Hi all
I am using the tms320c6711 dsk to generate a square waveform using the
ad535 module and send from the line output of the borad to control
another device. However my device requires to operate two signals that
i need to generate from the board but there only one output !!!! Do you
have any idea how i can send these two signals on the same output or if
the board has another port that i can configure as output to send my
other signal.
Would really appreciate your help !!!!
THANK YOU
Transmission of two signals from one output!!!

What does 'the other signal' need to look like??
The same?? inverted?? out of phase?? clock??

If you look carefully at the AD535 data sheet, you can see that although it does have
dual analog output lines (voice and telephony interface) it still only has one
internal DAC. Therefore you can't achieve two (2) independent analog outputs. Also,
even if you could manage to use the TAPI output in some way supported by the AD535,
it would probably be difficult because on the DSK 6711 board the 'TAPI' pins on the
AD535 are left unconnected. You'd have to do some wiring.
If you really need two (2) fully independent analog outputs, then you might locate
one of the stereo audio daughtercards available for DSK boards.
