we want to use 2 (probably 3) ADAU1452 in a multi-DSP design. There are some questions remaining after looking at the forum and also USBi AN:
- Do we for SPI communication connect the SPI Master ports of each ADAU1452 in parallel to the USBi? Of course clatches assigned to the DSPs
- Does each DSP require its own EEprom on its slave ports?
-Or do we connect master SPI (DSP 2) on slave SPI (DSP1) and EEProm on slave SPI (DSP2)?
- Master clock will be provided by first DSP and routed through the others to keep in sync. Should be ok?
Thanks for your help!
