Sensor magnetico

Alguien ha trabajado con algun sensor magnetico o algo parecido junto con el propeller?

I have got this code for a magentic sensor and it doesn´t work.

CON

  _xinfreq = 5_000_000                      
  _clkmode = xtal1 | pll16x

OBJ

   serie:"FullDuplexSerialPlus"
   
PUB inicio

  serie.start(-1,30,0,9600)
  
  DirA[noparse][[/noparse]13]:=0 'Patita del sensor magnetico configurada como entrada
  dira[noparse][[/noparse]16]:=1 'LED Verde del sensor magnetico

  waitcnt(clkfreq*10 + cnt)

  repeat
    if(InA[noparse][[/noparse]13]==0)
      serie.str(String("Entra en IF"))
      waitcnt(12_000_000 + cnt)     
      outa[noparse][[/noparse]16] := 1 ' Enciende el LED (n)
      waitcnt(clkfreq*2 + cnt) 

    elseif(InA[noparse][[/noparse]13]==1)
      serie.str(String("Entra en ELSEIF"))
      waitcnt(12_000_000 + cnt) 
      outa[noparse][[/noparse]16] := 0   ' Apaga el LED (n)
      waitcnt(clkfreq*2 + cnt) 

  serie.stop

The code appears to work correctly (please see attached files code picture).· Even though -1 does work, it's probably better to use serie.start(31, 30, 0, 9600).· That's the only change I made, but it did work either way.· It takes 10 seconds for the serial terminal to start displaying information because of waitcnt(clkfreq*10 + cnt).· Make sure your terminal is set for baud rate = 9600 bps.

enter the IF condition and elseif without any action. How is it possible?

When I started the code, I had P13 connected to 3.3 V. Then, after a few ELSIF messages, I changed the P13 connection to 0 V for the IF messages.
