💅 galvani — the manual, but make it cute

okay bestie so picture this: it's Galvani, a whole program for plotting and evaluating measurement data, and honestly? she ate. ✨

✨ NAME ✨

Galvani — a program for plotting and evaluating measurement data 🫶

---

🌸 SYNOPSIS 🌸

galvani [options]

---

🦋 DESCRIPTION 🦋

So here's the vibe: Galvani reads measurement data from digital multimeters off a serial interface, and then plots that data graphically in a diagram. Simple as that, no cap.

You get two channels available, which means you can run 2 devices in parallel. twin energy. 👯‍♀️

🎀 math transformations for data evaluation

There are several mathematical transformations available for data evaluation:

• Inverse (1/x)
• Logarithm
• Conversion of a Copper/Constantan- or Nickel/Chromnickel-thermocouple voltage to temperature difference
• Conversion of a Pt100-thermistor resistance to temperature
• Conversion of timeline to volumina (for titrations)

💖 math operations for graph evaluation

And there are some mathematical operations available for evaluation of graphs:

• Differential function
• Integration of peak area in Chromatograms including tabulation
• Linear regression of data

🌈 export & printing

Diagrams can be exported into several file formats (PNG, SVG, EPS, PDF) or printed as report. periodt. 💅

⭐ simulation

Additionally, measurement data can be simulated (in combination with random variables) as:

• Linear function
• Exponential function (decay curve)
• Chromatogram
• Titration curve

👑 SETTINGS 👑

The appearance of diagrams can be controlled in several options. Data points can be shown as cross, circle, square or diamond and/or can be interpolated by lines or curves. iconic, truly.

All settings for serial communication with the device can be saved as files. For some devices, there exist already configuration files from which settings can be read. Also, setting measurement function remotely is possible if the device has this option. 👀

🧚 FILES 🧚

• $(HOME)/galvani — device specific settings are saved as files in this folder.
• $(HOME)/galvani/data — this folder contains the data files (.dat) produced by galvani and graphical data (.png, .svg, .eps) exported by the program. Alternatively other folders can be chosen for saving data files.
• $(HOME)/.galvani — in this hidden folder galvani saves the file galvani.ini holding information for autoloading and autosaving program settings and the configuration file galvani.conf in which all program settings are saved and can be read at program start.
• /tmp/galvani — folder for temporary files.

ngl the hidden folder one is lowkey the main character here. peep that dot. 🙈

and that's the whole page, bestie — written by Burkard Lutz back on January 11, 2023, straight out of the Galvani Manual, section galvani(1). slay, stay curvy, keep plotting. 🍓💜
