How to fully configure i2c sensor working with NCS bluetooth?

[new]

We are in the process to add spectral sensor to zephyr based BLE sample, but following the tutorial to add overlay or copying other sensor configurations not helped much. Either it causes device tree error or some configuration error or label not registered.

Please help find any suitable guide to know all modifications needed to make new sensor visible for main script in BLE.

Thank you.

Hello,

the most useful guide is probably the Zephyr devicetree guide. It would also be helpful if you could post the overlay file and tell what you are doing, to identify the issue.

I tried using BME680 to build BMI160 sensor support for NRF5340. Whatever overlay name such as NRF5340PDK/DK_NRF5340_CPUAPP/NS I try the BOSCH_BMI160 not declared error repeats.

I have modified files for BMI160 said following : 

1. https://devzone.nordicsemi.com/f/nordic-q-a/65900/change-sda-and-scl-pin-for-i2c1-on-nrf5340

But it throws error : DT_N_INST_)_BOSCH_BMI160_P_LABEL undeclared in expansion of macro 'UTIL_CAT'

How to bypass I2C SCK with custom generated clock frequency (greater than 1 MHz) from GPIO to read sensor values?

Also, how to configure any GPIO PIN as INPUT or OUTPUT with Zephyr.

device_get_bindig('GPIO_0') is successful, but gpio_pin_configure(dev,20,GPIO_OUTPUT_ACTIVE/GPIO_OUTPUT_LOW/GPIO_OUTPUT) and gpio_pin_set(dev,20,1) is not working.

I am trying to set pin number 20 in NRF52840. But it is not working. I am unable to find any suitable example to fix this issue. Please help out.
