if you have a specific question we can help you, but if you know very little about 8052 and ask can you help me do a complete project, the answer will be no one can help you, you have to read the 8052 bible before you can even understand a ready made program.
for example if you ask how do I set a port pin to I/P, the answer will be write 1 to it i.e. P0_1 = 1;.
How do I read a port pin using c?
if(P0_1 == 1)
{....do Port0 bit1 = high function..}
else
{....do Port0 Bit1 = low function}
So the trick here is to know C language, then read the getting started manual of keil to know how to use C language extensions for 8052.
So if all these things are written simply in the references pointed out by forum members, why not just read them and be expert on your own.
If things worked, great you taught yourself something, if they didn't , you post your attempts here and we will point out where you went wrong.
So to learn you have to do effort and patience, otherwise you will never learn.
