By the way, does the sample code only work with I2C? I am using SPI instead.

Thanks.

Hello,

I am using example code for the LSM6DSL which I believe is very similar to the LIS2DH here. I am stuck with the same error output here. I tried the suggest from Simon, but no luck so far. My LSM6DSL is connected via SPI instead of I2C. Here is my overlay file.

&spi3 {
compatible = "nordic,nrf-spim";
status = "okay";
sck-pin = <3>;
mosi-pin = <4>;
miso-pin = <5>;

lsm6dsl {
compatible = "st,lsm6dsl";
reg = <8>;
label = "LSM6DSL";
};
};

Any help is much appreciated. Thanks in advance.

You have to add ad an overlay file to your sample and add the LIS2DH as a child node of an I2C (or SPI) node. This will include the LIS2DH to your device tree.

This may be useful: 1.2 Walkthrough for BME280, In order to get the general idea of how to use a sensor in NCS.

This ticket may be helpful as well, note that an older version of NCS was used, so you might have to modify the overlay file.

There are several boards that uses the LIS2DH, it may be useful to look a the dts files of these boards to get an idea of how to add the LIS2DH to the overlay file (device tree):

Best regards,
