Nate's talk on Real Time Operating Systems! He discusses what a real time operating system is, why we need them, and how we can use them to build responsive, resilient systems.
This was a really great presentation and exactly what I was looking for at the exact level of expertise I wanted. Thank you! Wish you had a better audience ha
It's interesting how he lightly mentioned ESP as a wifi chip and now it's very popular as a complete MCU, cheaper than Arduinos and has a great community.
Just enough detail to point me in the right direction. Thank you for putting the slide deck together. IoT is the next evolution of a connected world and having a good programming stack that can handle networking and security for networking is paramount to ensuring everything works well together in an embedded system. ESP32 is perfect for this type of application for networking between embedded IoT devices and systems. Will pick up some of the low cost embedded systems to play with Free RTOS, especially the Amazon flavour. I see where they're going with IoT. IoT isn't fully mature yet but I have an idea how to do that!!! Exciting times!!!
Nice and quick way explanation (PPT was made for doing these type of stuff 👍, ) But it is better if you provide actual core information behind these RTOS and its terminology, because RTOS is somewhere middle between Embedded and OS computer programming. For beginners and unfamiliar with OS or MCU, This way is difficult.... Overall Nice.... 👍
@15:35 i literally just had an interview question on this and had this video paused right before it. can't go back now, at least i identified the problem though.
within tick period, what will happen if task1 finishes (or get blocked) earlier before the next tick occurs? will an extra scheduler instance happen between the regular tick interval?
For priority inversion you need three tasks. The highest priority task hands resource to lowest. No problem. Lowest runs to completion hands resource back. But if a middle priority task needs the resource while lowest has it. The middle task prompts the lowest a d we get a deadlock... Hence most modern RTOS have priority inheritance which allows the lower priority task to inherit the priority of the task giving the resource and hence will not be preempted by a middle priority task, but an even higher priority task can always preempt.
This is total waste of time. People need to learn basics of making presentation. Stick to the fact, no more monkeying around with irrelevant and trivial fucking with giggles. This is way engineers need to spend their time learning to speak to public. This is why graduates of CalPoly is never taken seriously by peers.
Just because you like to go through life joyless and rigid doesn't mean you get to look down on others for making things fun. It's an intro lecture, would you rather he drone on and on about minutiae? Humor is a key tool for a teacher to keep the attention and gain the respect of their students, as well as foster continued interest and motivation to study.
Who hurt you? This guy did a great job! He managed to be funny while staying on topic. It would be one thing if he completely deviated from the topic, but that wasn't the case. You need to check your ego because you won't make it far with one like that.
Hey this was great! Perfect level of detail. Thanks for sharing 😁👍
Awesome presentation with a really useful Q&A section too!

Great presentation!
Awesome presentation, I really wish to be like him as a presenter in the future.
Nice presentation!
Awesome
Danke.

Great vid :)
Its very good session on RTOS to truly understand the problem RTOS meant to solve.

Great video, only part I don't get is how the beep helping parallels?
Great content. Entertaining.
Spent 20mins on animation 😆.
thank you
This is a neat presentation!!
Is there a way to contact this guy ? His explanation is so crisp and perfect.

I would like to learn more about the robo-ducks

Your question was already answered in the video.
For priority inversion you need three tasks. The highest priority task hands resource to lowest. No problem. Lowest runs to completion hands resource back.

keep it up
Great

Yeh, there are better options than FreeRTOS.
This is total waste of time.

Add unnecessary hate comments to youtube videos and you are sure to be taken seriously by you peers smh
Reading your comment was a total waste of time!!

It was a great presentation and i can relate to it trying to program an esp32 with basic sound-reactive lights.
