Initially it seemed easy and what I already knew... but the week 3 and 4 had alot of new and interesting stuff. It was great eventually... Especially the OS part and some practicals

Excellent introduction to Embedded Systems development that could serve as platform for further studies and research. A valuable pedagogy.

It is a good course, but I think lacks something worth to make it great. There were times when I was very bored about how the e

the last weeks assignment need more detail and instruction, it is not hard , but i belive the guidance is too vague to understand

The course is a shallow introduction to a set of topics about embedded systems, it tries to cover too much without really explaining the concepts. The videos could have some diagram.

I found this course to be dry. No practical examples. Just information presentation, like reading from a book. The lectures do not prepare you very well for the Quizzes and even less for the assignments. This is the only course in Coursera that really got me disappointed. Since there are not many students in this course one might feel a bit "left alone".

In first three weeks the topics covered are not covered in much detail, but it is good enough to get started, and you can learn about that topics from other sources. The reason I am giving such a low rating to this course was, first I expected much more in depth knowledge and wide coverage of topics, and secondly the most important reason is that the week 4 of course sucks, there is no detail, no sources to understand topics, the forums are down right dead and there is no help from the staff (TAs) and faculty, the assignments of week 4 are not clear in terms of what to do and how to do, and it is very difficult to find relevant information on-line. In my opinion you should take this course only when:
1) You already have a clear understanding of C, OS concepts.
2) You are ready to search on-line for the topics taught even when you have no idea where you should start.
3) You have zero expectations from TAs and forums.

Main issues I encountered in the course:
- many videos end with a suggestion to "refer to the suggested materials for more information". Which are these materials, and where can they be found?
- the slides could use some diagrams here and there, as the constant text screens are monotonous and make understanding harder in some cases
- the course does not settle on a balance between breadth and depth of information. Some aspects are presented at a very high level, yet using very specialised terminology and concepts. For instance, context switching when describing the disadvantages of microkernels, or pre-emptively scheduled systems - I have a CS background and had no problem with these aspects, but I am aware I am highly subjective. It's a case of "chicken and egg", where if you understand the low level concepts you probably don't need the course, and if you don't understand them you also can't understand the high level concepts.
- At the end of the Week 3 videos describing the three OSs, it is said "In order to know the details on how to write a program and run applications in Riot/Contiki/TinyOS, please come back to our lectures who have more detailed videos."
Which lectures are these, and where can they be found?
- the only practical exercises in the course (Week 4) are only vaguely related to the course's targets
All this being said, it is an ok introduction to the embedded OS world, if you bring your own CS and OS background knowledge.

The course is for people having advanced knowledge in embedded architecture and knowledge. Until 3rd week is perfectly alright. But from 4th week the course changes to advanced knowledge. I do not think an intermediate could easily grasp enough knowledge from the 4th week. Kindly do the needful to change it.

The ContikiOS is not a suitable for IOT for now. It is too expensive

Useless bla-bla-bla in general words. Nothing concrete. It is not possible to build embedded system with OS after finishing it. IoT is mentioned just for marketing and promotion. If you seriously consider developing OS-based embedded system even just reading Wiki pages about EOS would not be such a waste of time as listening to this course.

NOT GOOD..REALLY BORING

Theory ..theory...theory.... into the 4th week...too dull and boring. The instructor could just have written a book or something about this.

I categorize this course in the beginner level not intermediate.

I wasn't very happy.
The subject material was very shallow; brief overviews of some aspects of the material with repeated references to "suggested materials" that didn't actually exist.
Even at the level of detail presented, there was a lot of info on slides that did not appear in the transcripts. It would have been useful to have the slides be downloadable.
I didn't like the design of the quizzes; this might be a coursera thing (I've seen the same thing in other classes), but the inclusion of 5 subparts of a one-point question meant no "partial credit", making a "5-question" quiz (with 20-odd things to get wrong/right) a lot more difficult to pass than they should have been. (In other MOOCs, I've seen such multi-part questions handled by having the question as a whole be worth 5 points (for a 5-subpart question), and you get a point awarded for each subpart you get right, and not awarded for each one you get wrong (whether it should have been checked and wasn't or should have been not-checked and was.)
There was no interaction with "staff" on the class forums. The "extra thought" topics were simplistic and only barely related to the class materials, and the participation that happened was ... poor, like people thought they were getting points for "taking part" even if all they said was "I don't know."
The professor seemed to have some strong opinions about "controversial" subjects, presented as facts, that I happen to disagree with, and didn't really have any supporting material. (The big one for me was "FPGAs are lower power than MCUs." Which I asked about on the forums, and was never answered. But also several several cases of "the advantage of XX os is that it has small memory requirements", followed nearly immediately by several examples of other OSes described as even smaller.)
Finally, for a 4-week class where the first 3 weeks have only short quizzes, I thought the "week 4" assignment: "download a VM and set up Contiki/cooja, write two programs and get them both peer reviewed by the end of the week" was unrealistic. Especially without "supported matierals", tutorials on setup, or even copies of the sketchy instructions on the slides in the video. (I might not have been awful, given an extra week to complete. I gave up, though.) (existing forum message from a prior iteration of the class says "don't use contiki 3.0 like the instructor talks about, or even 2.7 that he mentions. Go all the way back to 2.6.1...")
There was some interesting stuff there. The lack of "suggested materials" and downloadable slides were the biggest problems.

I do not recommend this course if you want to be taught intuitively. The slides are mostly just a list of bullet points, with very few intuitive figures or charts (normally figures/charts are easier to understand and remember, even the simple ones). You are just fed with lots of concepts throughout the course. But in the end, you are suddenly required to do some practical C programming in Contiki (an embedded OS), which you need to spend some time to figure out quite a number of practical issues just for a successful run.
