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.

This code should work with the LEDs wired the original way.
You could even put a time delay before the ON time and after the ON time, to “push” the waveform around. To get the desired timing to get the quasi sine wave at 60 Hz. I have no idea what timing will help!
Just be sure the total adds up to the times for 60Hz.

START:
PAUSEUS 2074 ' before pulse
LOW GPIO.1 ‘ON = pulse
PAUSEUS 4168 ' ON TIME - GPIO.1 only
HIGH GPIO.1 ‘both pins OFF
PAUSEUS 2074 ' after pulse
PAUSEUS 20 ' anti-overlap time
‘should add to 8.336 milliseconds

PAUSEUS 2074 ' before pulse
LOW GPIO.0 ‘ON = pulse
PAUSEUS 4168 ' ON TIME - GPIO.0 only
HIGH GPIO.0 ‘both pins OFF
PAUSEUS 2074 ' after pulse
PAUSEUS 20 ' anti-overlap time
‘should add to 8.336 milliseconds
GOTO START '60 HZ FREQUENCY

END

I still would like to know between which points are you measuring the wave (voltage) from?

I'm guessing just looking at the LEDs, not actually measuring voltage...
I could be wrong...been there before

Bet you’re right. Must be difficult to tell if both come on together at 60 Hz tho...

Hard on the eyes!
Maybe that's why they call it 60 hurts.

Me anyways, even after a good sleep and a cup of coffee cannot see the 50 Hz. As for the 60....
