Crate nesso 

Public Rust facade crate for the Arduino Nesso N1.

nesso is the crate applications should normally depend on. It owns the Nesso N1 board bring-up path and exposes lower-level hardware modules for advanced use.

Short facade calls borrow the shared I2C bus only for the duration of one operation, which keeps async applications cooperative without making the base crate depend on Embassy.

Example

#![no_std]
#![no_main]

use embedded_graphics::{pixelcolor::Rgb565, prelude::RgbColor};
use embedded_hal::delay::DelayNs;
use esp_hal::{clock::CpuClock, delay::Delay, main};
use nesso::Nesso;

#[main]
fn main() -> ! {
    let config = esp_hal::Config::default().with_cpu_clock(CpuClock::max());
    let peripherals = esp_hal::init(config);
    let mut delay = Delay::new();
    let mut nesso = match Nesso::new(peripherals) {
        Ok(nesso) => nesso,
        Err(_) => esp_hal::system::software_reset(),
    };

    if nesso.display.clear(Rgb565::BLACK).is_err()
        || nesso
            .display
            .print_centered("Hello from nesso", 120, Rgb565::WHITE)
            .is_err()
    {
        esp_hal::system::software_reset()
    }

    loop {
        delay.delay_ms(1000);
    }
}
