How to interface DA7212 codec with nrf52840?

[Brijesh]

I am testing DA7212 with my nrf52840 and i have made connections but i am not sure if thats right. Also i am trying to use i2s loopback example from sdk.

i need some guidence

Hello,

I am testing DA7212 with my nrf52840 and i have made connections but i am not sure if thats right.

Could you please elaborate on what you are trying to achieve, are you attempting to do audio transfer to/from the nRF52840 over the I2S interface?
What hardware connections have you made, and which SDK are you using?

i need some guidence

Have you seen the documentation of the I2S loopback example? It details how the connections for the example must be made, and how you can verify that it is working correctly.

Best regards,
Karl

Have you checked with both the DA7212 documentation and the  nrf52840 documentation?

We cannot see what connections you have made - so cannot comment on whether they are right or not!

You need to post your schematic!

So what have you tried so far?

What were the results?

So i am using the i2s loopback example . I am using nrf sdk 16.0,

 the connections i made are as follows

nrf52840             DA7212.                      

pin 27(sdout).    Din j2 pin 5  

5v                      J7 pin 10  

Gnd                     0v

sck                    j2 Pin 1 (I2S BCLK)

LRCK                j2 Pin 3 (I2S WCLK)

i also connected dout pin of DA7212 to a speakers +ve and -ve to the gnd.

in the loop back example i was supposed to connect pin 26  to pin 27 of nrf52 to see if the reception is happening which is fine. 

i am completely new to audio codec and i2s protocol so please forgive me for any blunder that  i might have made. thanks .

i am just trying to play any kind of audio so that i can later work in the algorithms
