Uxn for the Raspberry Pi, on bare metal. Inspired by uxnrpi, though at this point it contains very little code from that project. Powered by Circle. Should support all of the Varvara devices except audio.
Currently very much a work in progress. If you want to compile it on your own, good luck. It's set up specifically for the GPi Case 2W (a Game Boy-style Pi case with a 640x480 LCD and a USB gamepad), and hasn't been tested on anything else yet.
Requires an aarch64 cross-compiler build of GCC and a custom build of QEMU to test; see Circle's instructions.
This project contains two subprojects under different licenses.
My C++ Uxn framework, in the uxn-cpp subdirectory, is distributed under the
MIT license. This will likely be split off into a separate repository in the
future.
The full uxnpi project (all source files outside the uxn-cpp subdirectory) is
distributed under the GPL 3.0, because Circle is also GPL.
