Licenses & Source

Open-source software included in NawiaCybernetyka products, and the corresponding source.

Our pedals run firmware built on the Teensyduino core and several Arduino libraries. Some of those components are licensed under the GNU Lesser General Public License, version 2.1, which entitles anyone who receives our firmware to the library's source and to the means of relinking it. This page provides both.

We have not modified any of these components. The source below is the unmodified upstream code we compile against, kept here so it stays available at a fixed address rather than depending on a third party's hosting.

Firmware releases

For each firmware release we distribute, we publish the application object files alongside it. Together with the library source above, these let you relink our firmware against your own modified version of any LGPL component.

No firmware has been distributed yet. Object files will appear here with the first release.

Written offer

If you received a NawiaCybernetyka product and this page is unavailable to you, write to support@nawiacybernetyka.com and we will provide the corresponding source and object files on physical media at no charge beyond the cost of the media and postage. This offer is valid for at least three years from the date you received the product.
