Usage

use yd_driver::{Lidar, TMiniPlus};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Auto-detect USB port
    let mut lidar = Lidar::<TMiniPlus>::new()?;
    
    // Get device info
    let (model, firmware, hardware) = lidar.get_device_info()?;
    println!("Model: {}, FW: {:#x}, HW: {}", model, firmware, hardware);
    
    // Start scanning
    lidar.start_scan()?;
    
    loop {
        let points = lidar.get_scan_points()?;
        for point in points {
            println!("{}°: {}mm (Q:{})", point.angle, point.distance, point.quality);
        }
    }
}

No-std Usage

use yd_driver::{Lidar, TMiniPlus};

let mut lidar = Lidar::<TMiniPlus, UART>::new(uart);
lidar.start_scan()?;

loop {
    lidar.read_scan_data()?;
    let points = lidar.get_scan_points()?;
    // Process points...
}
