#  Embedded System Project with STM32F1  

##  Overview  

A **comprehensive embedded system** is developed using the **STM32F103RB microcontroller**, combining multiple hardware components and software layers to ensure **efficient control and communication**. This system encompasses **peripheral management**, **display control**, **media playback**, and **protocol encoding/decoding**, resulting in a **feature-rich and modular design**.

##  Project Structure  

- **Application Layer**: High-level control and system logic.  

- **Keypad 4x4**: Interface for **user input** through a 4x4 matrix keypad.  

- **LCD & OLED Display Control**: Functions to manage **LCD** and **OLED screens**, providing **real-time information display**.  

- **MP3 Player**: Module for **audio playback** and media control.  

- **Protocol Buffers (pb)**:  

  - `pb_common.c`: Common utilities for protocol buffer operations.  

  - `pb_encode.c` & `pb_decode.c`: Encoding and decoding data for **efficient communication**.  

- **STM32 HAL & System Files**:  

  - `stm32f1xx_hal_msp.c`, `stm32f1xx_it.c`: **HAL libraries** and **interrupt handling**.  

  - `syscalls.c`, `sysmem.c`, `system_stm32f1xx.c`: **System-level functions** and memory management.  

- **Main Application**: `main.c` – **Central control logic**, initialization, and task management.  

##  Features  

- **Real-time Display**: LCD and OLED integration for **visual feedback**.  

- **Media Playback**: MP3 player module for **audio output**.  

- **User Interaction**: **4x4 Keypad** for manual input.  

- **Protocol Buffers**: **Efficient data serialization** and parsing.  

- **Robust System Management**: **Interrupt handling**, **memory management**, and **system-level configuration**.  

## Tools & Technologies
