So I tried driving it with two pins but something else is screwy now....

This is what I have:

Code:
OUTPUT Pin1
output Pin2

Startup:

for startupalarm = 1 to 4
high 2 
high 1 
pause 5000
low 2 
low 1 
pause 5000
next startupalarm
It seems that "high 2" does not actually switch the pin high, but just ticks it high for a split second. "high 1" switches the pin high and it is held high for 5 seconds until it is switched low...

This is the same regardless of which pins I use. The line of code immediately preceding the pause command works, all others do not. Nothing else is connected to the chip, it's all by itself on a breadboard.............
