Another stupid question, but do the signals actually change externally
in DLB mode?
Or did you sort this out in the end :-)

Is that the C6711DSK? Do you mean J3? If so you've got the pins right,
and they should waggle up and down. Is it clear which pin is pin 1?

This may seem a stupid question, but you *are* looking at the right
pin (L2) aren't you?

hey folks,
i have to display the high/low-signals of the McBSP1-DX1-pin on a scope
or a logic analyzer, but all i get is a 3,3-v-signal without any
changings. so if i send a "0" "1" or "2"... to the pin in
digital-loopback-mode i can`t see anything on the scope, no peak, nothing...
in CSS 2.0 the register "DX1" is counting, but i want to proof it out of
the software........
can anybody send me hints ???
sincerely,
olaf
