54- ...well, I'll stop here.
Of course, the equivalent knowledge can be obtained by trial-and-error, which would take longer and might result in costly errors and imperfect design. The greater danger here is that a sole developer, without the feedback and interaction of even a small group of capable and experienced programmers could simply burn a lot of time repeating the mistakes made by those who have already trenched that territory.
If the goal is to write a small RTOS on a small but nicely-featured microcontroller, then the C books and the uC/OS book might be a good shove in the right direction. Things start getting complicated if you need to write such things as a full USB stack, PCIe subsystem, graphics drivers, etc.
Depending on how much your course is oriented to electronics vs. the programming side of things, it may not be appropriate, but the first few chapters are about hardware and signals. If the class is built around playing with arduino,say, I think it would be great.
About me: My favorite books is either O'Reilly's Programming Embedded Systems in C/C++ or "An Embedded Software Primer". Perhaps even old, old, old issues of Dr. Dobbs.
I learned programming by doing, not reading endless amounts of theoretical material about it, so any kind of materials that emphasize doing is preferable. I've been going through Udacity's CS253 course and found it neat and very helpful. I've searched around for info about the web-app front end material but none of it really crystallized for me or I just found it to be really boring. Perhaps you know of some better ones?
Any help would be appreciated.
