Hi Guys,


I have my board up and running but I'm having issues with getting an input into the 144x. If i generate a sine wave in the DSP i can see the wave form on my DAC outputs so i know the 1442 is talking to the 1937 but if i replace the sine wave block with an input block I'm not seeing the sine wave I'm generating externally. I can how ever see the externally generated wave form at the input pins on the 1937.


Im guessing its a routing/clock issue but I'm not sure where to start, any help would be great
