Hi,
you can also use the "when" instruction only true when it is changing state

var Status=0 onevent buttons when button.center == 1 do if Status==1 then Status=0 else Status=1 end end

or the single button event:

onevent button.center if button.center == 1 then if Status==1 then Status=0 else Status=1 end end

Debouncing a button with a short delay to prevent multiple read. The delay does not effect other program parts. This works fine but maybe there is a better way…

var Status = 0 var delay = 0 timer.period[0]= 100 onevent buttons delay += 1 if delay == 32765 then delay = 25 end #prevent from integer overrun if delay > 25 then #wait for 25 cycles until read buttons if button.center == 1 and Status == 0 then Status = 1 delay = 0 #reset counter elseif button.center == 1 and Status == 1 then Status = 0 delay = 0 end end onevent timer0 if Status == 1 then # do something call leds.top (0, 32, 0) # just a visual control else # do something else call leds.top (0,0,0) end
