Make sure the description contains information about the firmware version you're using, your platform, and a clear explanation of the 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](https://github.com/flipperdevices/flipper-application-catalog). If you are unsure, reach out to us on the [Discord Server](https://flipp.dev/discord) or the [Issues](https://github.com/flipperdevices/flipperzero-firmware/issues) page, and we'll help you find the right place for your code. Also, please read our [Contribution Guide](/CONTRIBUTING.md) and our [Coding Style](/CODING_STYLE.md), and make sure your code is compatible with our [Project License](/LICENSE). Finally, open a [Pull Request](https://github.com/flipperdevices/flipperzero-firmware/pulls) and make sure that CI/CD statuses are all green. # Development 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. C, C++, and armv7m assembly languages are supported for Flipper applications. # Firmware RoadMap [Firmware RoadMap Miro Board](https://miro.com/app/board/uXjVO_3D6xU=/) ## 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): - [Flipper Zero Wi-Fi Development Board](https://shop.flipperzero.one/products/wifi-devboard) - ST-Link - J-Link Flipper Build System will take care of all the other dependencies. ## Cloning source code Make sure you have enough space and clone the source code: ```shell git clone --recursive https://github.com/flipperdevices/flipperzero-firmware.git ``` ## Building Build firmware using Flipper Build Tool: ```shell ./fbt ``` ## Flashing firmware using an in-circuit debugger Connect your in-circuit debugger to your Flipper and flash firmware using Flipper Build Tool: ```shell ./fbt flash ``` ## Flashing firmware using USB Make sure your Flipper is on, and your firmware is functioning. Connect your Flipper with a USB cable and flash firmware using Flipper Build Tool: ```shell ./fbt flash_usb ``` ## Documentation - [Flipper Build Tool](/documentation/fbt.md) - building, flashing, and debugging Flipper software - [Applications](/documentation/AppsOnSDCard.md), [Application Manifest](/documentation/AppManifests.md) - developing, building, deploying, and debugging Flipper applications - [Hardware combos and Un-bricking](/documentation/KeyCombo.md) - recovering your Flipper from the most nasty situations - [Flipper File Formats](/documentation/file_formats) - everything about how Flipper stores your data and how you can work with it - [Universal Remotes](/documentation/UniversalRemotes.md) - contributing your infrared remote to the universal remote database - And much more in the [documentation](/documentation) folder # Project structure - `applications` - applications and services used in firmware - `assets` - assets used by applications and services - `furi` - Furi Core: OS-level primitives and helpers - `documentation` - documentation generation system configs and input files - `firmware` - firmware source code - `lib` - our and 3rd party libraries, drivers, etc. - `scripts` - supplementary scripts and python libraries home Also, see `ReadMe.md` files inside those directories for further details. # Links - Discord: [flipp.dev/discord](https://flipp.dev/discord) - Website: [flipperzero.one](https://flipperzero.one) - Forum: [forum.flipperzero.one](https://forum.flipperzero.one/) - Kickstarter: [kickstarter.com](https://www.kickstarter.com/projects/flipper-devices/flipper-zero-tamagochi-for-hackers)
