//! DongLoRa firmware — transparent LoRa radio over USB.
|
|
//!
|
|
//! Three async tasks communicate via static channels:
|
|
//!
|
|
//! ```text
|
|
//! host_task ──Command──► radio_task ──► SX1262
|
|
//! ◄──Response── │
|
|
//! StatusWatch
|
|
//! ▼
|
|
//! display_task (optional)
|
|
//! ```
|
|
//!
|
|
//! The host drives everything. The radio idles until commanded.
