Control Four 5x7 LED Displays with MAX6952 & AT89C51

Easily drive four 5x7 dot Matrix LED displays using the MAX6952 LED Driver and an AT89C51 Microcontroller - all simulated in Proteus.

This project was completed in 2019 as part of an academic assignment.

✨ Features

• UART-based control of up to 140 LEDs
• Supports ASCII characters (built-in font in MAX6952)
• Configurable brightness and scan limits
• Blink mode support via register settings
• Fully tested in Proteus 8.6 Professional

🛠 Hardware & Software Used

• AT89C51 Microcontroller (8051 family)
• MAX6952 Display Driver IC
• Four 5x7 Common Anode LED Matrices
• Resistors & capacitors for interfacing
• Simulation Tool: Proteus 8 Professional
• Language: C (compiled with Keil compiler)

📜 How It Works

1. Connect AT89C51 to MAX6952
2. Configure MAX6952 registers (Normal Mode, Scan Limit, Intensity)
3. Send ASCII codes to display characters
4. Simulate in Proteus & verify output
