First of all, thanks! Community contributions are what makes open source great.
If your patch is minor (you’ve found a typo, you’ve added a new function, etc.), feel free to just make a forum post describing your changes.
If your changes are larger (you wrote a new library, you added support for a new peripheral, etc.), we’d prefer you submit a pull request on GitHub or send us a nicely-formatted patch via email.

Before submitting a patch, please make sure it complies with the coding standard. Consistent style throughout the source tree is an important implementation objective for us, and a patch that doesn’t comply with the coding standard we’ve set forth is likely to be sent back until it follows the standard.
We would prefer if you release each new file you submit under the MIT license. See e.g. bkp.h for an example, and the coding standard for more details. Code released under the Lesser GPL may be accepted for Wirish, but will almost certainly be rejected for libmaple proper. We will not accept patches released under the GPL.
We’re not against the GPL! It just doesn’t suit our purposes for libmaple. If you’re interested in a GPLed library for ST microcontrollers, check out libopenstm32. Also note that libraries released under the GPL are fine, we just don’t want any core libmaple or Wirish code to be GPLed.
The most convenient way for you to contribute patches is to submit a pull request on GitHub. Github provides excellent code review interfaces, which will make it easy for us at LeafLabs to communicate with you (and each other) about your patch. It also makes it easy for us to merge your patch into the libmaple source tree when the time comes.
The steps to submit a pull request are as follows:
If you don’t already have one, get a GitHub account (free).
Fork libmaple, then clone your fork to the computer you code on. GitHub provides detailed instructions on forking and cloning a repository.
Push your commits to your GitHub libmaple fork (see instructions linked in Step 2 for a step-by-step walkthrough on how to do this).
Please add a signed-off-by line to your commits which certify your developer certificate of origin [1]. For example, if your name is “John Smith”, and your email address is “jsmith@example.com”, just include the following line at the bottom of your commit messages:
Signed-off-by: John Smith <jsmith@example.com>
Submit a pull request to the LeafLabs version of libmaple.
If you’re unfamiliar with Git or would prefer not to use GitHub, you can always send us a patch via email at info@leaflabs.com. We’d love it if you used the Linux kernel patch format, but please at least include the following information in your email:
