Using two ADAU1701 boards with single USBi
Hello I found this page about using two DSP boards with single USBi. But photos are too small to read what wire goes where. I understand that i need to add aditional wire from some pin in usbi, and some wires between two ADAU boards. But I need help with finding those connections, since photos are unreadable even after clicking on them.

Hello Valentinas,
Can you tell me a few things? Which eval boards are you using?
What connections between the two DSPs are you planning to do? Are you planning on sending serial data between the two DSPs or will the two DSPs just operate on their own with only control from one place and/or SigmaStudio?
Also, will you be using the selfboot feature or will you be booting from a controller once your program is complete?
If you use I2C for communication, then you will not need to add any wires onto the USBi. You will only need to change the I2C address of one of the boards to be different. Then all you need is to make a ribbon cable with two female 10-way header connectors on it and one male 10-way. Then all you do is connect the USBi to the male connector and connect the two female connectors onto the two eval boards. That is what was used in the old post.
