Writing drivers that work consistently across microcontrollers, embedded Linux boards, and desktop operating systems is deceptively hard. Different HALs, conflicting abstractions, and platform-specific quirks often lead to duplicated code or forests of #ifdef blocks.

In this blog series, we’ll explore how to design and implement a multi-platform Rust driver that avoids all of that — one codebase, many targets. We’ll look at how Rust’s trait system, strong type guarantees, built-in testing support, and CI-friendly workflow make this not only possible, but pleasant.
