LED + BUTTON + INTERRUPTS ?

[Guest]

Hi !

I would like to use a PIC18F458 that has a button (on RB4) to switch on a led (on A0, for example) if the button is pressed for 4 seconds and not if not. =)

Do i better have to use interrupts ? Or something else ?
Do you have a program to help me ?

Thanks a lot.
Best regards.

You will see that this forum is plenty of proposal like yours, the idea is
that you must do the first movement posting a small but complete
C source code to enable us to know what and how are you
trying to do it.
If you tried starting with the examples provided with the CCS compiler
package I´m sure you are ready for this. Once you post your code we will
correct, criticize and propose some tips to guide you.

Best wishes,

Humberto
