Nim works well in embedded contexts. It can compile to C89 or C++ and integrates easily with most any C compiler. I’ve used it with FreeRTOS, Zephyr, and bare metal. It’s a smallish community but there’s a few shipping products using it and the language is really easy to learn if you know C/C++/Python.
Executables from Nim also tend to stay pretty lightweight even when using generics / templates.
