ComChan is a terminal-based serial monitor designed for communicating with microcontrollers, development boards and other serial-connected hardware. It provides interactive access to device output and allows commands to be transmitted directly from the terminal, making it suitable for debugging firmware, examining sensor readings and monitoring embedded applications.
In addition to conventional serial communication, ComChan provides specialised facilities for analysing data produced by connected devices. It combines text-based monitoring with graphical terminal displays, allowing numeric information to be examined as it arrives rather than requiring separate plotting software. The application also supports alternative debugging connections that do not rely exclusively on conventional UART interfaces.
Its interactive terminal interface is particularly useful when several sources of diagnostic information need to be examined together. Users can monitor two serial connections side by side, inspect previous output and move between communication and visualization workflows during a debugging session.
This is free and open source software.
Key Features
- Reads incoming serial data and transmits commands to connected devices.
- Provides a scrollable terminal interface with searchable communication history.
- Supports simultaneous monitoring of two serial ports in a split-pane interface.
- Offers independent scrolling and separate logging for dual-port sessions.
- Supports line charts, bar charts, scatter plots and histograms for serial data.
- Provides a 3D spatial telemetry display for motion and orientation data.
- Supports Bluetooth Low Energy communication using Nordic UART Service.
- Provides RTT and defmt logging through supported hardware debug probes.
- Offers hexadecimal views for examining binary communication.
- Supports continuous CSV recording and terminal session replay.
- Exports generated charts to SVG.
- Allows switching between monitoring and plotting without restarting the application.
- Supports session detachment and subsequent reconnection.
- Includes simulated data sources for testing without connected hardware.
