>How do you know it is running?=20

I know it is running because when i put a 1 on that pin it plays the=20
squarewave (i connected the outputof to my bass amplifier), but only as lon=
g=20
as i keep that 1 on the pin.=20

>All inputs should be tied either up, down or to a signal. The power supply=
=20
should be=20
>bypassed at the chip.=20

Then, maybe we found the problem. Not every pin of PORTB is pulled down, i=
=20
left some floating. I don't have enough resistors right now, so i will try=
=20
to set only the first bit of PORTB as input and the rest as outputs, and=20
pull down that bit, and report as soon as possible. How does this thing=20
work? (ie. why floating input pins make the pic reset?). And does the secon=
d=20
thing (power supply bypassed at the chip) mean that i have to put a=20
capacitor between power and ground?=20

for jan-erik: sorry, i'm really a beginner and don't know much, i just=20
checked the generated asm code to see if sdcc put something to go back to=
=20
the start, but didn't think about the fact the pic might do this=20
automatically.
