C++ in Embedded Systems: Modern Practices for Resource-Constrained Environments

  • C++ is preferred over C for embedded systems due to modern features and tools that can help optimize resources.
  • Modern C++ standards like C++11, C++14, C++17, and C++20 provide smart pointers, constexpr, templates, and std::chrono for efficient embedded programming.
  • Smart pointers from C++11 help in handling memory cleanup automatically, constexpr allows pushing work to compile time, templates aid in writing flexible code without runtime cost, and std::chrono is useful for real-time functions.
  • While C++ offers powerful features for embedded systems, some aspects like heavy exception handling may not be suitable, and it is commonly paired with other tools like pointers and bitwise operations for hardware interactions.
