Digital Code Lock With 3310 LCD

It seems like your code get stuck while simulation.

as when you write data on eeprom, you wait for data to be verified by acknowledgment from EEPROM.

check you write_ee function on line 112 of code

  while(EE_D==0) ;					/* Wait until data verify	*/

So if EEPROM is not connected in simulation you wont get any ack from EEPROM so program is stuck forever there.

Dear MAJOKA
Dear
I am tray with 24c02
In proteus I thank work
But actual on board not save password in 24c02
I send proteus file and complete code
Plz chak it

protues file

check connections once
and in program ur writing in eeprom after that ur reading and storing it now how u can say it read correctly because u can't see
use hyper terminal and send it to serial port and see the readed result on terminal in Proteus so that u verify that it work

i am many time check connections but password not save in 24c02

then it is not working in Proteus also
save them and read again and then see it on hyper terminal to verify that code is saving
