I don't understand this code!

[skimask]

high GPIO.0 'INITIAL CONDITIONS
high GPIO.1
START:
low GPIO.1
high GPIO.0 'GPIO.0 GOES LOW
PAUSEUS 4168 ' ON TIME
high GPIO.1 ' GPIO.1 GOES LOW
HIGH GPIO.0 'GPIO.0 STAYS LOW
PAUSEUS 4167 'DEAD TIME,
high GPIO.1 ' BOTH GO HIGH
PAUSEus 4168 'FOR 4.168 MILLISECONDS
high GPIO.1 BOTH STAY HIGH
PAUSEUS 4167 'DEAD TIME
GOTO START '60 HZ FREQUENCY
END

I think you might be confusing yourself a bit...not sure, but that's what it looks like to me...
high GPIO.0 'GPIO.0 GOES LOW ---- GPIO.0 looks like it goes low because the LED goes out. No... it's got 5v on both sides of the LED...no current flow...

I think, in the end, you're going to end up cutting traces and doing some rewiring.
