Hey! I'm considering using your bootloader in a project, but there is no license attached, meaning it cannot be used currently. Would you care to attach a license to the code? If you're unsure what to use, I often use the MIT license which is very liberal (making the code convenient to reuse, but allows making closed-source modifications) or the commonly used GPL, which is more restrictive (requiring all derivatives and code used alongside it to be GPL as well).

Hi Matthijs,

I'm glad you're interested in using my code for your project! Do you mind if I ask what you'e making? (just curious)

I've added the GPL license to the repository. Good luck with it,

Erin

Hey Erin,

thanks for the quick reply and action!

I'm involved with the development of the 3devo Next 1.0 filament extruder (http://3devo.eu/) and we're exploring the option of using a secondary microcontroller for controlling a part of the system, which of course needs to have its firmware updateable from the main microcontroller. I compared a few bootloaders, and yours seems to be well-written and presumably easiest to adapt to an USI module instead of a TWI module.

I've added the GPL license to the repository. Good luck with it,

At the risk of nitpicking: It is generally good practice to not just include a LICENSE file, but also explicitly state the applicable license in the README and ideally at the top of all header files. Convention dictates that the license in a file called LICENSE applies to all files in the repository, but that is not really explicit. Adding a note to all source files makes the license very explicit, and makes it easier to trace the history of individual files too (when files from different authors are mixed).
