## Adding Board Support
|
|
|
|
DongLoRa is designed to make adding new boards easy:
|
|
|
|
1. Create `src/board/your_board.rs` implementing the `init()` function
|
|
2. Add a Cargo feature in `Cargo.toml` with the board's dependencies
|
|
3. Add the board's feature/target/chip to the `Justfile` boards list
|
|
4. `build.rs` auto-discovers the new file and generates the module selector
|
|
|
|
See existing board files (`heltec_v3.rs`, `rak_wisblock_4631.rs`) as templates.
|
|
Each board file owns all hardware init and returns peripheral bundles that the
|
|
common tasks consume. No shared board code — each board is self-contained.
|
|
|
|
## Code Style
|
|
|
|
- **Clippy-clean.** `just clippy <board>` must pass with no warnings.
|
|
- **No panics in tasks.** Use `match`/`if let`/`warn!` — never `.unwrap()` in async task code. Board init (runs once at startup) may use `.expect("reason")`.
|
|
- **Display rendering uses `.ok()`.** Drawing is best-effort; display errors are not recoverable.
|
|
- **Every `let _ =` gets an inline comment** explaining why the result is discarded.
|
|
|
|
## Building and Testing
|
|
|
|
```sh
|
|
just check-all # Compile-check all boards (skips unavailable toolchains)
|
|
just build-all # Build release firmware for all boards
|
|
just clippy <board> # Lint a specific board
|
|
```
|
|
|
|
Xtensa boards (Heltec V3/V4) require the ESP toolchain via `espup`.
|
|
ARM boards (RAK 4631) build with stock `rustup`.
