基于 SOC 职业分类
Interfacing with Raspberry Pi Pico using picotool, serial communication, and defmt logging. Use when flashing firmware, debugging, setting up serial telemetry, or configuring defmt/probe-rs logging.
Embassy HAL for Raspberry Pi RP2040 and RP2350 microcontrollers. Use when working with Pico/Pico 2 peripherals, GPIO, SPI, I2C, UART, PIO, or flashing with picotool.
Ground station subproject context. Use when working in the ground_station package, telemetry reception, mission control interface, or real-time flight monitoring.
Interface with the Orange Pi payload computer over SSH for development and debugging. Use when connecting to the Orange Pi, running commands remotely, deploying code, checking system status, or troubleshooting the payload computer.
Guidance for embedded sensor drivers used in the payload. Use when working with BMP390, ENS160, LSM6DSOX, LIS3MDL, GPS, IMU, barometer, or any sensor integration.
Flight computer subproject context. Use when working in the flight_computer package, camera capture, video processing, audio recording, or high-level mission logic.

Embassy is a modern embedded framework using Rust's async/await for efficient, safe embedded programming.
Async task runtime for embedded systems.
#![no_std]
#![no_main]
use embassy_executor::Spawner;
#[embassy_executor::main]
async fn main(spawner: Spawner) {
spawner.spawn(background_task()).unwrap();
// Main task continues...
}
#[embassy_executor::task]
async fn background_task() {
loop {
// Do work...
Timer::after_secs(1).await;
}
}
Timers, delays, and timeouts.
use embassy_time::{Timer, Duration, Instant};
// Delay
Timer::after(Duration::from_millis(100)).await;
Timer::after_secs(1).await;
// Timeout
let result = with_timeout(Duration::from_secs(5), async_operation()).await;
// Measuring time
let start = Instant::now();
do_work().await;
let elapsed = start.elapsed();
Synchronization primitives for async contexts.
use embassy_sync::{
mutex::Mutex,
channel::Channel,
signal::Signal,
};
use embassy_sync::blocking_mutex::raw::CriticalSectionRawMutex;
// Shared state
static SHARED: Mutex<CriticalSectionRawMutex, u32> = Mutex::new(0);
// Channel for message passing
static CHANNEL: Channel<CriticalSectionRawMutex, Message, 4> = Channel::new();
// Signal for notifications
static SIGNAL: Signal<CriticalSectionRawMutex, ()> = Signal::new();
Async traits for embedded-hal compatibility.
| Crate | Purpose |
|---|---|
| embassy-net | TCP, UDP, DHCP, ICMP networking |
| embassy-usb | Device-side USB (CDC, HID, custom) |
| embassy-boot | Power-fail-safe firmware updates |
| trouble | Bluetooth Low Energy 4.x/5.x |
