My WM8741 x 4 with DSD Project

[naniking]

Hi,

I got a WM8741 x 4 DAC main board and I2S/DSD card.

Now, I want to connect them in hardware mode, so that it can decoding PCM / DSD file which is smoothly selection by footbar2000

ref. to wm8741 datasheet, in hardware mode.......

Pin 1, 2, 3, 5, 22, 27 are important source in.....

hi hi, I'm come back....

Now, start from Tanly DSD USB board.........i can got the data output pins as shows on picture.

Double check with WM8741 datasheet.......

I found that must need those data input.....

Let's go..... try to connect them.... hope it is work.
