libjoycon

A Joycon packet encoding and decoding lib

Build

The library itself only links to the libm (math lib):

mkdir build && cd build
cmake ..
make

If you want to build examples, the HIDAPI lib is a must. The OpenGL and GLUT/Vulkan is necessary to build IMU Mapping. Configure the project with BUILD_EXAMPLE as follows:

cmake -DBUILD_EXAMPLE=ON ..

Python bindings

If swig is installed, bindings for python will also be built.

To use the Python examples, install hidapi(also and taichi to run the taichi example) in pip. In Linux, remember to build the hidapi manually in order to connect to Joycon through Linux hidraw API:

git clone --recursive https://github.com/trezor/cython-hidapi.git
python setup.py build --without-libusb

Usage

Please refer the programs in examples.

Note

Note that this library does not contain Bluetooth/USB HID implementation, you can use one on a specific platform, e.g. hidapi on Linux/Win, to read/send raw packets, and use this library to extract/encode information from/to the packets.
