Whoops, I was looking on the wrong page :P Damn these busy days are getting to me.
I'm trying to make the MCfifo slave mode work with theIsolatorPI.
I've driven SLEN high and grounded XOSEL but no lock.
Is there a specific frequency the PI want to see from the divider?

Hi Ian,

I just come across this FIFO project the passed few days, and the tons of info to sieve through really overwhelms me and I am not technically savvy.

Anyway, hope someone can answer my few newbie questions. I have just ordered one AK4490 dac board from fellow diyer Mirand Audio which has i2s CMOS level v3.3, AES and bnc inputs.

1) To build the streamer for the dac, should I order one FIFO II + XO or McFIFO + McXO board, together with one spdif board?

2) Since I have both Odroid C2 and rpi 2B boards, could I get one isolatorPi to work with the FIFO board for both SBC?

3) If I use direct wires to connect between SBC's GPIO to FIFO board, do I still need the IsolatorPi board to provide isolation, since the hat is not direct connect to the sbc?

4) Instead of above FIFO board, could I use one isolatorPi and FiFoPi and also the spdif board together to output spdif or i2s to the dac?
