Hello,
Is there a possibility to link some blocks (crossover, volume controls, ect...) of two separate DSPs (ADAU1446, different I2C addresses) together in SigmaStudio? I have the following setup for a Digital Loudspeaker:
- 2 separate boards, one for each loudspeaker
- one USBi, cable with two connectors
- DSPs connected over I2C
- two Addresses available (ADDR0 = 0 or 1)
To develop the Loudspeakers in stereo, we have a test device with two boards and some amplifiers.
Is it possible to program both DSPs in parallel with the same address, or should I expect some bus conflicts? I've tried it out, but it doesn't worked well...
Best Regards,
Fabio

Hi Fabio
We have done what you suggest successfully in the past many times and I know of many customers that have used more than 2 DSPs. Please verify the signal integrity of the I2C bus between the USBi and the 2 boards.
