Hydron

About

Hi HN, this is Prashant from H2Loop. Embedded engineers that we work with were annoyed that generic AI tools hallucinated register addresses, generated code for peripherals that don't exist on the chip and mixed up timer quirks between similar platforms like STM32F4 and F7. The code looks clean but it just won't boot. This made them go back to the datasheet every time. So we built Hydron, an AI tool that writes datasheet-grounded code for your hardware.Demo: Hydron setting up sleep-mode CPU logging for an onboard temp sensor on an STM32U385 - https://boot.hydron.sh/zzzDemoFirst, we've pre-indexed 580+ platforms and peripherals. Most of what you'd use in a robotics, UAV, or IoT build: common dev platforms like STM32, ESP32, RP2040, AM6 families, plus the IMUs, GNSS modules, motor drivers, and baros that ship around them. Ask about a peripheral, the answer comes from our KG and the actual datasheet.Second, you can bring your own context and share it with your team. Hydron indexes PDFs up to 5000 pages, plus a whole host of various file types and even ZIPs of full C/C++/Python codebases up to 250MB. One engineer indexes the HW, BSPs, and datasheet pack once. Anyone else can reference it from their own Hydron agent.Third, HW-SW development happens in your editor or terminal. Agentic serial monitor is live today. GDB integration, and an AI log reader land in the next two weeks.Up next, we're focused on closing the hardware-software loop. We're building more HIL debugging capabilities, deeper target awareness, and support for additional platforms. If you work on embedded SW we'd love your feedback on where today's tools fall short and what you'd like to see next.Install: VS Code extension - https://marketplace.visualstudio.com/items?itemName=H2Loop.h...

which mcu families are covered and how do you validate register accuracy

RAG over datasheets or fine-tuned? ARM only at launch?

Milan Lind Milan Lind 5 days ago

sick launch! what model are you using for register validation

getting register addresses right makes embedded AI actually usable

Custom RAG pipeline over datasheets for register validation?

no more phantom peripherals, which chip families does this actually support?

Deven Dicki Deven Dicki 2 days ago

so the ai actually knows real peripherals exist? which chips does it support

runs locally or hits a cloud endpoint? matters for air-gapped setups
