  Do you want the content of nMag or do you want the adress, so that you can access it directly?
  Currently you will get the content of nMag. So each time you want to know what the state of nMag is, you have to call leernMag.
  
  Variable A will be always empty (= 0), as you have a waitcnt(clkfreq*2+cnt) in the code that should obtain nMag, but you have a waitcnt(clkfreq*10+cnt) inside of arrancar.

  I want the content of nMag (1, 2, 3 or 4).
  How can I get the solution? I don't understand what you say me about the times

  You call sensorMagnetico.arrancar, which will start a new COG with the testearMagnetico running.
  sensorMagnetico.arrancar will return immediately - not waiting for the new COG to be started AND not waiting for testearMagnetico which waits 10 seconds.
  So, after 2 seconds you read nMag, but after 10 seconds it will be written by testearMagnetico for the first time. That's the problem.

  And how can I solve it?

  I don't speak spanish, so I cant read the comment above the waitcnt, but I suppose the testearMagnetico waits for 10 sec for a good reason?!
  
  So, the fix would be : wait for at least 11 sec before you call leernMag for the first time.
  
  sensorMagnetico.arrancar
  waitcnt(clkfreq*12 + cnt)
  A:=sensorMagnetico.leernMag

  Hi.
  
  i do speak spanish.
  
  let's see if i can help you with my poor english [noparse]:)[/noparse]
  
  
  

  'Rutina en forma de bucle que se encarga de chequear de forma continua si el sensor detecta un nivel
  waitcnt(clkfreq*10 + cnt)
  
    repeat
  
  
  

  
  
  
  
  The comment says, in other words "continous loop to validating if the level sensor detects a level raising"
  
  IMOO, besides the code posted by @MagIO2, i'd put all the pin settings on sensormagnetico.arrancar routine
  
  
  

  PUB arrancar
      'Reservamos el uso de un cog para la rutina testeo asignandole un espacio en pila
      'Metodo que me reserva el uso de un nuevo cog, haciendo llamada a la rutina parpadeo
      'y reservando un espacio de memoria en la pila
  
      DirA[noparse][[/noparse]14]:=0 'Patita del sensor magnetico 1 configurada como entrada
      DirA[noparse][[/noparse]13]:=0 'Patita del sensor magnetico 2 configurada como entrada   
      DirA[noparse][[/noparse]12]:=0 'Patita del sensor magnetico 3 configurada como entrada   
      DirA[noparse][[/noparse]11]:=0 'Patita del sensor magnetico 4 configurada como entrada   
      DirA[noparse][[/noparse]16]~~  'LED VERDE
  
      cognew(testearMagnetico,@sensorStack)
  
  
  

  
  
  
  
  
  Regards
  
  Heich

  Nope, pin setting was correct. Please remember, each COG has it's own set of dira and outa registers. So, YOU HAVE TO set the pins as output in the COG that uses these pins! Only thing is ... for input pins it makes no difference, as the DIRA of each COG is initialized as input.

  hooktxu speaks Spanish, so you can jabber away to him if you know the language.

  Hola HookTxU,
  
  Le aconsejo cambiar su co'digo a eso de abajo....
  

  CON
    _clkmode = xtal1 + pll16x
    _xinfreq = 5_000_000
    High = 1
    Low = 0
    Out = %1
     
  OBJ
    iWifi : "iWiFiXXX"
   
  VAR
    long sensorStack[noparse][[/noparse]20]
    byte readed
    byte nMag
    byte Cog
   
  PUB arrancar:OK
  'Reservamos el uso de un cog para la rutina testeo asignandole un espacio en pila
  'Metodo que me reserva el uso de un nuevo cog, haciendo llamada a la rutina parpadeo
  'y reservando un espacio de memoria en la pila
    Stop
    OK := Cog:= cognew(testearMagnetico,@sensorStack)+1
   
  Pub Stop
    if Cog
      CogStop(Cog~ - 1)
   
  PUB leernMag|T
    T := ClkFreq*12+Cnt
    repeat until Readed or cnt => T
    if cnt => T
       return 0
    else   
       return nMag
     
  Pri testearMagnetico|i 
    DirA[noparse][[/noparse]14..11]~ 'Patita del sensor magnetico 1..4 configurada como entrada
    DirA[noparse][[/noparse]16]~~  'LED VERDE
    'Rutina en forma de bucle que se encarga de chequear de forma continua si el sensor detecta un nivel
    waitcnt(clkfreq*10 + cnt)
    repeat
      Readed~
      repeat i from 0 to 3
        if(InA[noparse][[/noparse]14-i]==0)
          waitcnt(18_000_000+cnt)
          outa[noparse][[/noparse]16] := High
          nMag:=i+1
          ''iWifi.compassServerConnection(0,1)
          readed:=1
        elseif(InA[noparse][[/noparse]14-i]==1)
          waitcnt(40*12_000_000+cnt)
          outa[noparse][[/noparse]16] := Low
  

  
  Asi esto
  ··· sensorMagnetico.arrancar
  ··· waitcnt(clkfreq*2·+·cnt)
  ··· A:=sensorMagnetico.leernMag
  
  
  Siempre returnara' o Zero or el numero 1..4 depende si Readed esta' uno o no....
  
  Samuel
