[PIC] Time controlled switch using PIC18F4550 with MPLAB

[aniketkarajgikar]

I am taking input of start time of any device from keypad and comparing it with current time of RTC. When current time matches RTC, LED will be ON.
I am using following logic.

consider inputs of minutes from keypad as mindecimal and minunit.
mindecimal=readkey();//to read key from keypad
minunit=readkey();//to read key from keypad

and RTC's minute will be
min=get_time(1);// function to read minutes from RTC

Now for comparing,

x=((min&0x70)>>4);
y=mindecimal - 0x30;

p=(min&0x0F);
q=minunit - 0x30;

if(x==y)
{
if(p==q)
{
//glow LED
}
}

But logic not working correctly.
Please Help.
I also want to do it for stop time.
Please Help.
