I have 3 ADAU1761's in a single project. Design requirements call for summing of 3 signals into a single output. I have made this work already on a shipping product by daisy chaining sdataout1 to sdatain2, sdataout2 to sdatain3, and performing the sum of 1,2&3 in IC3.
What I'd like to do is to be able to connect them in the Sigma schematic so I can assure myself the right signals are being combined.
Failing that, is there a way to draw lines on the schematic to indicate the source and destination of each serial port?
Thanks for any help you can offer.
