Installation Guide for Hayasen

1. Prerequisites

Rust Toolchain: Ensure that Rust (with Cargo) is installed. You can install it using:
```
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```
Embedded Development Setup:
- Install the target for your microcontroller (e.g., ARM Cortex-M):
```
rustup target add thumbv7em-none-eabihf
```
- Ensure you have an appropriate linker and build tools installed.
Optional: For cross-compilation, tools like probe-rs or cargo-embed can be used.

Add the following line to your project's Cargo.toml under [dependencies]:

[dependencies]
hayasen = "*"

You can add Hayasen directly via Cargo command:

cargo add hayasen

This ensures that your project is always linked to the latest version of the crate.

Plans include adding each sensor as a feature to reduce overhead. It has already been implemented for the MPU9250.

Therefore your full command is

cargo add hayasen --features mpu9250

A minimal Cargo.toml for a project using Hayasen might look like:

[package]
name = "sensor_app"
version = "0.1.0"
edition = "2021"

[dependencies]
hayasen = "*"
embedded-hal = "0.2"

Run a test build to ensure everything is set up correctly:

cargo build --target thumbv7em-none-eabihf

If successful, you're ready to start integrating Hayasen with your embedded projects.
