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
How to measure C6711-McBSP1-DX1-signals on a scope/LA ?

J2, Peripheral Connector, pin# 33/CLKX1 and >36/DX1......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?

Or did you sort this out in the end :-) Best Regards John McCabe <john@assen.demon.co.uk>
