Rust for Flipper Zero 🐬❤️🦀

This project allows writing Rust-based applications for the Flipper Zero.

It doesn't have any direct dependency on flipperzero-firmware or toolchain, so it can be used to build binaries with no external dependencies.

These crates only support the core and alloc crates.

The Rust thumbv7em-none-eabihf target currently only supports no_std development. This means it's not possible to use anything in the std crate.

SDK version

Currently supports SDK 11.2 ([email protected]).

The Rust crate version number will be updated after a major API version bump in the Flipper Zero firmware.

Crate version	API version
0.6.x	11.2
0.5.x	10.1
0.4.x	7.5
0.3.x	2.2

Crates

• flipperzero: High-level safe bindings
• flipperzero-alloc: Custom global allocator (required for alloc)
• flipperzero-rt: Runtime support (including panic handler and entry point helper)
• flipperzero-sys: Low-level bindings to Flipper Zero API (unsafe)

Initial setup

1. Install rustup by following the instructions on rustup.rs.
2. Use rustup to install the thumbv7em-none-eabihf target:

   rustup target add thumbv7em-none-eabihf
   

Writing an external app

The Flipper Zero supports installing externally built applications on the SD card.

See examples/hello-rust for an example application.
