This article explores the world of asynchronous Rust programming specifically designed for microcontrollers. It delves into the inner workings of Futures, cooperative scheduling, and Async Rust executors, explaining their importance in optimizing resource utilization. The article also introduces the Rust Embassy project, a framework that unlocks the power of asynchronous programming on microcontrollers. It assumes prior knowledge of Rust and using Rust on microcontrollers. Asynchronous programming is discussed, highlighting its ability to handle concurrent tasks effectively and optimize resource utilization. The article also compares preemptive scheduling with cooperative scheduling and discusses the role of executors in asynchronous systems. The Embassy is mentioned as a popular async executor for embedded systems.
