Serial Communication Protocols

This repository provides an overview and implementation examples of popular Serial Communication Protocols used in embedded systems and digital electronics.

---

📦 Protocols Covered

• UART (Universal Asynchronous Receiver Transmitter)
• SPI (Serial Peripheral Interface)
• I2C (Inter-Integrated Circuit)

Each protocol includes:

• Verilog or C implementations
• Simulation testbenches
• Notes on hardware interfacing (optional)

💡 Key Concepts

UART

• Asynchronous protocol
• Uses start/stop bits
• No clock line required

SPI

• Synchronous protocol
• Full-duplex communication
• Uses MISO, MOSI, SCLK, and SS lines

I2C

• Synchronous, half-duplex
• Uses SDA (data) and SCL (clock)
• Supports multi-master and multi-slave

---

🧪 Simulation & Testing

• Simulated using ModelSim and Quartus Prime
• Testbenches provided
• Functional and timing verification

---

📁 Requirements

• Verilog/SystemVerilog support
• Intel Quartus Prime (Lite or Standard)
• ModelSim or compatible simulator
• (Optional) FPGA development board
