Can the Odroid be a I2S slave?

Post by JoakimLan »

What i want to do is the following:

Connect the I2S out pin on the Odroid C1+ to a sound card I have that have I2S input pins, but this sound card can only be I2S master, it does not support slave mode.

So to have the Odroid and soundcard working in synch I need to somehow get the Odroid to use the clock provided by the sound card (the sound card has all 3 I2S required clock signals available on output pins).

I am using the Odroid C1+ along with a "miniDSP USBStreamer" sound card (connected to a windows laptop).

To sum up I want to play off sounds on the Odroid and record it to my laptop. So I want to use the output pin on the Odroid to play back a sound from Ubuntu, but with the I2S clock source from the sound card.

The perfect solution would be if the three clock pins on the I2S part of the odroid board can be inputs as well a outputs, but I doubt I am that lucky, perhaps something can be done using GPIO pins..?

Anyone have any ideas? ...or even better, a solution..?

Why no slave mode available? Сan you write a driver to use Odroid C2 in Slave Mode or use Miroslav Rudišin I2s driver https://github.com/miero if it possible for Odroid C2?

It is not possible.
There is no I2S clock input port and It is a hardware limitation.
