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

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?

[Brijesh]

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 .

That's not a schematic!

trying to explain connections in words is extremely inefficient and usually ineffective - this is exactly why we have schematics (aka "circuit diagrams").

Do you have any experience with electronics in general ?

Or microcontrollers in general ?

[Brijesh]

yup i do but i an not an expert. 

[Brijesh]

i just wanna know what do i have to do in order to generate any sound given that i have an nrf52 ,DA7212 and a mini speaker.

And i know its not the schematic , i don't have one yet, i didn't feel it was necessary for making small connections.

If you want i can share with you the data sheet of DA7212.

Thank you
