From Zero to Async in Embedded Rust

Today we learn about async/await and how it works in an embedded environment by... building an async runtime from scratch in embedded Rust! We also cover time-keeping, state-machines, interrupts and futures.. and a smidge of embassy, which we'll use extensively in future videos.
