Touch switch ON/OFF

[louislouis]

OK, I'll answer myself. I got it working. I needed a simple ON/OFF touch switch for controlling solder fumes extractor fan.
The code is minimalist, because PIC10F222, but working on other PIC as well. Tested on12F683, 12F1840.
One touch switch ON output, second switch OFF output.
Here the code:

; PIC10F222
#CONFIG  
cfg = _IOFSCS_8MHZ
cfg&= _MCPU_OFF                 
cfg&= _WDT_OFF                                     
cfg&= _MCLRE_OFF
cfg&= _CP_OFF
 __CONFIG cfg
#ENDCONFIG

OPTION_REG.5=0
ADCON0 = 0 
TRISIO =%0100


LED        VAR GPIO.0
Generator  var GPIO.1

Sensor     var byte

LED = 0
Generator = 0
    
            
Start:
repeat
Generator = 1       ' enable sensor power
Sensor = GPIO      ' read sensor
Generator = 0       ' disable sensor power
Sensor = Sensor & 4 ' keep only Sensor bits       
until Sensor != 1  ' redo the test untill one sensor is touch
    
if sensor = 0 then toggle LED : pause 500

goto Start

so what was wrong with the first draft ?

Possibly stupid question but why not have one touch switch, first press turns on, next turns off ... ad nauseam.
