what is the best way to connect two sigmadsps with respect to the audio port (e.g. I2s)? They share the same master clock and audio should go in both directions.
In the manual it is described that the audio serial in can only be a slave. Would it be a good practice to make each serial out a master? This way one would have a direct connection (in hardware) which could be better from the line driver´s view?! Or would be better to make one dsp the master which have then to feed three inputs (it´s own serial inputs and in/out from the second dsp).
Are there any recommendations for termination resistors for the BCLK and data line?
Thanks in advance!
