ES9018K2M datasheet needed

[wchpikus]

Hello
I got ES9018K2M DAC from aliexpress, but no datasheet..
I like to connect this dac to wt32, but i do not any info about frame configure.
I have setup left shift data, but dac no work.
How to setup input frame on this dac?
Anybody has any datasheet for this chip?
Regards

You'll need to sign ESS NDA to get the datasheet. Contact the distributor.

 

[wchpikus]

only this way?
has anybody doc for this chip?
I have to only change frame infut from left to rigth justified.
Or any info, how to do that without i2c link, some pins to h or l?

I only know the bigger es9018, but it switches all automatically(left & right justified, i2s). Can't you make the WT32 right justified or i2s? It's almost never a standard, using lj. Better use right or best: i2s. It seems the WT32 can be set to those. Btw: I'm assuming something else is wrong, so you might want to take a scope or logic analyzer and check carefully if the pcb's description of the outputs actually work and do what's written on it. About the datasheet: if you sign the nda, the datasheet has a watermark of your company name. So if you can't find it on the net, I'm afraid you're not going to find people offering you the datasheet.

Have you checked the signals, voltages, clocks? Im asssuming it must be something else than the left justified thing and easily fixable (power supply, faulty connection, software setting on the wt32 maybe?)
Goodluck!

hi
I found this:
"The audio interface format can be set by programming the registers."
Register 1 to setup input configuration.

I can setup wt32 left or right, i test it.
By default, this chip has i2s, slave, 32bits...

 

[mterbekke]

So the wt32 can't output i2s? That's a shame.

Maybe you can find another (newer?) version of a wt32. Older audio was right/left justified, newer ic's are mostly i2s.

 

[wchpikus]

Hi
It's true, i have only rigth/left justifief on wt32.
No i2s trandard..
One more question,after reset ( power down) ES, i should setup again i2s format?

 

[mterbekke]

Are you saying that you have a controller for the ES? In that case you wouldn't have to do anything, because those settings (using i2s) would be written everytime you reset. Doesn't it work after a reset?

 

[wchpikus]

hi
No, i do not have controller and i do not want to use external controller to setup this..
I was thinking to setup this module by connect some pins (pullup or down), but i see it is impossible.
I have this one module:

But no data-sheet or information🙂

 

[mterbekke]

Yes. I2s input only without controller. What you can do is delay the data 1 Bit Clock. It is pretty easy but I found no kits online that do this. Are you good at electronics? Delaying the Data line by 1 bit clock is easily done by using e.g. a hct595, à serial to parallel ic. Just take the output from the first delayed output and everything should be fine.

 

[wchpikus]

yes, i can do this, but i do not have any hct595 on this moment...

site 50:
This module can work like i2s mode..I have to try this.
"The digital audio interface supports the industry standard formats for I2S, left-justified (LJ) or right-justified(RJ)."

But i have setup this module like this:
For example, to configure an I2S interface with16-bit SD data set PSKEY_DIGITAL_CONFIG to 0x0406.

and still do not work.
I tried 0x0407 for right, the same... not work

This is sniff i2s left and rigth, 1kHz data.

An externally hosted image should be here but it was not working when we last tested it.

So data changes
