Learn EMBEDDED-RUST with Real Code Examples

Use `no_std` to reduce binary size

Minimize heap allocations, prefer stack or static memory

Optimize interrupt handlers and task execution time

Leverage inline functions and zero-cost abstractions

Profile with hardware timers if precise timing is required

Memory safety is largely enforced by Rust

Avoid unsafe blocks unless necessary and review carefully

Ensure firmware authenticity when flashing

Control access to debug interfaces

Protect communication channels (encryption, authentication)

Use semihosting or RTT for real-time logging

Monitor task timing and latency

Analyze memory footprint and stack usage

Log peripheral data for debugging

Audit firmware for safety and correctness

Use Rust idiomatic patterns and safe abstractions

Comment critical hardware interactions

Unit test where possible, host simulation for logic

Modularize HAL/PAC interactions

Regularly run Clippy and Rustfmt
