The alternative is that they are simply unaware their NDAs have been breached.

Hello, maybe someone can help me to made a software control for es9038 diyinhk board?
I need filters control with indication and switch bitween spdif and i2s inputs.

I am find dimdim project - its wonderfull but it is only for Universal Signal Isolator shield.

It can be simple arduino one project with encoder and little oled i2c display.

svadim79,

Do you have a datasheet for the part? Do you know how to do programming? Do you have a scope? In other words, what point are you starting from? What do you know how to do, and what do you think you might need to learn and or to acquire?

Also, I am very sorry to advise you that IMHO the board you have there is not all that well designed. Its a two layer board, for one thing. It might be good for learning and experimenting, but it will probably not achieve the best audible nor measured performance.

Thanks for the link. Looks like they have a newer version board than the one I saw close up.

I am not aware of any Arduino file with a complete user interface and also with unobscured direct access to the dac registers for the dac chip you are using. That being the case, you might want to start with Dimdim's code that includes a user interface and use your own low level I2C library calls to implement register programming. If you don't know how to use Arduino I2C library calls to talk to any I2C device then maybe of interest: There is some general level discussion about using Arduino for dac (and other I2C device) programming in another thread: ES9038Q2M Board ...some posts around (a little before and after) #5981 might help in an introductory way. There is a bit more in some later posts too.

My arduino code is relatively easy to adapt to pretty much any arduino device, you do not necessarily need my isolator shield.

Pretty much everything is performed by functions.

Ok I understand will be cheaper to buy dac board with isolated xmos usb board.

ES9038PRO XMOS DSD DXD 768kHz USB DAC with Bit-perfect volume control and SPDIF input - DIYINHK

This board can switch digital filters and one spdif input, with oled display control look very nice.

I'm sorry, but I do not offer such services for money. If I had time to spare I would do it for free, but I'm afraid that I just can't right now.
