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.

Binary bundles are available for Linux, macOS and Windows.

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
• 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?)
• make side panel and plot/serial prompt be resizeable (snappy?)
• current command entered is lost when navigating through the history
• command history is currently unlimited (needs an upper limit to prevent huge memory usage)
• ...

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.

After downloading
cargo install cargo-bundle or cargo install cargo-wix
run
cargo bundle or cargo wix to create platform-executable bundles.

It can be compiled and run on all platforms.

Tested on:

• macOS 12.4 Monterey x86
• macOS 13.2.1 Ventura ARM
• Debian 12 (Testing) x86
• Windows 10 x86
• ...

On Debian 12 (Testing) the following error occurred:

Error: glib-2.0 was not found in the pkg-config search path.

solved through

sudo apt-get install libgtk-3-dev

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