General Instructions:

1. Enter the desired Stop Value (0–255).

2. Select the Update Frequency in Hz (can be changed anytime).

3. Click on View Circuit Diagram to see how the 8051 and LEDs are connected in logic diagram and block diagram.

4. Click on View Assembly Code to analyse the assembly code used for this experiment.

5. According to your analysis, write your code in the Assembly Code Editor.

6. Click on Check Code to verify your program against the given code.

• a If correct → a success message will appear and Start Simulation will be enabled.
• b If incorrect → you’ll be asked to review and correct your program.

7. (Optional) You can directly copy code into editor by clicking on Use Code in View Assembly Code popup.

8. After validation, click on Start Simulation to run the simulation.

9. Observe the LED pattern and Count. You can change Update Frequency if you want to vary the counting speed.

10. If you want to save your program, click Download Code. It will be stored as binary_counter.asm.

11. Click on Reset Simulation to stop the simulation, clear the editor, and reset everything to default.
