Embedded Camsense-X1

Platform agnostic Rust driver for the Camsense-X1 LiDAR sensor, based on the embedded-hal traits.

This library provides a no_std interface for interacting with the Camsense-X1 LiDAR sensor.

Most of the information about the inner workings of the LiDAR was taken from:

Features

no_std & zero-allocations: Fully compatible with bare-metal and RTOS targets. Uses fixed-size arrays and avoids heap allocation.
Platform-Agnostic I/O: Built on embedded-hal, embedded-io traits for blocking, embedded-hal-async and embedded-io-async for asynchronous communication, supporting any UART peripheral and delay backend.
Blocking and Asynchronous Interfaces: Provides interfaces for both blocking and asynchronous (async feature) communication.
Robust Protocol Synchronization: Const-generic state machine for byte-level frame detection with automatic recovery from noisy UART lines.
Checksum Validation: Implements exact SDK algorithm (linear accumulator with 15-bit folding) to silently drop corrupted frames.
