OpenHantek6022

Stability: Active GitHub release (latest by date) GitHub Release Date GitHub commits since latest release

GitHub CI

OpenHantek6022 is a free software for Hantek DSO6022 USB digital signal oscilloscopes that is actively developed on github.com/OpenHantek/OpenHantek6022 - but only for Hantek 6022BE/BL and compatible scopes (Voltcraft, Darkwire, Protek, Acetech, etc.).

This project gives no support for its currently unmaintained predecessor openhantek.

  • Chinese, French, German, Polish, Russian and Spanish localisation complete, Italian and Portuguese translation ongoing - volunteers welcome!

AC coupling

A little HW modification adds AC coupling. OpenHantek6022 supports this feature since v2.17-rc5 / FW0204.

Continuous Integration

Every commit triggers a workflow on GitHub Actions that builds and packages OpenHantek6022 for:

  • Linux (*.deb, *.rpm, *.tar.gz)
  • macOS (*.dmg, *.tar.gz)
  • Windows (*.zip)

GitHub CI This status badge here (and on top) show the build status.

Building OpenHantek6022 from source

The preferred way to run OpenHantek6022 is to build it from source on your system, especially under Linux.

The easiest way to get an up-to-date working code base is to clone the code from here via

git clone https://github.com/OpenHantek/OpenHantek6022.git

and then build it locally, for this you will need the following software:

  • CMake 3.5+
  • Qt 5.4+
  • FFTW 3+ (prebuild files will be downloaded on windows)
  • libusb-1.0, version >= 1.0.16 (prebuild files will be used on windows)
  • A compiler that supports C++11 - tested with gcc, clang and msvc

We have build instructions available for Linux, Raspberry Pi, FreeBSD, Apple macOS and Microsoft Windows.

To make building for Linux even easier, I provide two shell scripts:

  • LinuxSetup_AsRoot, which installs all build requirements. You only need to call this script once (as root) if you have cloned the project.
  • LinuxBuild configures the build, builds the binary and finally creates the packages (deb, rpm and tgz) that can be installed as described in the next paragraph. If you make small changes to the local source code, it is sufficient to call make -j4 or fakeroot make -j4 package in the build directory.

Install prebuilt binary packages

  • Download Linux (built on Ubuntu 1804 LTS), Raspberry Pi (Debian stable), FreeBSD (12.1), macOS (Catalina 10.15) and Windows (Visual Studio 2019) packages for your convenience from the Releases page.
  • If you want to follow ongoing development, packages built from a fairly recent commit are available in the unstable release.
  • For RPi4 see also issue #28.
  • These binary packages are built on stable operating system versions and require an up-to-date system.
  • As I develop on a Debian stable system my preferred (native) package format is *.deb. The program itself and the *.deb package built on my local system is tested for completeness and correctness. The precompiled packages are only randomly tested - if at all - and the installation of the *.rpm packages is untested.
  • To install the downloaded *.deb package, open a terminal window, go to the package directory and enter the command (as root) apt install ./openhantek_..._amd64.deb. This command will automatically install all dependencies of the program as well.
  • For installation of *.rpm packages follow similar rules, e.g. dnf install ./openhantek-...-1.x86_64.rpm.
  • The *.tar.gz achives contain the same files as the *.deb and *.rpm packages for quick testing - do not use for a permanent installation. Do not report any issues about the *.tar.gz!
  • Get macOS packages from macports - thx ra1nb0w.
  • Get Fedora rpm packages - thx Vascom.
  • Download (untested) builds from last commit(s). Select the preferred workflow run and go to Artifacts.

Run OpenHantek6022

On a Linux system start the program via the menu entry OpenHantek (Digital Storage Oscilloscope) or from a terminal window as OpenHantek.

You can explore the look and feel of OpenHantek6022 without the need for real scope hardware by running it from the command line as: OpenHantek --demoMode.

OpenGL support

OpenHantek6022 uses the OpenGL graphics library to display the data. It requires a graphics card that supports 3D rendering and runs on legacy HW/SW that supports at least OpenGL 2.1+ or OpenGL ES 1.2+. OpenGL is selected by default, but if this does not work (i.e. the black scope window shows an error message or closes immediately after startup), you can choose the less resource-hungry OpenGL ES variant as a fallback by starting OpenHantek from the command line as follows: OpenHantek -e or OpenHantek --useGLES.

Especially on Windows, this option may be necessary to use the program.

The Raspberry Pi build uses OpenGL ES automatically, check also the graphics driver setup.

USB access

USB access for the device is required (unless using demo mode):

  • On Linux, you need to copy the file utils/udev_rules/60-openhantek.rules to /etc/udev/rules.d/ or /usr/lib/udev/rules.d/ and replug your device. If OpenHantek is installed from a *.deb or *.rpm package this file is installed automatically into /usr/lib/udev/rules.d/.

Windows USB access

  • The original Hantek driver for Windows doesn't work! You have to assign the correct WinUSB driver with one of these two solutions:
  1. Use the tool Zadig and follow the good step-by-step tutorial provided by DaPa.
  2. Install the signed WinUSB driver provided by VictorEEV.

Important!

The scope doesn't store the firmware permanently in flash or eeprom, it must be uploaded after each power-up and is kept in ram 'til power-down. If the scope was used with a different software (old openhantek, sigrok or the windows software) the scope must be unplugged and replugged one-time before using it with OpenHantek6022 to enable the automatic loading of the correct firmware. The top line of the program must display the correct firmware version (FW0209).

Specifications, features, limitations and developer documentation

I use this project mainly to explore how DSP software can improve and extend the limitations of this kind of low level hardware. It would have been easy to spend a few bucks more to buy a powerful scope - but it would be much less fun :) Please refer also to the developer info.

Contribute

We welcome any reported GitHub issue if you have a problem with this software. Send us a pull request for enhancements and fixes. Some random notes:

  • Read how to properly contribute to open source projects on GitHub.
  • Create a separate branch other than main for your changes. It is not possible to directly commit to main on this repository.
  • Write good commit messages.
  • Use the same coding style and spacing -> install clang-format and use make target: make format or execute directly: clang-format -style=file -i *.cpp *.h.
  • It is mandatory that your commits are Signed-off-by:, e.g. use git's command line option -s to append it automatically to your commit message: git commit -s -m 'This is my good commit message'
  • Open a pull request with a clear title and description.
  • Read Add a new device if you want to know how to add a device.
  • We recommend QtCreator as IDE on all platforms. It comes with CMake support, a decent compiler, and Qt out of the box.

Donate

If you really enjoy this project and would like to donate, please give it to the Free Software Foundation. Without the FSF, we wouldn't have this free software that we can use today.
