Do you want to learn about microcontrollers and embedded systems?
Are you studying the 8051 microcontroller?
Do you want to test your code for communicating with
peripherals without having to first build the hardware?
Are you teaching an embedded systems course and would
like your students to have access to a virtual 8051 training kit?
If the answer to any or all of the above is yes,
then you’ve come to the right place.
The EdSim51 Simulator for the popular 8051 microcontroller
is exactly the tool you need.
And it’s FREE!

A virtual 8051 is interfaced with virtual peripherals such as a keypad,
motor, display, UART, etc.

The student can write 8051 assembly code, step through the code and observe
the effects each line has on the internal memory and the external peripherals.

The Virtual Peripherals

  • Analogue-to-Digital Converter (ADC)
  • Comparator
  • UART
  • 4 Multiplexed 7-segment Displays
  • 4 × 3 Keypad
  • 8 LEDs
  • DC Motor
  • 8 Switches
  • Digital-to-Analogue Converter (DAC) – displayed on oscilloscope
