Basics

Rust no_std driver crate for PCA9546A 4-channel I2C multiplexer, based on embedded-hal. Evidence: Cargo.toml, src/.

Taxonomy

Tags: embedded-hal driver, I2C

Architecture

Small library crate: wraps channel selection and bus switching behavior behind embedded-hal abstractions. Evidence: src/lib.rs, Cargo.toml.
Intended to be embedded as a building block inside larger firmware repos. Evidence: Cargo.toml.

Conventions

Uses no_std and embedded categories in metadata. Evidence: Cargo.toml.
Standard repo layout with minimal surface area. Evidence: src/.

Taste notes

These “infrastructure drivers” (muxes/expanders) are best kept tiny and composable; this crate’s scope fits that philosophy.
