Cntrlr - Simple, asynchronous embedded
Cntrlr is an all-in-one embedded platform for writing simple asynchronous applications on top of common hobbyist development boards.
Examples
Hello World to a serial port
#![no_std]
#![no_main]
use cntrlr::prelude::*;
use core::future::pending;
#[entry]
async fn main() -> ! {
serial_1().enable(9600).unwrap();
writeln!(serial_1(), \"Hello, World\").await.unwrap();
// Hang forever once we've sent our message
pending().await
}
Blinking LED
#![no_std]
#![no_main]
use cntrlr::prelude::*;
#[entry]
async fn main() -> ! {
pin_mode(13, PinMode::Output);
loop {
digital_write(13, true);
sleep(500).await;
digital_wrrite(13, false);
sleep(500).await;
}
}
lib.rs
:
A library for simple asynchronous embedded programming
use cntrlr::prelude::*;
use core::futures::pending;
#[entry]
async fn main() -> ! {
serial_1().enable(9600);
writeln!(serial_1(), "Hello, World").await.expect("Failed to message");
pending().await
}
For an API overview, check the prelude
module. This is the
core set of functionality provided by Cntrlr, and provides
functionality for most applications.
For hardware-specific functionality, each supported board and
microcontroller has its own module under [hw
]. Note that there
are currently both safety and ergonomics issues with these
lower-level APIs, and they don't provide much more functionality
than what is needed to implement the main Cntrlr API. They will be
expanded as time goes on, and will be improved for correcntess and
usability.
