Debounce

[slahiri]

Guys,
I am looking for good Debounce routine Or just use delay_ms(100) after an event. Just to let you know, you guys are very helpful.
Thanks.

Use this in a loop that you pass through many times per second. Basicly scanning the inputs a a fast rate. Adjust the values that show +-15 to adjust the debounc period. This is great for real time applications where you dont want to use a delay anywhere because that is just dead time. This is very resistant to electronic noise.

int1 C0;
signed int8 debounce_counter_C0;

if (input(PIN_C0))
{ if ( ++debounce_counter_C0 > 15 )
{ C0= 1;
debounce_counter_C0 = 15;
}
else
{ if ( --debounce_counter_C0 < -15 )
{ C0 = 0;
debounce_counter_C0 = -15;
}
}
