Description

This course teaches you the foundations of real-time systems and how to build real-time applications using FreeRTOS ,one of the most popular real-time operating systems  for embedded systems.  The course gives a detailed overview of the characteristics of the FreeRTOS real-time kernel,  provides a detailed tutorial on the APIs to implement the various features of FreeRTOS  and then goes on to build about 50 real-time projects .

This course does not assume prior knowledge of real-time systems and application programming. By the end of this course you should be able to build your own multitask FreeRTOS  real-time applications which use all the features of a modern real-time application (such as semaphores, mutexes, event flags, hooks, queues, mailboxes etc )and  test their performance.You should also be able to : Calculate the CPU Utilization of an RTOS, Understand Rate Monotonic Schedulers,port FreeRTOS  to any ARM processor,Understand Round-Robin Schedulers,Understand Weighted-Round-Robin Schedulers, Understand First Come First Served Schedulers,Understand the Internals of an RTOS kernel, Implement and explain popular scheduling algorithms and so much more. Please take a look at the full course curriculum.

My goal was to refresh my knowledge on RTOS. I liked the use of modern tools (STM32Cube, Keil uVision). I know Keil is part of the old course, but I do see it mentioned in job descriptions, so it was good to see that still included. That being said, the old content needs to be trimmed to avoid repetition of concepts. To beginners: the course description says you can use STM32 and Tiva-C boards. In my experience, you would be better off with using the same STM32 board the instructor is using. The Tiva-C can only be used with Keil IDE portion of the course. Even then, it took effort to set it up. Just use STM32 board.

This is by far the best course I have done on Udemy. I created my own scheduler couple of years back, but the way it was explained here is perfect.

The structure of the course seems to be designed for professionals due to it's complexity, but the quality doesn't match the structure. And the Audio level is a headache it is really low.

binary semaphore usage with interrupts was not discussed the actual mutex usage was discussed with binary semaphore instead. mostly binary semaphore is used for synchronization, if more scenarios were covered with tasks with different priority it would have been even more better

Very good and interesting course ! I'm learn in very simple form things, that not was finding in the internet.

This is a great course. The instructor is a seasoned pro. He cuts out the fluff and gives only the important elements required to learn the material as quickly and completely as possible. Excellent course.

The sound is too low. I have turn up all my device to 100%, still can't not hear the teacher's voice clearly.

exllent ,improve voice clarity. increase the volume of the course this course cannot understand the subject,how presentation is good but without voice we cant learn any thing.

This course is a perfect match for me. From the first 4 minutes of the first lecture it starts clarifying the concepts of an Operating System in a straight forward, understandable way. I also enjoy learning from this course lecturer - his teaching style just works for me.

Speaker's voice is too low and the subtitles are not according to what is being said. Someone that does not have the ability to understand spoken English will have a hard time with the subtitles. I am still at the beginning of the course and I will reevaluate it according to the lecture in the end

Sound level is too low. Can't hardly hear the voice. Please edit the videos and make the sound louder.

As I understood, cource will be not more suported. And if you will stuck with a problem, you get no help or answer

The first 14 sessions were really good. But it would have been better if structure of this course is explained a bit more. We initially didn't understand why did CMSIS RTOS2 begin.. And few later sessions were hurried.

Liked the way the author fixed the problem of not printing of text / prinft messages from within the tasks.

This a great course. The audio is too low. Even if I raise the level on my PC to the highest, I barely hear.
