VIDEO ERRATA
Forgive me audience, for I have erred...

ERRORS
- 13:52 : The compiler is not actually inserting the panic during the array-access-by-index bounds checking... It's actually the `Index` trait implementation on arrays and slices that will perform the bounds-check logic and invoke the panic macro if necessary. Thanks to @werecatOmega for pointing this out!

CHANGES
- 2:51 : The Crates plugin has been deprecated, replaced with Dependi

OF NOTE
- 5:19 : This series will primarily focus on the 'microcontroller' subset of bare-metal hardware, but for those working with application-class SoCs, @pppgggr notes that the 64-bit Arm v8-A architecture is listed on the Rust platform support page under the `aarch64` target arch.

OMISSIONS
- 5:00 : The nRF52833 has a floating-point unit (FPU), and this is why we opted for the "hard-float" bare-metal target variant of the Arm v7E-M core architecture (thumbv7em-none-eabihf)
- Yes, I am aware of the probe-rs VS Code plugin, and it does look great! I was somewhat conflicted when making the video whether to present the probe-rs + VS code plugin or the "half-way" solution of pairing `cargo embed` with GDB... I figured the `cargo embed`/GDB route might be more helpful for those using a different editor, and/or already used to debugging in GDB. The probe-rs VS Code plugin looks amazing, though by their own admission it's currently in a preproduction/alpha stage: I did try it out, but found the disassembly for my code was jumbled, with some instructions showing up out-of-order, which could leave a newcomer a bit confused... Regardless, I know the probe-rs team is working hard on it, and it definitely has the potential to be the best solution for embedded debugging (plus its Rust all the way down!), so there will be a dedicated video on getting it set up in the future.

This series will be where I finally learn rust

[TheMisterSpok]

This is the most concise and to-the-point embedded rust video I've ever watched. Bravo!

[MrScorpianwarrior]

I have no use for this, I have never written for an embedded machine, but boy do I love your style of content. You go into just the right amount of detail to keep me engaged, and I love learning about this sort of thing.

[ryanbrownie]

This series will be responsible for a next gen of Rust embedded developers . I Love this 🤖

[mikkelens]

This is incredible! I have been searching for this exact series for the last 2 years! No other embedded rust videos are anywhere near as accessible as this, and I'm very excited to see where this goes. Actually showing the "dumb" steps like how to look up the architecture for a basic microcontroller is super essential for not losing people like me who have only touched external-chip development through something like the Arduino IDE or PlatformIO in some primitive C-like language. I finally have a reason to dust off my bootleg Uno device without having to find out of date oversimplified tutorials, downloading sketchy firmware or going using giant vscode extensions.

[isfandyar]

please dont stop this series i want to learn rust for embedded rather than c++ because rust is future in next 10 yrs

[jorgegomezreus]

Best video about embedded rust I've seen, please continue this awesome series!

[MegaDuncz]

Love your work, informative, interesting and professionally edited, hope the channel blows up!

[munzrs]

The quality of this video is just insane. The editing is crisp. The writing makes it so clear. The pacing is quick, but not overwhelming. The scope of the topic allows going into the perfect amount of detail of each item for a beginner. The music... it's perfect. It's so clean and classy. It matches the tone of the vocals and topic so well. The most obvious sub I've ever made.

[Dygear]

I consider this to be the missing Rust Embedded Tutorial. Great job!

[osalem]

This channel is gonna be one of my favourites, keep hardworking on 🔥

[SibylDark]

8:50 Oh brother! Seriously though, really great and methodical walkthrough. Good for newbies too, I think a lot of us in embedded space assume everyone has intimate knowledge of linkers, memory maps, ISAs, vector tables, etc. thet you pick up along the way doing embedded dev. Its great to hear these things explained in context with Rust.

[sudman]

Amazing, This is beyond any tutorial / learning thing that I have ever came across, 20 mins felt like 2, I think am going to be a rust dev because of this series. Keep it up 🔥

[iyadelwy]

You Absolutely Positively HAVE to continue this series!🔥

[tanmay______]

You just gave me the motivation to start learning rust. Trying it embedded will surely be a nice challenge!

[BjarneSvanberg]

I have been eyeballing Rust for embedded systems for far too long. This is just what I need. Love that the information is so dense. Good format. Keep it up 😃👍

[markay]

As a system security researcher trying to dive into embedded systems, this video has been like music to my ears!

[beyonson]

Production quality is off the charts! Gonna enjoy my Sunday by following along, thanks for your work!

[idoben-yair]

I never thought I'd enjoy almost 30 minutes of programming-Kevin-Spacey teaching me embedded Rust. Great content, sir!
