Hello,
is there anyone who programs in c++ with Lyrat? Why examples in ADF sdk are in C?
Thanks all.
Bye

Why C over C++?

C is traditionally used in embedded because of it lightweight nature. C++ can be rather heavy on memory usage esp with STl.

With C you can control where your memory is allocated - dram or spi ram - very easily with the esp malloc. With C++ and STL it's rather complicated to write a custom allocator to control dram/spi ram allocation.

I use C++ it's great with STL - but you have to do alot of work not to use up all the dram.

ok thank you for your replay.
I like c++ and it is very useful in more complicated project.
But in this case, lyrat, I need to be not expansive with resources.
thank you.

Note that C and C++ are mostly interoperable, and ESP-IDF (the SDK ESP-ADF is built on top of) supports the base C++ language as well. You should be able to write additions for ADF in C++ if you so desire, even if we don't have explicit examples of it.

thank you, for me it is very encouraging.
