esp-cpp/uart_serial_plotter

Python application using PyQt5 and PyQtGraph for fast real-time plotting and analysis of CSV-formatted logs coming over the serial port.

uart_serial_plotter

This project provides pyqtgraph based applications for real-time plotting and analysis of timeseries data

Features

• Fast, real-time plotting of time series data
• Plot timeseries data received over UART
• Plot timeseries data read from CSV file
• Dynamically change the serial port being monitored
• Detect new USB devices connected to system and automatically update available serial ports
  • Currently only implemented for Windows
• Export the plot / scane to PNG, SVG, CSV etc.
• Load previously exported CSV files of plot / scene
• Zoom into parts of the plot, reset the view, export/screenshot select portions of the plot
• Reset the connected device using DTR/RTS hardware flow control
  • Tested on ESP32

Notes:

• For M1 Macs, you can either run the MacOS release or, if you are developing / would like to run source, you may need to follow the instructions here to use a python environment within rosetta: https://stackoverflow.com/questions/65901162/how-can-i-run-pyqt5-on-my-mac-with-m1chip
