    Default pic16f887 clock project, need help

    I am trying to set the time of my clock with a key pad. I start a loop by pressing the * which sends it to my hours loop which starts checking for my key pad inputs. Like if num1=1 then hour=1 or if num1 & num0=1 then hour=10. The problem is when i get to minutes and you have to numbers like 21 and 12 i dont what i can do to distinguish between the two.Another problem is when you get double digits like 11 or 22.

    Also is there an better way to do this without doing TONS of if thens.

    Code:
    @ ERRORLEVEL -306
    
     
    
    
    
    digit1 var portc.6'portd.0
    digit2 var portc.4'portd.1
    digit3 var portc.5'portd.2
    digit4 var portc.7'portd.3

    Default Re: pic16f887 clock project, need help

    minutes and you have to numbers like 21
    (2*10)+1
    minT VAR BYTE
    minO VAR BYTE
    minT = 2*10
    minO = 1
    minT + minO
