Demo

Live demos of ScalpelSpace hardware, running in the browser over a USB serial connection. Connect a board and the page asks it what it is, then loads that product's demo. Nothing is installed and no data leaves the machine.

This browser cannot talk to serial devices. The demos need the Web Serial API. Use desktop Chrome, Edge or Opera over https:// or http://localhost. Everything below still renders so you can see what the page does, only connecting to hardware is unavailable.

JavaScript is switched off. The demos run entirely in the browser, so nothing on this page works without it.

Device

Not connected

Plug a board into USB-C and connect. The page releases BOOT0, resets the board into its application, and asks it for its firmware version.

Boot control lines

A ScalpelSpace board wires DTR to BOOT0 and RTS to NRESET so it can be flashed hands free. That also means opening a port asserts BOOT0 and starts the bootloader, which answers no commands, so the page releases the lines and resets into the application on connect. Change these only for a board that maps or inverts them differently.
