[sdiy] buggy efm seq2

[hess]

Hey,

So, I finally got my seq2 wired, but there are some problems.

Anyone here have experience in building/debugging this thing?

Here are the symptoms:

*when clock is off*
1) reps function does not work, it seems that the clk input to the 4017
does not cause the counter to count.

2) step button causes steps to be skipped.  The pushbutton is debounced
with a capacitor, but it seems that it still causes multiple triggering.

3) pushing the step button sometimes cause the up/down function to be
triggered.  I have no idea how this is happening...

*when clock is on*
Things work fine.  Start/stop works (sometimes multiple triggers), up/down
works (sometimes multiple triggers).


These symptoms sound familiar to anyone?

Oh, and yes, I did cut away that one pad that was overlapping a trace.

Also, I guess it would be pertinent to ask where the EFM webpage and/or
mailing list went...  A hard thing to find on google, it seems...


Any help is appreciated,
Thanks!
