Dear RIOT developers,
What are your opinions on writing device drivers or system modules in C++?
I know some of the more constrained platforms might not yet have C++
support, but still it might be an interesting option for some device
drivers. C++ objects for example can be used as an alternative to the
device descriptor pattern we are using in many drivers.
I don't have any particular driver in mind, I just want to hear any
opinions around the community.

Hey,
What are your opinions on writing device drivers or system modules in C++?
Well, there are probably many things that could be written with more
concise code or with less duplication in C++.
But I still think that the base system should be plain C, to keep it
more portable, to better understand how stuff interacts, to "know what's
going on" under the hood, to more easily understand where our precious
bytes get eaten, ...
So I'd be reluctant to change any of the core interfaces to use C++.

Hi,

Please under no circumstances. Is there something worse, how about APL or Pascal?

What's wrong with the "device descriptor"? Is the CPP Object something else? The scope in which CPP would be used for RIOT, is just an extension of C with poor readability and design.

It is noteworthy that this discussion occurs repeatedly in open source projects. It's pretty much my opinion about CPP (except for verbal abuse):
