Description:

spplot 0.0.2

spplot
This utility is a text mode implementation of what can be done in Arduino IDE
when choosing Serial Plotter option, i.e. it plots the numbers received on
the serial port in real time.

spemu
There's also a helper utility included, called spemu which is a serial port
emulator. It's useful for testing when no real device is nearby.
Usage
Run spemu. The program will print file descriptor and PTY device path.
You can write directly to the spemu stdin or open file descriptor with some
script and write to it. The things you write will be outputted by the virtual
COM port.
Installation
spplot
Install from PyPI:
python3 -m pip install spplot

Install locally:
python3 -m pip install . --upgrade

spemu
To compile it, just run make.
Requirements
spplot

Python 3 with f-strings
POSIX-compliant, color-supporting terminal
Font with Braille characters
Modules from requirements.txt

spemu

C compiler
UNIX-like system

Disclaimer: Work in Progress
This is a dirty draft of what I want it to be. I'll try to optimize it in my
free time and add some colors to differentiate the plots. As for now, it is
what it is.
The initial menu is made in TUI style but if you provide port and baudrate as
CLI args, you won't see it.
Roadmap

colored lines for different subplots
total average / current buffer average and other stats
better error handling
buffer, display and calculation optimizations
proper handling of negative values
set y axis range option
plot on n-th readout option
command line args
dynamic resizing
human menu keymapping
make a python package
make a PyPI release
