What you need

MaD Control runs entirely in your browser. There is nothing to install and no server to set up.

Checklist

• Chrome or Edge on a desktop computer (Windows, macOS or Linux).

• Two USB serial adapters on the machine's controller, one per port:

  Port	Adapter	Where it plugs in	Used for
  Control port	A USB-serial adapter (FTDI or similar)	The controller's secondary serial, P30/P32: header J4 on the Edge carrier; on a P2-EVAL bench, adapter TX → P30, adapter RX ← P32, grounds joined	Everything day to day: live data, jogging, calibration, tests
  Programming port	A Parallax Prop Plug	The Debug/Programming header J1 (P62 / P63 / RESn / GND), or the P2-EVAL's own USB	Flashing firmware only

  Both can stay plugged in. Power up and connect explains why there are two.

• A folder on your computer for sample profiles, motion profiles and test results. The app asks for it the first time it opens.

• A known weight (ideally several, up to at least 20% of the load cell's capacity) for the load cell calibration.

Most adapters work out of the box on macOS and Linux. Windows may need the adapter's USB-serial driver.

Browser support

Browser	Supported	Notes
Google Chrome (desktop)	Yes	Recommended
Microsoft Edge (desktop)	Yes	Chromium-based
Brave / other Chromium	Usually	Web Serial must be enabled
Firefox	No	No Web Serial API
Safari	No	No Web Serial API
Mobile browsers	No	No Web Serial API

The app talks to the machine with the Web Serial API and saves results with the File System Access API. Only Chromium implements both. In any other browser the app shows an "unsupported browser" screen.

Installing as an app (optional)

Chrome and Edge offer to install MaD Control as a standalone window (an icon in the address bar, or ⋮ → Cast, save, and share → Install page as app…). Installed or not, it behaves the same. When a new version is published the status bar shows Update ready; it is applied only when you click it while disconnected, so the app never reloads during a test.

Next: Power up and connect.
