Implement full SSD1306 OLED display support: - Splash screen on boot (1.5s) with project name, version, board - Dashboard showing radio state, config, counters, RSSI/SNR - RSSI history sparkline (64-sample ring buffer, 2px-wide bars) - DisplayOn/DisplayOff host commands routed via dedicated channel - Pure render functions against generic DrawTarget (no hardware coupling) - Display on/off control bypasses radio task entirely Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# Migration Guide from 0.3.x to v0.4.x

|
## Initialization
|
|
|
|
You no longer have to set up clocks and pass them to `esp_hal_embassy::init`.
|
|
|
|
```diff
|
|
use esp_hal::{
|
|
- clock::ClockControl,
|
|
- peripherals::Peripherals,
|
|
prelude::*,
|
|
- system::SystemControl,
|
|
};
|
|
|
|
#[esp_hal_embassy::main]
|
|
async fn main(_spawner: Spawner) -> ! {
|
|
- let peripherals = Peripherals::take();
|
|
- let system = SystemControl::new(peripherals.SYSTEM);
|
|
- let clocks = ClockControl::boot_defaults(system.clock_control).freeze();
|
|
+ let peripherals = esp_hal::init(esp_hal::Config::default());
|
|
|
|
let timg0 = TimerGroup::new(peripherals.TIMG0);
|
|
- esp_hal_embassy::init(&clocks, timg0);
|
|
+ esp_hal_embassy::init(timg0.timer0);
|
|
|
|
// ...
|
|
}
|
|
```
|
|
|
|
You have to specify a timer instance (that may be a `TimerGroup` timer unit
|
|
or a `SystemTimer` alarm) or an array of `AnyTimer`s when calling `init`.
|
|
An example of how you can set multiple timers (for example when using
|
|
multiple executors):
|
|
|
|
```rust
|
|
use esp_hal::{
|
|
prelude::*,
|
|
timer::{
|
|
AnyTimer,
|
|
systimer::SystemTimer
|
|
}
|
|
};
|
|
|
|
#[esp_hal_embassy::main]
|
|
async fn main(_spawner: Spawner) -> ! {
|
|
let peripherals = esp_hal::init(esp_hal::Config::default());
|
|
|
|
let timg0 = TimerGroup::new(peripherals.TIMG0);
|
|
let timer0: AnyTimer = timg0.timer0.into();
|
|
let timer1: AnyTimer = timg0.timer1.into();
|
|
|
|
// You can use either a TimerGroup timer, a SystemTimer alarm,
|
|
// or you can mix and match them as well.
|
|
let systimer = SystemTimer::new(peripherals.SYSTIMER).split::<Target>();
|
|
let timer2: AnyTimer = systimer.alarm0;
|
|
|
|
esp_hal_embassy::init([timer0, timer1, timer2]);
|
|
|
|
// ...
|
|
}
|
|
```
|
|
|
|
Note that you only have to convert into `AnyTimer` if you want to use multiple timers.
