Hello,

You may see the suggestion regarding ADC on I2C in this ticket: ADC using I2C

[quote user="Roman Veselskyi"]I have a working implementation in which I just use I2C to configure the sensor and read data from it. But now, I want to understand how to use it with the built-in driver in Zephyr for it[/quote]

The compatible property in the overlay specifies the driver to be used; that should match your vendor.

Hi Naeem Maroof

Thanks for your reply, but I think the issue is more fundamental. I want to use the ADS1115, which is a multi-channel ADC that communicates over I2C. As I understand it, it is not a sensor and can't be used with the sensor API.
I need to configure it as an ADC that communicates over I2C. Here, I am confused about how to do it. I have a working implementation in which I just use I2C to configure the sensor and read data from it. But now, I want to understand how to use it with the built-in driver in Zephyr for it

Hello,

How many devices you are connecting? Your scanner output is showing multiple devices connected.

The use of sensor api is shown in sample like bme280

You may also look at ADC samples if you are using adc

The TI_HDC sample uses TI sensor driver to get temp/humidity from I2C connected sensor: TI-HDC Sample
