Programing a 8051 chip in c - erratic behaviour

erratic behavior

I am programing a 8051 chip in c. I have to use a keypad to increment and decrement numbers. If I push the increment or decrement key to many times (20) the program jumps to another section of code. Sometimes it puts characters all over the screen. Any help would be appreciated.

Re: Erratic Behavior

Are you debounceing the keys properly?

If not, the program may see many keypresses and overflow your buffer.
