flipper-platform

Safe Rust wrappers over the Flipper Zero firmware, built on the flipperzero crate, with borrowed callbacks instead of boxed 'static ones.

• Borrowed callbacks. View port and timer callbacks are plain closures borrowed for the wrapper's lifetime: no boxing, no 'static. A view port only exists inside ViewPort::scoped, so its callbacks are always detached before anything they capture goes away.
• RAII everywhere. Every wrapper releases what it acquired on drop.
• No unsafe at the call site.

Modules

Module	What it wraps
view_port	A fullscreen view port with draw and input callbacks
canvas	Text, lines and XBM bitmaps on the canvas a draw call gets
input	Key events as exhaustively matchable enums
timer	Periodic Furi timers
backlight	Holding the backlight on, with adjustable brightness
battery	Battery charge level and charging state

Example

use flipper_platform::backlight::Backlight;
use flipper_platform::canvas::{Canvas, Font};
use flipper_platform::input::InputEvent;
use flipper_platform::view_port::ViewPort;

let mut backlight = Backlight::default();
backlight.hold();

let on_draw = |canvas: &mut Canvas<'_>| {
    canvas.clear();
    canvas.set_font(Font::Bold);
    canvas.draw_str(2, 12, c"Hello, Flipper");
};
let on_input = |_event: InputEvent| {};

ViewPort::scoped(&on_draw, &on_input, |view_port| {
    // The app's event loop goes here.
    view_port.request_redraw();
});

The view port is removed from the GUI when scoped returns, and dropping backlight hands the backlight back to the firmware.

Status

Early: the API covers what its first application needed and grows from there.
