8051 Microcontroller – Programming Tutorials, Simulators, Compilers and Programmers

8051 is not just a number, is the name of one of the most advanced microcontroller used in robotics. This single chip microcontroller is a box where are stored many functions like CPU, RAM, ROM, Timer, Serial Communication Interface, I/O ports, etc. First version appeared in 1980s and since then the microcontroller is a popular chip for embedded systems.

The 8051 microcontroller is a small computer based on architecture with support for embedded applications. This is the biggest difference between a microcontroller and microprocessor. A microprocessor is used in personal computers while a microcontroller is used for embedded systems especially in robotics.

Since 8051 is the most common microcontroller designed especially for robots, I decide to write an article with resources for beginners and advanced users. In this article, I include resources for programming, simulation, compile, programmer kits and especially tutorials to learn how the 8051 microcontroller is programmed or simulated.

8051 Microcontroller Programming Tutorials

Beginners or advanced users can read these tutorials for educational purposes to learn how to programming a 8051 microcontroller or used for inspiration in case of advanced users.

Simulators

Useful tools designed to be used in development process for 8051 microcontrollers.
  • Raisonance – application simulator for 8051 microcontrollers.
  • JSIM51 – free simulator for 8051 microcontroller and one of the most popular simulator with comprehensive documentation to learn how can be used.
  • Micro C 8051 – simulator C and assembly programming language compatible.
  • C51 Software – simulator tool for classic and extended 8051 microcontrollers.
  • Proteus VSM for 8051 – complete tools for develop and test programming line for all series of 8051 microcontrollers.
  • Crossware 8051 – simulation tool that creates a virtual clone of 8051 microcontroller that runs on computers.
  • EdSim51 – one of the most popular simulator tool for 8051 series with interface for virtual peripherals and keyboard, ADC, or DAC.
  • Tiny 8051 Microcontroller Simulator 0.6.1 – designed for educational purposes, Tiny is a simulator written in C# programming language for simulation and debugging.

Compilers

List with C or C++ compilers and support for 8051 microcontroller series.
  • SDCC – C compiler for a wide series of microcontrollers including the 8051 model.
  • mikroC PRO for 8051 -C compiler with friendly interface and support for Atmel and Silicon Labs microcontrollers.
  • Keil – powerful and efficient C simulator for 8051.
  • TASKING – compiler compatible with 8, 16 and 32-bit microcontrollers.
  • IAR Embedded Workbench for 8051 – C and C++ compiler for 8051.
  • 8051 C Compiler – based on ANSI standard, the Crossware 8051 C compiler is designed for 8051 microcontroller series.
  • 8051 C++ Compiler – C++ simulator with support for object oriented programs.
  • Ceibo 8051 C++ – C++ compiler with support for Object Oriented Programming and used for debugging and code maintenance.
  • 8051 C-Compiler uC51 – friendly interface tool based on ANSI C standard.

Programmer

In this section I made a list with hardware devices called programmer and used to write in the 8051 microcontroller memory the machine language code.

8051 Microcontroller Instructions Set

For a precise control, the microcontrollers may operate under instructions. These instructions are commands written for microcontroller and divided into various categories including arithmetic, logic, data transfer, Boolean variables, and machine control instructions.
