ASCII to HEX Conversion program in 8085 – PhysicsTeacher

In this post, we will see how to convert a given ASCII Character into its equivalent Hexa Decimal (HEX) number using the 8085 microprocessor program or instruction set.


Algorithm for ASCII to HEX Conversion with 8085 microprocessor

  1. Load the given data in A register
  2. Subtract 30 H from A register
  3. Compare the content of A register with 0A H
  4. If A < 0A H, jump to step6. Else proceed to next step.
  5. Subtract 07 H from A register
  6. Store the result
  7. Terminate the program
