Hi Guys,

my program shows a flaw but i dont know where.

depending on the press of a button at GPIO.1 a led should flash defferent at GPIO.0.

DEFINE OSCCAL_1K 1' Set OSCCAL for 1k
cmcon = 7 ' Comparator OFF


TRISIO = %11111110 ' Set GPIO 0 as output 1-4 as input

if gpio.1 = 1 then
pulsout GPIO.0,10000
else
pulsout GPIO.0,2000

endif

I missed something, but dunno what. The led reacts at the first command line, whether theres a gpio.1 = 1 or gpio.1 = 0
but never at the button itself. it doesn´t find the input.

HELP!
