cpp_binary_size

This project has the object of collecting interesting C++ examples that impact the resulting binary size of applications, specially on bare metal microcontrollers.

Moreover, this project additionaly provides a build system for comparing, flashing and emulating the generated firmwares.

Dependencies

• CMake >= 3.22
• Ninja
• renode
• puncover
