STM32 Embedded C++ Project 🚀

Overview 🌐

This repository demonstrates the application of C++ in embedded systems, specifically using STM32 microcontrollers. The goal is to provide a learning resource for developers transitioning from general C++ programming to embedded development. The project includes core components, hardware drivers, and practical examples, all aimed at showcasing the capabilities of STM32 microcontrollers and the efficiency of C++ in embedded programming.

Memory Mapped I/O 🧠

In this project, I aim to implement Memory Mapped I/O (MMIO) for hardware interaction. MMIO maps peripheral control registers to specific memory addresses, allowing direct read/write operations on hardware registers through standard memory access instructions.

Memory Mapped I/O involves assigning a fixed range of memory addresses to hardware peripherals. Each peripheral has a set of registers that control its operation, and these registers are accessed by reading from or writing to the corresponding memory addresses. This method allows software to interact with hardware as if it were interacting with standard memory.

Benefits of Memory Mapped I/O:

1. Efficiency: Directly accessing hardware registers via memory addresses eliminates the overhead associated with traditional I/O instructions, resulting in faster and more efficient hardware interactions.

2. Simplicity: Using pointers to access memory-mapped registers simplifies code, making it easier to read, write, and maintain.

3. Flexibility: MMIO allows for fine-grained control over hardware, enabling precise manipulation of peripheral settings and states.

4. Portability: Code using MMIO can be easily adapted to different microcontrollers with similar memory-mapped architectures by adjusting base addresses.

By using Memory Mapped I/O, we can leverage the full power of the STM32 microcontroller's hardware capabilities while maintaining efficient and readable code.
