skydroid-fpv

A no_std, allocation-free Rust implementation of the Skydroid camera FPV control protocol (reverse-engineered from the Android app, see PROTOCOL.md).

The crate builds packets to send ([packet], [command]) and parses frames you receive ([framing]), with no heap allocation: all output is written into caller-provided buffers. It works on bare-metal embedded targets and normal OS projects alike.

Features

• default = [] — pure no_std, no alloc, no std.
• std — enables the optional OS socket transport ([transport]).
• transport — implies std; enables the [transport] module.

Quick start (send a command)

use skydroid_protocol::packet::build_command;
use skydroid_protocol::command::Capture;

let mut out = [0u8; 32];
let n = build_command(&Capture::TakePicture, &mut out).unwrap();
let wire = &out[..n]; // bytes ready for the socket
assert_eq!(&wire[..12], b"#TPUD2wCAP01");
