full handover: commented code, build instructions, and a README that gets you compiling in Arduino IDE first try I'll respond fast when you send over the Squareline files. Let's get this flashed and running.

@shahzaib81829

I can integrate your finished SquareLine UI with the ESP32-CYD and deliver clean Arduino IDE firmware that reads both RTD probes, controls the gauge needle, displays battery percentage, implements all settings with NVS persistence, and includes complete build instructions plus a concise README. I have experience with ESP32, LVGL, ADC sensing, and embedded UI integration, and can work closely with you to complete the project efficiently.

@soniaer987

Your Squareline screens look great, and I love that all the IDs and events are set — that's the hard part done. I can take it from here and get the firmware wired up so those screens actually do their thing. Here's what I bring to this: → I've worked with ESP32 and Squareline/LVGL before, so importing your project and mapping the events will go smoothly → I'll handle the RTD reads, needle angle, battery ADC, and all your NVS settings — the full feature list → I'll write clean, commented code plus a README that gets you flashing in Arduino IDE without hunting for missing libraries I can deliver this for 40, and I'll be quick to ask smart questions so we nail it in one pass. Let's get started! I'm ready to dig into your files whenever you are.

@melopgabriel

Hi I can bring your finished SquareLine UI to life on the ESP32-CYD exactly as designed. The main screen logic is clear: read both RTD probes, compare them each cycle, move the needle to the hotter probe, and keep the battery indicator updated from the ADC. I’ve built ESP32 + LVGL firmware before, including SquareLine imports, touch/UI event wiring, sensor polling, NVS persistence, and display settings like brightness, themes, units, and sleep timers. I’ll keep the code clean and commented so it’s easy to maintain. My approach is to wire the generated UI into a stable Arduino sketch, separate sensor and settings logic into tidy files, persist every option in NVS, and provide a short README with exact Arduino IDE build steps and required libraries. If you’re ready, I can start by mapping the exported assets and events into the firmware. Best regards, Gabriel

@mojjammil

I've worked on a few LVGL/ESP32 projects where the Squareline-generated UI and the sensor reading loop fight for cycle time—keeping the gauge smooth while polling ADC and RTDs without blocking the display is usually the main balancing act. I'd start by importing the Squareline project and verifying the display driver works with your CYD board, then wire the RTD readings and ADC battery measurement into separate update functions that run on a schedule independent of the UI refresh. The settings would go into NVS with a simple load/save wrapper. The main risk is gauge jitter if the RTD readings fluctuate—I'd add a simple moving average or hysteresis to keep the needle stable. Two things that would help me scope this: - Which RTD sensors are you using (PT100, PT1000) and what's the communication interface—I2C, SPI, or analog? - For the gauge needle, does the Squareline component expect a 0–100 value, or does it use degrees/angles directly? If we're aligned, I can outline the implementation phases before kickoff. Best regards Mojjammil

@warnerb7

Hello, In my opinion, the problem of this project is that the firmware must seamlessly integrate with the existing UI while ensuring real-time data handling and user settings persistence. I will import the Squareline project and connect it to LVGL, ensuring the architecture supports efficient data flow between UI elements and the ESP32's ADC for battery monitoring. The logic will compare RTD sensor values each cycle to drive the gauge needle accurately. User settings will be implemented with careful attention to edge cases, using NVS for persistence without impacting existing configurations. The deliverable will include a well-commented .ino sketch, a concise README, and any necessary header/source files for a straightforward compile and flash experience in Arduino IDE. I have successfully completed similar projects with ESP32 and LVGL. I’d love to discuss in more detail. Regards.

Bid amount and timeline above are rough placeholders; we'll firm those up once we've had a quick look at your Squareline project files. We can see you've already done the heavy lifting on the UI side, two screens, component IDs, event hooks, all wired up in Squareline Studio for the ESP32-CYD. What's left is the firmware layer that actually makes those elements respond to real hardware. That means reading two RTD probes each cycle, picking the higher reading to drive the needle angle, pulling battery voltage off the ADC, and wiring every settings control through to NVS so nothing resets on power cycle. Clean, well-commented .ino that compiles first try in Arduino IDE, no dependency hunting. Here's how we'd approach this: - LVGL integration: import your Squareline export, bind the generated ui.h to the ESP32-CYD display driver, confirm every screen and component renders correctly before touching any sensor code. - RTD reading and needle logic: read both probes each loop cycle using the appropriate SPI or MAX31865 library, compare values, map the higher reading to the gauge needle angle via lv_img_set_angle or lv_arc_set_value depending on your component type. - Battery ADC: sample the ESP32's ADC pin, apply the right voltage divider scaling, and push the result to the battery label/bar element already in your UI. - Settings persistence: each settings control (brightness, theme, unit toggle, sensitivity, sleep timeout) writes to NVS on change and reads back on boot, so user prefs survive a reset. - Build and handover: clean Arduino IDE project with all dependencies listed, a short README covering flash steps, and any extra .h files needed so you can build and flash in one go. After a short scope chat we'll put together a written proposal covering deliverables, timeline and a firm price. Want to jump on a quick call or just drop your Squareline export here so we can take a look before quoting firm numbers? Best, 96 Studio

@vertechsolutions

Hello, I will turn your Squareline two-screen UI into a working Arduino sketch that wires component IDs to LVGL, reads both RTD probes, drives the gauge needle to the higher temperature, and reports battery % from the ESP32 ADC. I have spent the last 4 years solving exactly this type of problem. I'll import your Squareline project, map component IDs to LVGL objects, implement RTD reads with filtering, compute and animate needle angles, implement settings (sensitivity, theme, info panel, brightness, units, sleep timeout) persisted to NVS, and deliver a clean, well-commented .ino, modular headers, and build/flash steps. My Embedded Systems experience and Software Engineering practices with Arduino libraries ensure reliable, maintainable firmware. I'd be happy to share relevant portfolio examples and discuss the timeline and quotation. Thanks, syed ribal www.freelancer.com/u/vertechsolutions

@anderslh

I fully understand your goal of creating a production-ready firmware for your nervoscope where both screens function exactly according to your completed interface design. Your approach is excellent because having the UI and component events prepared significantly reduces development time and improves reliability. I can implement the firmware layer, integrate all hardware features, and provide a complete handover package with source files and flashing instructions. Do you already have the ESP32 pin mapping and hardware wiring documentation available?

@andersh45

I understand that you have already completed the Squareline interface and need someone to handle the Arduino firmware development that connects everything together. I really like your workflow because designing the UI first creates a clear user experience before moving into embedded development. My team can help you finish this efficiently by implementing the screens, settings, sensors, battery monitoring, and storage features exactly as required. Can you provide the current Squareline export files and any existing Arduino code you have?
