How to generate 16 different led patterns with a single switch?

Suggest the logic...


Thanks in advance.
 

Hello!

You are not accurate enough.
What do you mean by LED patterns?
- A single LED that blinks with 16 different patterns (like the tail light of bicycles that you
can by a single press change from OFF / Blink / Continuous?
- A row of LEDs that you want to change with a single press?
- A combination from both?

ya definitely as mr. doraemon said specify that which kind of pattern you required. only then anyone can understand about yr requirement.
 

8 LEDs connected in a row,the pattern can be both blinking or continuous
 

Hello!

Supposing your LEDs are connected to an output port via a LED driver,
each bit of the port can lit one led. The lighting pattern of your led row can be described
with a single byte. If we represent one lit LED by * and one off led by -, then, for example:
0 -> --------
1 -> -------*
2 -> ------*-
Etc...

You just have to define your led patterns:
Code: 
#define NUM_STATES 16

char Pattern[NUM_STATES] = {
     // Enter your predefined patterns
};

Then you create an interrupt function for the button.

And in the interrupt service routine:

Code: 
void ButtonISR(void) {
    static uint8 index = 0;
    index++;
    if(index == NUM_STATES) index = 0;
    LedPortOut = Pattern[index];
}
