Write Frothy, run complete forms on a connected board, and inspect its live words from the browser.

1. Plug in a Frothy-flashed ESP32 over USB.
2. Choose Connect and select the board.
3. Run File runs the open file, splicing in its include directives; running main.fr starts from a clean board. Run Line runs the line at the cursor, or the whole block from its opening or closing line.
4. Edits and the project title save automatically.

Board stuck in a saved loop? Connect and choose Interrupt and connect when offered, or hold the board's BOOT button right after pressing EN to skip saved code.

Web Serial requires a desktop Chrome, Edge, or Opera browser.
