Ah...Pin 40 is a place holder, which does nothing. The LED's are connected on Pins 1 to 35, with 40 only there to show the A, B, C, D, E sections in full. That way, if there need to be changes or simply when viewing how the code works, it reads far better than missing lines and would make any changes easier. Pin 40 is used throughout for the same thing, a placeholder and has no wired connection from it. It looked messy if those lines were commented out and looked perplexing if the lines were deleted.
The timing diagram is an example position, from which all others in the sequence can be derived. If the videos of Pierre's are studied for the lighting sequence, it's apparent that the shown LED's going on and off at different times are not the whole story. There are 4 positions outside of the shown LED's. That's how there can be a whole row blank when freeze framing, no LED's lit. Moving the position left each time shows the relationship between each row, their offsets from each other.
On catching up with the big thread at ou.com, I saw it mentioned that Pierre should share his code with Luc. Quite agree, it's getting to be important to those building. Pierre may consider it a key, I dunno, I thought he would have posted it by now really, considering he's being open and communicative to all via Luc. Think of it another way, if Pierre isn't liking the attention and the thing does work, someone such as Luc or another builder could take up the reins via the collaborations and a shift in the focus. He has no obligations, yet appears to be wishing to forward it.
