Crate stcc4 

STCC4 CO2 sensor driver (no-std).

This crate provides a platform agnostic driver for the Sensirion STCC4 CO2 sensor. It supports both blocking and async modes via embedded-hal and embedded-hal-async.

Features

• async (default): Enables async support via embedded-hal-async.
• defmt: Enables defmt::Format derives and adds defmt logging statements.
• serde: Enables serde support for public data types (no std features).

Usage (blocking)

use stcc4::blocking::Stcc4;

let mut stcc4 = Stcc4::new(delay, i2c);
stcc4.start_continuous_measurement().ok();
let measurement = stcc4.read_measurement().ok();
stcc4.stop_continuous_measurement().ok();

Usage (async)

use stcc4::asynchronous::Stcc4;

let mut stcc4 = Stcc4::new(delay, i2c);
stcc4.start_continuous_measurement().await.ok();
let measurement = stcc4.read_measurement().await.ok();
stcc4.stop_continuous_measurement().await.ok();
