Logic-Circuit-C — ATmega32 Learning Code & Projects

ATmega32 firmware exercises and mini-projects in C — written while learning embedded C, with Proteus simulations alongside the code.

Projects

Folder	What
Learning/	Basics: 7-seg display, 7-seg with button & interrupts, keypad, LCD — each with .pdsprj Proteus simulation + C source
PasswordChecker/	Keypad password checker on ATmega32 (passwordchecker.c)
fourLEDP/	Parallel-port 4-LED patterns (parallel.c) + simulation

Toolchain

• MCU: ATmega32 (AVR)
• Language: C (Atmel Studio project files included)
• Simulation: Proteus (.pdsprj per exercise)

How to use

1. Open the .pdsprj in Proteus to see the circuit.
2. Load the matching .hex from the Debug/Exe folder — or rebuild the .c source in Atmel Studio.
3. Run the simulation: buttons/keypad drive the firmware exactly like real hardware.
