ESP32 and ADS1256?

I have bought this ADS1256 board:
https://www.ebay.com/itm/ADS1256-24-Bit-ADC-AD-Module-High-precision-ADC-Data-Acquisition-Board/132599868398?hash=item1edf916bee:g:FzAAAOSwb5JbI8sF:rk:3:pf:0

with the hope that I would find driver and circuit easily later for my ESP32 project.
Unfortunately it turns out just the oposite, and asking on the ESP forums and social networks ended up with no results. :cry:

Please if someone have an circuit to connect to ESP32 or/and driver for this board to operate with ESP32 - share it.

Thank You kindly in advance.

This library is made for the Arduino framework: ADS1256/ADS1256.cpp at master · adienakhmad/ADS1256 · GitHub.

You have to modify it slightly to get it to run on your ESP but that shouldn't be much work (reset handling and CS management, change from register direct manipulation to using pinMode, digitalWrite, etc.

The connection should be pretty obvious but your hardware module lacks a documentation or schematics. You shouldn't buy from a vendor that doesn't provide documentation to it's products. You might have to reverse engineer your board to find out how the components are connected.

Well.. I am not that deep into the boards unfortunately for me.
There is a connection names on back of the board, and I am not sure where to touch this library right now..

I expect you can match those markings with the pinout of the chip as given in the manufacturer's data sheet. Hopefully the author of the library linked above used the same names to get you going.

I was more concerned about the other components on the board. One piece looks like a voltage regulator but as I already wrote, without schematics, this is simply guessing and that may damage your parts in the end.

You may try to connect that board as the library example explains.

Remove the register manipulations and insert the pinMode and digitalWrite calls.

I've found the manufacturer and they have sent me all documentation and examples, unfortunately it's not about ESP32 again. And I really have no idea how to use it with it and what to change.

And why don't you post that information?

I am really sorry for my late answer.
Here the files which they have provided me.

You can directly connect your board to the ESP32 as the SPI interface is on 3V3 level.

Modify the library as I suggested and it should work.

Well. I've tried a few switches of these play stuff, but seems like something is missing.

Which switches? What is the play stuff in this regard?

We're missing an actual description of what you've done and what result you've got.
