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>

//! # Target support
|
|
//!
|
|
//! This module / API is only available on these compilation targets:
|
|
//!
|
|
//! - ARM architectures which instruction set include the LDREX, CLREX and STREX instructions, e.g.
|
|
//! `thumbv7m-none-eabi` but not `thumbv6m-none-eabi`
|
|
//! - 32-bit x86, e.g. `i686-unknown-linux-gnu`
|
|
//!
|
|
//! # Benchmarks
|
|
//!
|
|
//! - compilation settings
|
|
//! - `codegen-units = 1`
|
|
//! - `lto = 'fat'`
|
|
//! - `opt-level = 'z'`
|
|
//! - compilation target: `thumbv7em-none-eabihf`
|
|
//! - CPU: ARM Cortex-M4F
|
|
//!
|
|
//! - test program:
|
|
//!
|
|
//! ``` no_run
|
|
//! use heapless::box_pool;
|
|
//!
|
|
//! box_pool!(P: ()); // or `arc_pool!` or `object_pool!`
|
|
//!
|
|
//! bkpt();
|
|
//! let res = P.alloc(());
|
|
//! bkpt();
|
|
//!
|
|
//! if let Ok(boxed) = res {
|
|
//! bkpt();
|
|
//! drop(boxed);
|
|
//! bkpt();
|
|
//! }
|
|
//! # fn bkpt() {}
|
|
//! ```
|
|
//!
|
|
//! - measurement method: the cycle counter (CYCCNT) register was sampled each time a breakpoint
|
|
//! (`bkpt`) was hit. the difference between the "after" and the "before" value of CYCCNT yields the
|
|
//! execution time in clock cycles.
|
|
//!
|
|
//! | API | clock cycles |

//! | `pool::boxed::Box::drop` | 23 |

|
//! | `ObjectPool::request` | 23 |
|
|
//! | `pool::object::Object::drop` | 23 |
|
|
//!
|
|
//! Note that the execution time won't include `T`'s initialization nor `T`'s destructor which will
|
|
//! be present in the general case for `Box` and `Arc`.
