Hi,
I am currently working on a custom project that requires the integration of the ADXL-362 accelerometer. The project involves a system with a radar sensor connected to custom pins configured for SPI2 communication.
Initially, I attempted to connect the ADXL-362 directly to SPI2, but this caused conflicts with the radar sensor, resulting in errors. Subsequently, I assigned the ADXL-362 to custom pins. This adjustment allowed the system to build and flash successfully. However, during integrated system testing, i encountered an issue: the system fails to read data from the ADXL-362 sensor.
The sensor has been defined in the code as follows:
#define ACCELEROMETER_SPI_NODE DT_ALIAS(adxl362) /**< SPI sensor node */
Calling it like this:
static const struct device *accelerometer_spi_device = DEVICE_DT_GET(ACCELEROMETER_SPI_NODE); /**< SPI device for communication */
And this gives me the undefined Reference.
When i use:
static const struct device *accelerometer_spi_device = DEVICE_DT_GET_ANY(ACCELEROMETER_SPI_NODE); /**< SPI device for communication */
The system cant find the sensor and gives me a NULL pointer back.
Here is my prj.conf:

Vs-Code tells me the following:
CONFIG_ADXL362 was assigned the value y, but got the value n. Missing dependencies:
DT_HAS_ADI_ADXL362_ENABLED
How to add the missing dependencies?
