ADXL362 with nrf52840

[Usama Shafiq]

Hello there. I am using ADXL362 with nrf52480. Provided below is the DTS file of my project.

&spi1 {

    status = "okay";

    sck-pin = <13>;

    mosi-pin = <17>;

    miso-pin = <14>;

    cs-gpios = <&gpio0 31 GPIO_ACTIVE_LOW>;

   

    adxl362@0 {

        compatible = "adi,adxl362";

        label = "ADXL362";

        spi-max-frequency = <1000000>;

        reg = <0>;

        int1-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;

    };

};
when I built the project, sometimes ADXL362 gives response. and sometimes it just returns 0
what could be the possible issue.
Note: the read/write commands execute successfully every time..

Hi,

 

Given that you are defining without pinctrl, I assume you're using NCS v1.9.x or older? Please share which ncs version you're using.

Could you share your compiled build/zephyr/zephyr.dts file?

int1-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;

P0.08 is connected to the UART0 RXD pin on the nrf52840dk_nrf52840 board, so this needs to be changed to avoid pin conflict.

 

Kind regards,

Håkon

Well. i am using ncs 1.8.0 and my uart is on pin 19 and 20 (i changed them).

[Håkon Alseth]

Ok, that is good.

Can you share a log showing the issue?

 

Kind regards,

Håkon

Hello,
I figured out the issue. Actually my SPI resources were shared between Display and ADXL362. I was not Handling CS pins of each module properly. which was causing an issue.
