<div>If you want to go the C route, you might find this useful. Although this is for an outdated language version, the basic pitfalls still apply.</div>

Some of that of course also applies in C++ as they are closely related.</div>
<div> </div>
<div>If you actually do already know C++ well, there's really nothing to be said against using a sane subset of it on bare metal "MCU" targets.<br/>
You need to know what (not) to use and do, of course. (I *could* elaborate)<br/>
Programming "OO" in the way it was taught in Java intro prog class at uni, probably not.</div>
<div> </div>
<div> </div>
<div>I hardly ever bother doing anything in pure C these days, unless it's for a really small target.<br/>
For reference, on a stm32 with 8 KB RAM and 64 KB flash, I might still use C++ and can get a decent amount of functionality in there.<br/>
I don't remember a project, but 4K / 32K, I wouldn't be afraid either. (but may use still less of C++)<br/>
<br/>
I make more or less extensive use of features that need at least C++11, preferably C++14, if not 17, and which current C does not offer.<br/>
The number of contexts where "constexpr" can be used increased from verison to version of what today some call "modern C++",</div>
<div>and this particular feature alone has tremendous impact on my "embedded" projects - it is the savior from the much hated preprocessor macro insanity. (I still use that, but in much fewer, special contexts) Compile-time computation and real constants, that's what almost tips me over to using the word "beautiful" w.r.t. the C++ language. In a limited context, mind you :D<br/>

Thanks Jay, I actually installed a VirtualBox with Ubuntu tonight and started learning C. It is a lot like C++. Hopefully I can pick up on the basics of it pretty quick. At the moment I have been a little confused about the * and ** next to variable names. Also the & variable names. I found some resources about it and realize they indicate pointers or something. I'm just not following the reason to have a pointer instead of the variable. I'm sure it will become clear as I continue to learn. </div>

<p>I was an embedded/bare metal HW/SW engineer and will say working with embedded ARM uCs C.</p>
<p>C++ usually complicates things and is overkill for run of the mill embedded stuff. Don't know if it is still true but at one time the C++ libraries had a lot of bloat and took up a lot of storage. I've also found C++ harder to debug when people start overloading and abstracting things.</p>
<p>If you do need to run object based code you can in C. Take all the data for an object and put it into a structure and then pass a pointer to the structure around through the code. This is more or less the equivalent of a 'this structure' that objects have in C++. The data is isolated to a single object and just use a new structure with different data for another object. Also follow C++ and make you own constructors and destructors to setup and shutdown things.</p>

<div>I am thinking about programming ARM chips like the STM32 for something like Braids. I know that I will not be making my own Braids module anytime soon, but I would like to start thinking about the language I need to learn. I know the most about C++. I also realize that my question may be better asked as what libraries should I load / study up on.</div>
