A quick deep dive into asynchronous programming in an embedded context with Rust and Embassy

Описание: Diving into asynchronous programming or async/await in an embedded context with the Embassy framework

We take a look at the implementation details of a simple 'blinky' example. More precisely we look at the following

00:00:00 Intro to Async in embedded systems
00:06:19 A brief note on what an Executor is?
00:07:15 What's the Embassy Async Framework?
00:14:09 simplicity of async using blinky example
00:15:59 embassy's main macro expansion
00:18:33 Thread-mode executor implementation
00:23:52 Executor's run-queue impl (linked list)
00:24:50 the Spawner type - spawning tasks to an executor
00:27:20 the TaskStorage abstraction
00:31:30 running our main task, initializing peripherals and setup (quick demo)
00:34:50 Polling futures with the Embassy Executor
00:40:00 No busy-loop polling: sleep when no work using interrupts or WFE/SEV.
00:45:40 Wakers in Embassy
00:50:04 the actual time-driver implementation in the HW abstraction layer
00:53:37 Summary
00:54:00 trading complexity for performance in Async
00:54:40 Conclusion
