adxl362 sample not compiling

[PeterC]

Hi,

I am attempting to get the adxl362 sample working with the nrf9160 dk board. I am using the nordic SDK v1.2.0. I cannot get it to compile, compiling the code below fails with the error:

"DT_INST_0_ADI_ADXL362_LABEL undeclared".

I even tried downloading a fresh SDK install using the new toolchain manager. I have followed other adxl362 tickets on the forum without any success....the closest solution involved updating to the latest release which I have done.

Any help will be appreciated! 

Thanks in advance.

struct device *dev = device_get_binding(DT_INST_0_ADI_ADXL362_LABEL);
if (dev == NULL) {
printf("Device get binding device\n");
return;
}

overlay file:

&spi3 {
status = "ok";
sck-pin = <10>;
mosi-pin = <11>;
miso-pin = <12>;
ss-pin = <13>;
spi-max-frequency = <4000000>;

adxl362@0 {
compatible = "adi,adxl362";
label = "ADXL362";
spi-max-frequency = <4000000>;
reg = <0>;
int1-gpios = <&gpio0 9 0>;
};

config:

CONFIG_SENSOR=y
CONFIG_ADXL362=y
CONFIG_ADXL362_TRIGGER_GLOBAL_THREAD=y
CONFIG_ADXL362_INTERRUPT_MODE=1
CONFIG_ADXL362_ABS_REF_MODE=1

# SPI
CONFIG_SPI=y
CONFIG_SPI_3_NRF_SPIM=y
CONFIG_SPI_3=y 
CONFIG_SPI_NRFX=y

Have you tried the following?

device_get_binding("ADXL362");

Thanks for your reply,

That did clear that error, but now I have another error in adxl362.c

"CONFIG_ADXL362_DEV_NAME undeclared":

DEVICE_AND_API_INIT(adxl362, CONFIG_ADXL362_DEV_NAME, adxl362_init,
&adxl362_data, NULL, POST_KERNEL,
CONFIG_SENSOR_INIT_PRIORITY, &adxl362_api_funcs);

If I replace CONFIG_ADXL362_DEV_NAME  with "SPI_3"  (a guess at this stage!) the error moves to "adxl362_config undeclared"

What am I missing to set this up properly?

Hi, not sure if it will be of any help but I noticed that the .dts for the Thingy:91 (nrf9160_pca20035) which uses the ADXL362 use a bit different .dts formatitng than your overlay. github.com/.../nrf9160_pca20035_common.dts

Thanks,

I am trying to add a adxl362 to the DK board as I am doing all my development on that, I will be transferring the code to the thingy for field testing though. 

[PeterC]

But I will try that different formatting,

Cheers

I tried the different formatting without success. 

Thanks for you input though.

I tried this now (only compiling) on NCS 1.2.0. I put the following into a file called nrf9160_pca10090ns.overlay in the adxl362 sample folder. The .overlay file name is important it needs to match the board. This now compiles without error on my setup.

&spi3 {
compatible = "nordic,nrf-spim";
status = "okay";
sck-pin = <3>;
mosi-pin = <4>;
miso-pin = <5>;
cs-gpios = <&gpio0 8 0>;

adxl362@0 {
compatible = "adi,adxl362";
label = "ADXL362";
spi-max-frequency = <8000000>;
reg = <0>;
int1-gpios = <&gpio0 9 0>;
};
};
