Hi Dexter and all, my name is Sid.
I recently joined the group and I am also a member of another electronics group where someone posted a question about this project.
#include <reg51.H> //……………….headder file
#include <stdio.h> //……………….headder file
#include <string.h> //……………….headder file
Question: Are the incude files included with the compiler for this particular micro?
Maybe that could be why some are having trouble compiling the code.
Just an observation.

So still no solution has been posted to the problem point out by some users long back.
Keil shows that the code has zero errors and warnings but after running the simulation in proteus, the system is doing the job itself. The user is not asked for the password, everything is taking place automatically..
PLZZZ HELP!!. desperately in need of a solution! TIA.May 11, 2014 at 2:23 pm #11717asfandyarParticipant
