Therefore, invert D5 and the LED and you will obtain a normal behaviour for the LED.


Are you sure about that, Yves? The LED driver from the old layout works just fine here...

I confirm the correction for the V2 version. The V1 (old version) is not concerned)

Hi Yves,
I flipped the diode and the LED on one of my modules and now I get no illumination from the LED. Am I missing something?
Thanks, -Benjamin

Tried it too, but doesn't work for me either. I reverted to the old configuration.
If it ain't broke, don't fix it cyclops

EDIT: I am using the V2 layout with some mods/fixes outlined in a German forum http://www.sequencer.de/synthesizer/topic-54153.html. Those changes shouldn't affect the LED driver functionality though...

If your ADSR works don't fix it Wink. I may have a different PCB on my prototype that the one published on my site and this would explain the confusion.
