Serial Monitor

A cross-platform serial monitor and plotter written entirely in rust, the GUI is written using egui.
Inspired by the serial monitor/plotter from the Arduino IDE, but both plotting and reading the traffic can be done simultaneously.

Installation:

Download pre-built executables

Binary bundles are available for Linux, macOS and Windows.

Running the apple silicon binary (serial-monitor-aarch64-apple-darwin.app) may result to the message "Serial Monitor is damaged and cannot be opened.", to get around this you first need to run:
xattr -rd com.apple.quarantine Serial\ Monitor.app

On Linux first install the following:

sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev

Compile from source

The source code can be run using cargo run or bundled to a platform-executable using cargo bundle.
Currently cargo bundle only supports linux and macOS bundles see github issue. As a work-around we can use cargo wix to create a windows installer.

Ubuntu

sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev
cargo install cargo-bundle
cargo bundle

Debian

sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev libudev-dev
cargo install cargo-bundle
cargo bundle

macOS

cargo install cargo-bundle

Windows

cargo install cargo-wix
cargo wix

Features:

• Plotting and printing of data simultaneously
• Smart data parser, works with ", " or "," or ":" or ": "
• History of the past sent commands
• Low CPU Usage, lightweight
• Clear history options
• Data Window width (number of displayed datapoints in plot) is adjustable
• Cross-platform, fully written in Rust
• Ability to save text to file
• Ability to save the plot
• Allow to put in labels for the different data columns (instead of column 1, 2, ...)
• Allow to choose Data-bits, Flow-Control, Parity and Stop-Bits for Serial Connection
• Saves the configuration for the serial port after closing and reloads them automatically upon selection
• Option to save raw data to file
• Use keyboard shortcuts (ctrl-S to save data, ctrl-shift-S to save plot, ctrl-X to clear plot)
• Automatic reconnect after device has been unplugged
• Color-picker for curves
• Open a CSV file and display data in plot
• Allow to select (and copy) more than just the displayed raw traffic (also implement ctrl + A)
• Smarter data parser
• make serial print selectable and show corresponding datapoint in plot
• COM-Port names on Windows (display manufacturer, name, pid or vid of device?)
• current command entered is lost when navigating through the history
• command history is currently unlimited (needs an upper limit to prevent huge memory usage)
• data history is currently unlimited (needs an upper limit to prevent huge memory usage)
• ...

Tested on:

• macOS 12 Monterey x86
• macOS 13 Ventura x86
• macOS 13 Ventura ARM
• macOS 14 Sonoma ARM
• Debian 12 (Testing) x86
• Windows 10 x86
• ...

One might have to delete the Cargo.lock file before compiling.
