#SerialPlot

Small and simple software for plotting data from serial port in realtime.

SerialPlot v0.4 Screenshot

#Features

  • Reading data from serial port
  • Binary data formats (u)int8, (u)int16, (u)int32, float
  • User defined frame format for robust operation
  • ASCII input (Comma Separated Values)
  • Synchronized multi channel plotting
  • Define and send commands to the device in ASCII or binary format
  • Take snapshots of the current waveform and save to CSV file

See hackaday.io page for screenshots.

#Installation

You can obtain windows and linux binary packages hackaday.io page:

https://hackaday.io/project/5334-serialplot-realtime-plotting-software

#Dependencies

  • Qt 5, including SerialPort module
  • Qwt 6.1

#Building

#Obtain Dependencies

  • Qt5 development packages
  • Qt5 SerialPort module
  • CMake
  • Mercurial

Under Ubuntu/Debian: apt install qtbase5-dev libqt5serialport5-dev cmake mercurial

#Download and Install Qwt [Optional]

Qwt is the library that provides plotting widgets for SerialPlot. You have 3 different options for Qwt.

  • Leave it to serialplot build scripts. Qwt will be downloaded and built for you.

  • If your linux distribution has libqwt-qt5-dev or qwt-qt5-devel package, install it and set BUILD_QWT cmake option to false.

  • Download Qwt 6 here and build it yourself per these instructions and install. Make sure you use Qt5 (not Qt4) to build. And set BUILD_QWT cmake option to false.

#Download and Build SerialPlot

You can use Mercurial to download SerialPlot source code. Or you can download it from here: https://hg.sr.ht/~hyozd/serialplot/

hg clone https://hg.sr.ht/~hyozd/serialplot/
cd serialplot
mkdir build && cd build
cmake ..
make

You can also build with QtCreator IDE (or qmake) using serialplot.pro file.

#Known Issues

  • On Ubuntu 16.04 / Linux Mint 18, removing USB serial device while it is open in SerialPlot, causes application to go into a nasty loop and eventually it crashes. This is a bug of Qt 5.5. I have uploaded a patched version of the problematic libqt5serialport5 package to launchpad ppa. If you install SerialPlot from there or use AppImage binary, you shouldn't have any problems.
