GoKawiilBenchmark pits Embassy/Rust against FreeRTOS/C on STM32F446 microcontroller
A technical blog post compares two embedded RTOS approaches—Embassy running async Rust and FreeRTOS running C—on the same STM32F446ZET6 chip clocked at 180MHz. Both implementations run equivalent applications and are measured for interrupt latency, program size, RAM usage and programming ease, using an oscilloscope for timing measurements.
