Rewind with checkpoints
The VS Code extension supports checkpoints, which track Embedder’s file edits and let you rewind to a previous state. Click the rewind button on any message, or use the/undo or /rewind commands, to choose from three options:
- Fork conversation from here — Start a new conversation branch from this message while keeping all code changes intact.
- Rewind code to here — Revert file changes back to this point in the conversation while keeping the full conversation history.
- Fork conversation and rewind code — Start a new conversation branch and revert file changes to this point.
Serial console
Embedder can interact with your serial console directly. It can read serial output history to diagnose issues, send commands to your device, monitor for specific patterns, and help debug communication problems. The built-in serial console lets you communicate with embedded devices directly from VS Code. Open it from the bottom panel or as a full editor tab with theembedder.openSerialInEditor command.
Port selection
Embedder auto-detects available serial ports and displays metadata like manufacturer, vendor/product ID, and serial number. Ports refresh automatically when devices are plugged in or unplugged.Baud rate
Select from common baud rates manually, or let Embedder auto-detect the correct baud rate. Auto-detection shows a confidence level so you know how reliable the result is.Multi-tab interface
Open multiple serial connections simultaneously. Each tab maintains its own port selection, baud rate, connection state, output history (up to 50,000 lines), filter pattern, and timestamp settings.Output features
- Log level coloring — Errors appear in red, warnings in yellow, info in green, and debug in blue.
- Timestamps — Optional timestamp prefix for each line.
- Regex filtering — Filter output with regular expressions.
- Clear output — Clear the console while preserving the connection.
Connection types
Embedder supports two connection types:| Type | Description |
|---|---|
| UART | Standard serial port connections (USB-to-UART adapters, dev boards) |
| RTT | SEGGER Real-Time Transfer via J-Link probes |
J-Link integration
Embedder automatically detects connected J-Link probes and supports RTT for non-intrusive debugging output. Select your target device from a picker with search and filter, with suggested devices based on your project context. Supports both SWD and JTAG interfaces.Next steps
