Embassy is one of those impressive Rust projects where I was constantly going "Wait, it can do THAT?" the first time I started looking into it. Like egui, serde, sqlx, typst, and a few others.

This channel is such a fantastic resource for people interested in using Rust on microcontrollers, than you for making such nicely produced videos!!

[oxereviscerator]

this is the best tutorial video i have ever seen

[PigeonOvO]

Whenever I see a new video of yours, my hands are very fast! I love these videos!!!

[Kfoo-djmd]

Your videos a work of art, they are very useful, and fun to watch

I've been going through Embassy lately for some 3D printing hardware I'm building, and it's been great. I'd love to learn more about building device independent crates for interacting with external peripherals, such as over i2c or SPI. Perhaps building our own interrupt handlers that callback to the Embassy executor. I feel like there are some gaps in my knowledge that I know you'd be great at teaching. Thanks for the videos so far; this series has been extremely resourceful in helping me get through the steep learning curve of the language!

Nice to have you back with a great video! This one was easier to digest and I learned somethign new again. Can't wait for the next uploads.

Well explained. I'll give it a shot in the weekend. I hope it turns out better than my first use of Embassy.

This is a great video, I could watch Your stuff all day.

[clivedsouza]

This is great stuff here! I just need to read up on the semantic differences between a task and a future as you mentioned, but overall I am so glad the ecosystem is at such a rich point. Thanks Chris!

I thought at first in your temperature example you were going to do the classic "wait for signal receive, take measurement, show measurement" using a `while let Ok(v) = SIGNAL.wait().await {}`. But instead you made it about polling speed, which is a cool difference. Nice video, thanks for making it.

It's like a tutorial to messing around.

You showed how to mess around, and how to advance to the next step fast.

Also loved the background music

Wowawewa! You're the best! This is exactly what I was looking for—excellent vibe and explanation!

[robwells]

This was such a great video. Plenty of detail and explanation without getting bogged down, and examples that were quick to grasp. Thanks!

Embassy is such pleasant name. I’m so used to new Rust frameworks having names like “gremlin” or “gorlok” or “yucky”.

[alexheslop]

Knocked it out of the park yet again, thanks for the video!

[davidbronke]

Thank you so much for making this! I just recently started helping out with RMK, which uses Embassy, and I love your videos! The clarity is incredibly helpful.

[amidamarurookie]

love your contents you made! Im starting learning embedded systems recently, completely a newbie in this field and really learnt a lot here. Thank you so much The Rusty Bits.❤

[tiagomello]

That’s amazing! Please, keep up the good work!

Hi there, I just discovered your channel, and the videos are fantastically informative! I've subscribed, and I'm eagerly awaiting the next video(s). I'd love to see more videos on Embassy. Another topic I'd like to see explored is unit testing for an embedded target in the no_std environment. From my limited research in that area, it appears to be a can of worms.
