Interoperability with C
Code examples from previous chapters that you were able to run in a Renode simulator are using both C++ and C code. We used vendor provided HAL library and Common Microcontroller Software Interface Standard (CMSIS) by Arm, both written in C and contained in the platform folder.
If you take a look at the CMakeLists.txt file and the add_executable function in it, you will see listed C files from the platform folder and just a few C++ files. Building a project will provide the following console output:
