Flux is an AI hardware engineer. Flux writes, builds, and tests firmware that connects a device's schematic, board, and mechanical design.
Firmware workflows
Tell Flux what the device must do and which parts it uses. Flux can write a firmware starter document from the schematic, map pins and peripherals, compile firmware, run host tests, and prepare a board bring-up plan. It can also work from your code and use values from a mechanical model in firmware constants.
Open the Chat panel in your project and describe the device behavior. Flux can use the schematic, project files, and mechanical model in the same project. Ask for one outcome at a time or describe the whole device and its firmware.
Firmware connects the electronics to the behavior of a complete product. Flux can initialize sensors and actuators, manage Wi-Fi or BLE, sequence startup, and set up error handling and a watchdog. When the board or its connections change, Flux can update the firmware document, pin map, and bring-up plan with the design.
Firmware reference pages
Tell Flux which part of the firmware workflow you want to complete next. Use the pages below to choose a focused task and the details to include.
Open Chat to ask Flux, or select Files in the project view switcher to read the firmware starter document and bring-up plan. Use these pages to guide each step:
Write firmware from the schematic or from your own source.
Set up pins and peripherals from schematic connections.
Build and test firmware, inspect output files, and prepare a flashing command.
Bring up your board with a project plan and test firmware.
Keep firmware in sync with your hardware as the device changes.
Use firmware prompt examples to make a request specific.
Firmware for the complete device
Tell Flux how firmware fits with the other parts of your product. Flux can connect the schematic and PCB with mechanical dimensions, simulation results, manufacturing needs, and project documentation.
Open the Chat panel for design work. Select Files in the project view switcher to find project documents and generated firmware files. To connect a firmware-development service, select AI Integrations in Chat, open the Integrations tab, and choose Firmware & Development.
Firmware can use a mechanical value such as sensor position or enclosure dimensions. Flux can then keep that value with the source and update it when the model changes. You can also connect public code repositories and a firmware-monitoring integration to use code and field crash data in the next revision. This keeps the firmware behavior connected to the physical location and size of the components in the device.
Use project files to keep the design work together. The firmware starter document records the board setup and source. The pin map connects code to schematic nets. The bring-up plan lists how to test the assembled board. Generated images and test results remain available beside these project documents.
Use the related pages to connect firmware to the full device workflow:
Mechanical Design covers parts, assemblies, and product geometry.
Schematic Design connects component pins and nets.
Simulation checks circuit and device behavior.
Manufacturing with Flux prepares for board and mechanical manufacturing.
Project files organize the firmware starter document, tests, and build outputs.
Integrations and secrets explains connected services.
