why this dont work in real simulation. :( help me

Hello,

Please can you provide some more information?
Which controller do you use?
What behavior did you observe?
What exactly is not working in your code?

Best regards.

im using a 16f877. in Proteus this works fine. but in real i cant light an led for each and every keypad button. but in relal this dont happen. im building a bike dock system. i need a passcode lock for 4 users.

Hello,

Do you use development system or custom PCB?
I have tested this on EasyPIC7 and it works fine.

Best regards.

[nayantha88]

i am using a developed circuit. i think the problem is in my circuit or my programmer.
Thank you very much
