⚡Design and Verification of FPGA-Based Wireless Control and Monitoring System Using WiFi

🌐 Project Overview

This project designs and verifies an FPGA-based wireless control and monitoring system using WiFi connectivity via UART protocol. Implemented in Verilog HDL, the system enables remote control of 8 LEDs and monitoring of two simulated sensor values on the FPGA board.

Commands are received wirelessly through an ESP8266 WiFi module acting as a UART bridge, allowing real-time device management. 🛰️💡

✨ The design features:

• 🧠 UART command parser that interprets instructions like turning LEDs ON/OFF and requesting sensor status.
• 🔄 State machine for UART transmission managing start, data, and end bytes efficiently.
• 🧪 Comprehensive Verilog testbench simulating UART communication for system validation.

🚀 Usage Instructions

1. 🔌 Connect the FPGA to a WiFi-enabled UART bridge (e.g., ESP8266).

2. ⚙️ Load the Verilog design (design.v) onto the FPGA board.

3. 🧪 Run the simulation testbench (testbench.v) to verify system operation.

4. 📲 Send UART commands wirelessly such as:

   • ON1, OF1, ON2, OF2 → Control individual LEDs
   • STATUS → Retrieve sensor data

5. 💡 Observe LED responses on the FPGA and sensor data received via UART terminal.
