Contributing

Our main goal is to build a healthy, sustainable community around the Flipper and be open to any new ideas and contributions. We also have some rules and taboos here, so please read this page and our Code Of Conduct carefully.

I need help

The best place to search for answers is our User Documentation. If you can't find the answer there, you can check our Discord Server or our Forum.

I want to report an issue

If you've found an issue and want to report it, please check our Issues page. Make sure that the description contains information about the firmware version you're using, your platform, and the proper steps to reproduce the issue.

I want to contribute code

Before opening a PR, please confirm that your changes must be contained in the firmware. Many ideas can easily be implemented as external applications and published in the Flipper Application Catalog (coming soon). If you are unsure, you can ask on the Discord Server or the Issues page, and we'll help you find the right place for your code.

Also, please read our Contribution Guide, and our Coding Style, and ensure that your code is compatible with our project License.

Finally, open a Pull Request and ensure that CI/CD statuses are all green.

Development

The Flipper Zero Firmware is written in C, with some bits and pieces written in C++ and armv7m assembly languages. An intermediate level of C knowledge is recommended for comfortable programming. For Flipper applications, we support C, C++, and armv7m assembly languages.

Requirements

Supported development platforms:

  • Windows 10+ with PowerShell and Git (x86_64)
  • macOS 12+ with Command Line tools (x86_64, arm64)
  • Ubuntu 20.04+ with build-essential and Git (x86_64)

Supported in-circuit debuggers (optional but highly recommended):

Everything else will be taken care of by Flipper Build System.

Cloning Source Code

Ensure that you have enough space and clone source code with Git:

git clone --recursive https://github.com/flipperdevices/flipperzero-firmware.git

Building

Build firmware using Flipper Build Tool:

./fbt

Flashing Firmware using an in-circuit debugger

Connect your in-circuit debugger to the Flipper and flash firmware using Flipper Build Tool:

./fbt flash

Flashing Firmware using USB

Ensure that your Flipper is working, connect it using a USB cable and flash firmware using Flipper Build Tool:

./fbt flash_usb
