Development repository for work related to an open source guitar controller adapter.
Work is primarily focused on wii guitars in the short term as a low cost, high performance alternative to the raphnet adapter.
Eventually, it will support more controller backends such as PS2 and direct GPIO, and more generic gamepads rather than guitars specifically.
Regardless of the backend, shredlink enumerates to the host PC as a standard HID gamepad so that it can be easily mapped in-game, just like the raphnet adapter. Eventually, this will support bluetooth connection as well.
This firmware should remain hardware agnostic in the application layer, such that it can easily be adapted to any host processor, possibly even eventually supporting reflashing of off the shelf adapters.
Shred Link is based on the Zephyr RTOS, so before getting started, make sure to have a proper Zephyr development environment. You can follow the official Zephyr Getting Started Guide.
The first step is to initialize the workspace folder where this repository and all Zephyr modules will be cloned. You can do that by running:
# initialize workspace (main branch)
west init -m https://github.com/bpbradley/shredlink --mr main shredlink-workspace
# update Zephyr modules
cd shredlink-workspace
west updateThe application can be built by running:
west build -b $BOARD -s appwhere $BOARD is the target board, nrf52840dk_nrf52840 for example
A sample debug configuration is also provided. You can apply it by running:
west build -b $BOARD -s app -- -DOVERLAY_CONFIG=`configs/debug.conf`Once you have built the application you can flash it by running:
west flash
