LeanHRPT Decode

A high quality, easy to use HRPT decoder.

Usage

See the wiki.

Installation

Compiled builds for Linux and Windows are available from the releases page.

Building from source

For those who wish to compile from source you will need qtbase5-dev (at least 5.14), libcorrect, muparser and libpredict installed. After that you can compile with:

mkdir build && cd build
cmake ..
make

You may also wish to symlink the configuration files into the build directory:

# Assuming you are in LeanHRPT-Decode/build
ln -s ../presets.ini ..
ln -s ../calibration.ini ..
ln -s ../projection.ini ..

And then run the resulting binary.
