Hello Folks,


Overview

Welcome to the 8085 Microprocessor Kit Simulator! This project simulates the functionality of an 8085 microprocessor kit, providing a virtual environment to learn and experiment with microprocessor operations.

NOTE: THIS VERSION DOES NOT INCLUDE ERROR TESTING SO WRITE EVERYTHING CAREFULLY WHILE ENTERING COMMANDS.


HOW TO USE Simulator:

 FOR PC 

Note - if you made a mistake during input you can press '\', for Backspace.



  


    Entering Code

    


      
Type '1' (do not press enter yet)

      
Type 'a' and press 'Enter'

      
It will ask for starting Ram address of code.

      
After Type stating address, Press 'Enter'

      
Now in the screen you will see the starting address and there you will start entering your instructions

      
After Typing instruction press enter, Microprocessor will automatically jump to next address for you to enter next instruction

      
After instering last HLT instruction press reset button

    

  

  


    Entering Data

    


      
Type M (do not press Enter)

      
Type your data address and press Enter

      
After entering data address you will see your data address and previous data stored there(may be garbge)

      
Type your data and press 'Enter'

      
Microprocess after 'Enter' will store data and jump to the next location

      
After data input, press Reset

    

  

  


    Entering Data

    


      
Type M (do not press Enter)

      
Type your data address and press Enter

      
After entering data address you will see your data address and previous data stored there(may be garbge)

      
Type your data and press 'Enter'

      
Microprocess after 'Enter' will store data and jump to the next location

      
After data input, press Reset

    

  

  


    Executing Code

    


      
Type G (do not press Enter)

      
Type your starting code address and press Shift + 4 (for '$' character)

      
After entering code address you will see 'Execution' on screen, which means code is successfully executed.

      
Press Reset

    

  



 FOR MOBILE PHONES 

 

  
Everything is same, Each process is same as PC.

  
There are some changes in Keyboard.

    


    On Mobile devices:-

    


      
'Enter' Key is '.' character

      
For Backslash use '/' character
