AVR Assembly Compatibility #28

RobertDaleSmith commented 3 years ago

I have an existing project written in 100% AVR assembly that I would like to extend it to include a basic USB hid joypad device. Is it possible and if so are there examples for implementing V-USB in a non C application?

I would go the other way and call your assembly code from C. Gcc even supports inline assembly but can generate the assembly from C code as well. It will be some work, though, either way seeing there are no direct examples and this repo is mostly abandoned.

Cool, I will probably go the route of calling my assembly code from C.

This repo is mostly abandoned? Is there a more active alternative?

If you find a well-maintained fork that actively develops it further, tell me.
