i`ve said i need a code because it is my exam.It should be in assembly language or C (important one of them) for 8051 microcontroller.
the exam is that the code should increment and decrement (+1 and -1) the 7- seg display of developed motherboard and increment and decrement (+10 and -10) and alos should clear registers(stack) on previous state (if the state was on 7 seg display 0000 it should be so).
i just need a source code...
