is there a way to make a button click and double click?

[hande]

I tried to make it use timers and counters but it didn't work well. please help

[T J]

use a timer interrupt to give a timebase or

I use the Systick,

just add something like this:

mSint = true;

in your foreground process;

if( mSint){

msint = false;

process_key_Detect();

}

here is a rough debouncer.

processKeyDetect(){
if (keydown)
{
 down ++
 up = 0;
}
 
if (keyup)
{
 up ++
 down = 0;
}
if(up >20) we have key release;  up =0;
if(down >20) we have keypress; down =0;
 
}
