Frequently Asked Questions

Can I use snippets from this site in my FRC team project?

Yes! All snippets are provided under the same license as their upstream source. For WPILib-derived snippets (most of them), you can freely use the code in your FRC project as long as you include proper attribution. See "How to Properly Attribute" above.

Do I need to include the full WPILib license?

BSD-3-Clause requires that you include the copyright notice and the full license text with your distribution. If you're shipping source code, include the LICENSE file. If you're just copying a snippet into your project, include a comment with the attribution.

What if I modify the code?

BSD-3-Clause allows modifications. Just be sure to document what changed and provide attribution to the original source. For example: "Adapted from WPILib's [example name]".

Is Snippetz404 endorsed by WPILib?

No. Snippetz404 is an independent, community-created snippet index. We are not affiliated with FIRST, WPILib, or any official FRC project. We respect their intellectual property and include proper attribution for all sourced material.
