emulator-8051

This is a very old project from my high school days, and probably my very first programming project. The goal was to create a tool for students to practice programming the 8051 microcontroller. The emulator parses ASM-like input code and simulates the execution of instructions, updating various virtual devices such as LEDs, a stepper motor, 7-segment displays, and reading binary inputs from virtual buttons.

Features

• Emulates the 8051 microcontroller instruction set.
• Parses and executes assembly-like code from text files.
• Simulates virtual hardware:
  • LEDs
  • Stepper motor
  • 7-segment LED display
  • Binary input buttons
• Includes example programs demonstrating the use of the emulator and virtual devices.

Project Structure

• emulator.cpp, emulator.h: Main emulator logic and UI.
• Unit1.cpp, Unit1.h: Core processor emulation.
• Unit2.cpp, Unit2.h: Virtual device: Trainer board.
• Unit3.cpp, Unit3.h: Virtual device: Application 3.
• Unit4.cpp, Unit4.h: Virtual device: Application 5.
• C_ExternalDevices.cpp, C_ExternalDevices.h: Interface for connecting virtual devices.
• *.TXT: Example programs for the emulator.
• screenshot/: Screenshots of the emulator UI.

Notes

• This project was developed with Borland C++ Builder and uses VCL for the UI.
• It is unlikely to work on modern systems without significant modification.
• The code is preserved here for archival purposes as an example of my earliest programming experience.
