Install prebuilt binary

Navigate to the Releases page. * Download Windows build

Building OpenHantek from source

You need the following software, to build OpenHantek from source: * CMake 3.5+ * Qt 5.4+ * FFTW 3+ (prebuild files will be downloaded on windows) * libusb 1.x (prebuild files will be used on windows) * A compiler that supports C++11

We have build instructions available for Linux, Apple MacOSX and Microsoft Windows.

Run OpenHantek

You need an OpenGL 3.2+ or OpenGL ES 2.0+ capable graphics hardware for OpenHantek. OpenGL is prefered, if available. Overwrite this behaviour by starting OpenHantek from the command line like this:

OpenHantek --useGLES

USB access for the device is required: * As seen on the Microsoft Windows build instructions page, you need a special driver for Windows systems. * On Linux, you need to copy the file

and replug your device.

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 master for your changes. It is not possible to directly commit to master on this repository. - Write good commit messages. - Use the same coding style and spacing (install clang-format. Use make target:

make format
or execute directly from the openhantek directory:
clang-format -style=file src/*
). - 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.
