Last year we wrote about [Alex Spataru]’s Serial studio project, which started life as serial port data visualizer, like a souped-up version of the Arduino serial plotter. [Alex] has been actively improving the project ever since, adding a variety of new features, including

JSON editor for data formats

TCP, UDP, and Multicast

New and a lot more flexible display widgets

Multi-signal plots

FFT and logarithmic plots

VT-100 emulation

Support for plugins and themes

Added MQTT support

[Alex] originally came up with Serial studio because he was involved in ground station software for various CanSat projects, each one with similar yet slightly different data formats and display requirements. rather than make several different programs, he made a decision to make Serial studio which could be configured using JSON descriptor files.

The program is open-source and multi-platform. You can build it yourself or download pre-compiled binaries for Windows, Linux, and Mac. See the project GitHub repository for a lot more details. In addition to English, it has also been translated into Spanish, Chinese, and German. What is your go-to tool for visualizing serial data telemetry these days? let us know in the comments below.
