Motor-controller configuration in the browser

The problem

Configuring a motor controller meant working through its parameter description files, running separate flashing and serial tools, and setting values by hand: work for specialists. Each new motor application started from hand-set parameters and trial on the bench.

What we built

We built a web application that talks to the controller straight from the browser, over the controller's own serial bus. It reads the controller's parameter description files and shows the parameters in a basic view for everyday users and an expert view for engineers. Live charts stream speed, current, voltage and temperature, configurations are saved and versioned per project, and a guided flow takes a user from connection through a motor template and firmware to automatic tuning.

What production made hard

• Browsers reach hardware through a narrow serial interface, so connecting, retrying and timing out had to survive cables, drivers and power cycles.
• Parameter files are written for tools, not people; deciding what an everyday user sees was product work as much as parsing.
• Automatic tuning moves a real motor, so every step needed limits and a safe way to stop.

What a similar project needs

• Bench hardware and the controller's documentation available to the team from the first week.
• A clear line between what everyday users may change and what stays behind an expert view.
• Field users willing to try a beta and say what confuses them.
