⚠️ Warning: Early Development Stage

This library is currently under active development and has not been thoroughly tested. Use in production systems at your own risk. APIs may change without notice.

Hayasen is an Embedded Rust library designed to simplify sensor integration in embedded systems. It provides unified, type-safe interfaces for various sensors with a focus on ease of use and reliability.

• MPU9250 - 9-axis Inertial Measurement Unit (accelerometer, gyroscope, temperature, magnetometer) - Work in Progress
• MPU6050 - 6-axis Inertial Measurement Unit (accelerometer, gyroscope, temperature)
• MAX30102 - Pulse Oximeter, Heart Rate Monitor, Temperature Sensor

Progress

Add hayasen to your Cargo.toml:

[dependencies]
hayasen = { version = "*", features = ["mpu9250"] }   # For MPU9250 support

use hayasen::prelude::*;
use hayasen::mpu9250_hayasen;

fn main() -> Result<(), Error<YourI2cError>> {
    // Setup I2C (platform-specific)
    let i2c = setup_i2c();
    
    // Initialize sensor with default configuration
    let mut sensor = mpu9250_hayasen::create_default(i2c, 0x68)?;
    
    // Read all sensor data (temp, accel, gyro)
    let (temperature, acceleration, angular_velocity) =
        mpu9250_hayasen::read_all(&mut sensor)?;
    
    println!("Temperature: {:.2}°C", temperature);
    println!("Acceleration: [{:.3}, {:.3}, {:.3}] g",
             acceleration[0], acceleration[1], acceleration[2]);
    println!("Angular Velocity: [{:.3}, {:.3}, {:.3}] dps",
             angular_velocity[0], angular_velocity[1], angular_velocity[2]);
    
    Ok(())
}
