Thank you very much. It did work. But please do not close this ticket until I can get sensor data

by NRF completely.

Could be that you have not added the adxl dts node to a SPI node. You can see how it's done here:

https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/thingy53_nrf5340/thingy53_nrf5340_common.dts#L192

Here is the version of the file used in NCS 1.8.0:

https://github.com/nrfconnect/sdk-zephyr/blob/v2.7.0-ncs1/boards/arm/thingy53_nrf5340/thingy53_nrf5340_common.dts#L157

There is a sample program in ncs/v1.8.0/zephyr/samples/sensor/adx362. I am using this sample

program by adding accl0=&adxl362 in its devicetree file. But while compiling this error is issued:

'DT_N_INST_0_adi_adxl362_P_label' undeclared (first use in this function) .

How can I solve this problem.

Hi,

[quote user="saeed mahvis"] How can I add this to the devicetree file.[/quote]

Either add it to your board dts file, or use an .overlay file.

As a reference, it's added in the board files for the Thingy:53 here: https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/thingy53_nrf5340/thingy53_nrf5340_common.dts#L119

Hi Sigurd

There is no accel0 = &adxl362 in my devicetree. How can I add this to the devicetree file.

Hi,

This sample here have support for ADXL362

https://github.com/nrfconnect/sdk-zephyr/blob/v3.2.99-ncs1/samples/sensor/accel_polling/src/main.c

Just make sure you have an alias for it in the devicetree.

        aliases {
                accel0 = &adxl362;
	};
