μITRON × Rust

itron

A Rust interface to interact with operating systems based on μITRON or its derivative.

This is not an officially supported project.

Examples

Cargo.toml:

[dependencies]
itron = { version = "0.1.0", features = ["asp3", "dcre"] }

Using the low-level binding:

use core::{mem, ptr};
use itron::abi::{acre_tsk, TA_ACT, T_CTSK, EXINF, ID};

fn create_task(param: isize) -> ID {
    extern "C" fn task_body(exinf: EXINF) {
        let _param = unsafe { exinf.assume_init() };
    }

    let er = unsafe {
        acre_tsk(&T_CTSK {
            tskatr: TA_ACT,
            exinf: mem::MaybeUninit::new(param),
            task: Some(task_body),
            itskpri: 4,
            stksz: 2048,
            stk: ptr::null_mut(),
        })
    };

    assert!(er >= 0, "could not create a task (error {})", er);
    er
}

Using the safe, high-level binding (experimental, requires unstable feature):

use itron::task;

fn create_task(param: isize) -> task::Task {
    let task_body = move || {
        let _param = param;
    };

    let new_task = task::Task::build()
        .start(create_task)
        .stack_size(2048)
        .initial_priority(4)
        .finish()
        .expect("could not create a task");

    new_task.as_ref().activate().unwrap();

    new_task
}

TOPPERS TGKI: Remove `USE_64BIT_HRTCNT` assumption

This crate currently unconditionally assumes defined(USE_64BIT_HRTCNT) even though not every target-specific kernel port enables it.
