Hello Friends,
I have interface keypad (4x4) with PIC16F877 using Hi-tech C compiler.
Now I want to scan the keypad to know that is any key pressed or not???
How can I use timer to scan the keypad so that I did not need to scan the keypad every time in program code???
I think I can use timer to scan the keypad but I dont know how to use it..
Please suggest me.... Thank you in advance...
