Installation

Linux

You can install SerialPlot for Ubuntu/Linux Mint (and other ubuntu based
distributions) via
Ubuntu PPA. Use
below commands to add ppa to your system and install SerialPlot.

sudo add-apt-repository ppa:hyozd/serialplot
apt update
apt install serialplot

Windows

You can obtain windows installation packages from
downloads section.

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 over
  SVN and built for you. You should have svn installed for this.

• 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://bitbucket.org/hyOzd/serialplot/downloads

hg clone https://hyOzd@bitbucket.org/hyOzd/serialplot
cd serialplot
mkdir build && cd build
cmake ..
make

You can also build with QtCreator IDE 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, you shouldn't
  have any problems.

• Port error 13 happens when closing. This is a Qt issue. It's known
  to not happen with Qt 5.4.1 . Not fatal.
