Embedded C on the 8051 Microcontroller — Timer & GPIO

Status Type License

Status note: This repository is currently documentation of completed coursework, not a published source-code project. The original Embedded C files were written for a university embedded systems module (Hochschule Hannover) and are not yet uploaded here. This README describes the project honestly based on the actual work completed; no code shown here is fabricated.

Architecture

Overview

Hardware-level software development in Embedded C for the 8051 microcontroller, focused on timer-driven routines and LED control via GPIO.

Objective

Build practical understanding of register-level microcontroller programming and time-critical, hardware-close software development.

Technologies

Category Tools
MCU 8051
Language Embedded C
Peripherals Timer/Counter, GPIO

Technical Concepts

  • Timer configuration and interrupt handling
  • Register-level programming
  • Digital I/O
  • Time-driven control routines

Approach

  1. Analyze the 8051 architecture and relevant peripheral registers.
  2. Implement timer configuration in Embedded C.
  3. Drive LEDs via GPIO pins.
  4. Test and debug directly on target hardware.

Challenges

  • Working at register level without high-level abstraction.
  • Correct timing calculations for timer configuration.

Skills Demonstrated

  • Embedded C programming
  • Microcontroller fundamentals
  • Working with timers and digital I/O at the hardware level

Possible Extensions

  • Add sensor integration (e.g. temperature or light sensors).
  • Add UART/I2C communication.
  • Port the concepts to a more modern microcontroller (e.g. STM32).
