Please can some one (mainly Steve) enlighten what OPI boards version have i2s bus support and what are the GPIO pins we need to wire to the audio card (dac) ????
A hugue amount of people want buy OPI boards but only if can use with some audio card (dac boards) attached with i2s but seems at the moment no one can give to us enought information to push to work that i2s audio function on OPI boards.
Please any help about that will be very apreciate.
In this document at page 18 is shown H3 i2s pins (PA18, PA19, PA20 and PA21) are connected:
CON3-P26 PA21 PA21
CON3-P27 TWI1-SDA PA19
CON3-P28 TWI1-SCK PA18
CON3-P37 PA20 PA20
in Orange PI PC schematic at collum 5 row D is shown Pa18... Pa21 are connected.
I hope!
