Async Rust vs RTOS showdown!
Summary
A technical comparison of async Rust (Embassy) versus FreeRTOS/C on an STM32F446 MCU, evaluating interrupt latency, program size, RAM usage, and ease of programming. The post includes detailed Rust and C code samples, benchmarks, and concludes that Embassy/Rust generally wins on performance, with RTIC as an addendum showing mixed results.
