Nor problem here. Easily done.



Please confirm if you are coding in assembly or C language. If it is the former, then I feel it may be VERY difficult if not impossible. If its the later, then there should be no problem if you have a right compiler like the Keil C51.

But let me tell you, this is a very ambitious project for someone who is "still not confident" with 8051. If I were you, the right thing to do immediatley is to get the keypad and display working the way it works in a calculator. Right entry, left shift , clear on pressing C/CE and such.
