Embassy

“Embassy uses this concept of no heap allocation and I find it really solid.”

“I mostly use embassy (embedded microcontroller development) for example.”

“Check out Embassy and you'll be free to ignore pretty almost everything suggested here”

“It's super easy to get started and has been, by far, my favorite way to develop embedded projects.”

“I can focus less on the runtime specifics as they use the same traits and interfaces”

“Combine it with a scheduler like rtic or embassy, and now hardware abstractions are completely taken care of.”

“embassy is a satisfying middle-point between "baremetal" firmware and running something like FreeRTOS / NuttX that hides the event loop from you”

“it's just "in-band" of the language now, and async/await gives you syntax to do it.”

“Writing embedded code with an async-aware programming language is wonderful”

“If you're programming for ESP, then embassy is the way to go in most cases.”

“you'd be hard pressed to come up with a situation which an RTOS could do and embassy-rs's approach would be fundamentally incapable of”

“It has literally split the ecosystem I'm not sure why people think it hasn't.”

“You can 100% do this kind of thing, and you'll probably get better latencies as well.”

“giving hard evidence of how this can be used for real-time tasks”

“It's just split into multiple crate so you don't need to pull in one mega-lump of code for everything.”

“it's actually superfun to have real low-level code working in parallel”

“Highly recommand this stack if you're planning to start working with embedded systems in 2026.”

“The latency of the executor and the compiler-generated async state machines is predictable, so you can use Embassy for hard real-time work.”

“long-lived device tasks that hide timing and coordination behind a small, typed async API”

“I couldn't get my dmic running. Something about PDM being missing.”

“Embassy and async Rust are probably the best things that have happened to the embedded world in the past decade!”

“The embassy scheduler here could run into a problem because long running tasks would block short lived interrupts.”

“people damn near fall to their knees and weep when talking about how nice the experience is using embassy”

“not all of the Embassy examples are set up to work with Nucleo boards”

“it finally feels like embedded is getting a toolchain that is actually modern and better”

“Embassy suffers from being immature with some traits that haven't really been fleshed out sufficiently.”

“you will enjoy quite good latency and jitter characteristics by default”

“with esp-rs and its support for embassy to help me get started!”

“Embassy uses power states efficiently to reduce power draw and temp when nothing is scheduled”

“Have used embassy several times for projects and it's a beautiful work of art.”

“It's clever for sure but there can be variable latency between when the hardware event occurs and when the next step in the task starts.”

“Embassy's executor is quite nice. You get to write much more straightforward linear code, and it's more battery efficient”

“they seem to have built some vaguely pretty decent interfaces and drivers”

“It seemed a little early days with that though, it seemed like the APIs were changing quite a bit”

“its hardware support for STM32, for example, is a step up from the initial generation of Trait-based HALs”

“Embassy (a combination of an async framework and HAL components) is pretty slick if it does what you need.”

“while things like Embassy are a joy to work with, they're missing a lot of”

“You can look at asynch and things like https://github.com/rtic-rs/rtic and https://github.com/embassy-rs/embassy for common embedded patterns.”

“That Embassy exists and its ecosystem as vibrant as it is is, if anything, an unexpected triumph.”

“Looking at embedded-hal and even to extreme embassy you can see the value of it.”
