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

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.

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

Hello,

 the connections i made are as follows

Could you tell me, are you using a custom board for your DA7212 chip, or are you using a breakout board? If the former, could you provide a schematic of your circuitry, and in case of the latter, could you provide a more detailed name of the breakout board you are using, or a link to its datasheet?
It is hard for me to know your setup and potential problems without this information.

to see if the reception is happening which is fine. 

By this, are you saying that the example works as intended, and you are able to see the expected output from the loopback test, as described in the loopback documentation?
If it worked as intended, what is the issue you are currently facing?
I see from another comment you have made that you are seeking to play any kind of audio on the speaker, but are unable to do so with the loopback example.
The loopback example, as provided, just checks that the communication is happening as it should, without error. I do not think it will produce any noticeable sound on a speaker.

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

Absolutely no problem at all, we were all new to this at some point! I am happy to help, and will do my best to understand and help with your issue.

Best regards,
Karl

Yes i am using the development kit from the vendor Dialogue you may find the  data sheet here.

I have gone through a few docs on using i2s but i dont think i am heading in the right direction.

So i have nrf52840, DA7212 and a small speaker. And i want to know how to use them.

yes thats something i was wondering about. How do you suggest i may go forward to make things work?

I just want to get started with these 3 things.
