hello everyone! plz help in my project. I am trying to make an electronic lock. This Electronic Code Lock uses a 12-keys keypad that is used to enter a password and open an electric lock or any other device with a signal. Uses an 8-pin PIC 12F629.
I thought of preparing it in mplab software.

The problem is that i m completely new to pic microcontrollr. i am studyin 8085 micro processor in college. i downloaded sum tutorials of pic but m completely in fix. i really jst dont knw from where 2 strt in order to prgram the pic microcontrllr in mplab. So sirs n madams present out here plz plz show me the way. i wll b highly grateful...
 

Hi , Its better to use pic controller with EEPROM build inside(eg:pIC16F877), so that you store your password inside the EEPROM.

minimum requirement for your project: pic controller with EEPROM &atleast 2 PORT(16 PINS). I PORT for key pad (4x3) and other port to activate the lock.
you can also use use lcd to tell the user to interface with your electronic lock. any other help ,reply . i can help u..
 

hello..is there someone who can help me..
-whenever i am running my progame using the pic16f877 it is giving me following errors..

1>ICDWarn0020: Invalid target device id (expected=0x71, read=0x0)
2>Executable code and data must be defined in an appropriate
3>sectionSymbol not previously defined (L00F7)
