Interesting Propeller Code Issue....

I posted my code here first of all
http://www.savagecircuits.com/forums/attachment.php?attachmentid=2799&d=1339005611

Now I've been trying to figure out this problem for a while now, I can't seem to get my 2nd cog's method to work. I've got one copy program that works as I want, but I'd like to know whats wrong to avoid future issues in my programs. No matter how I look my programs over or how many times, I can't seam to locate my issue. I've checked the Prop Ed labs book as well as the Propeller Manual's information on COGNEW & COGINIT & I can't seam to get this solved. I thought stack space could have been an issue, so I tried 120 longs, no change, I don't see my problem, no matter how many times or how I look at it, I just don't see the error.

    The link didn't work for me. When I went to SavageCircuits I tried to look at your post I wasn't allowed without logging in.

    One common error with the Prop is to set input and output pin states in one cog and then try to change them from a different cog. Make sure any cog using I/O pins is the only cog using those pins.

    Edit: I didn't see the download window initially. The link does work. It's a direct link to a zip file.

    Which program doesn't work? There are three. What doesn't it do that you think it should?

    The problem program is the one with debugging. The one cog is the first version & the last one is the one that works as needed. Basically the problem is the cognew command isn't displaying my LED pattern at all.

    As Duane already mentioned ... you set pins 0..2 to outputs in cog N but use them in cog M.

    FWIW, @Stack0 really is the same as @Stack0[0].
