Touch sensor interrupts when pressed for 2 seconds

[nanogear]

Hello,

I have this code:

#PICAXE 08M2
symbol TOUCHCONFIG = %00001001
;time = 0
main:	
      ;pause 100
      touch16 [TOUCHCONFIG], C.4,w0	
	if w0 > 3600 and time = 2 then 
	   goto subrutine		                  
	   else 
	   goto main 
	endif
	return
	
subrutine: 
           low B.2
           pause 2000
           high B.2 , B.0
           time = 0
           do
               touch16 [TOUCHCONFIG], C.4,w0	
	         if w0 > 3600 then 
           loop
           end if
           goto main

Is just a process that when a touch sensor is pressed for two seconds then execute a subrutine.

But I have a problem. The code jump to subrutine after 2 seconds only if I initialize the picaxe with the touch sensor pressed. In other words, when w0 > 3600 from the beginning. And if I initialize the picaxe and then touch the sensor, the code doesn't jump to subrutine as wished. I know is a code issue... please someone can tell me what is wrong with my code or what is mssing???


thank you so much!

If the program is started, you leave it ten seconds, then press and hold the touch sensor, the 'time' variable will hold a value 10 or more. The test ...

if w0 > 3600 and time = 2 then

Will never be true; time will not be 2.

The 'time' variable is measuring elapsed program time, not the time the touch sensor is held for. You need something like ...

Touch ...
If w0 > 3600 Then
  If time >= 2 Then
    Goto Pressed
  End If
Else
  time = 0
End If

Hippy, you always helping me. Thank you!!! Didn't noticed the issue about the time variable.
