Hi everyone,
I'm trying to get the LIS2DH12 sensor sample working with the nRF54L15-DK, but I'm running into an issue where the device doesn't seem to initialize properly. Here's what I'm seeing in the console:
-----------------------------------------------------------------------------
*** Booting nRF Connect SDK v3.0.1-9eb5615da66b ***
*** Using Zephyr OS v4.0.99-77f865b8f8d0 ***
Device LIS2DH is not ready
-----------------------------------------------------------------------------
What stands out is the Logic Analyzer data:
This is nothing what looks like the WHO_AM_I which is in fact from the datasheet -> (0x0F). But the response is correct (0x33).
Here my .overlay file
&spi21 {
compatible = "nordic,nrf-spim";
status = "okay";
cs-gpios = <&gpio2 7 GPIO_ACTIVE_LOW>;
pinctrl-0 = <&spi21_default>;
pinctrl-names = "default";
lis2dh12: lis2dh12@0 {
compatible = "st,lis2dh";
reg = <0>; /* SPI CS address 0 */
spi-max-frequency = <1000000>;
label = "LIS2DH";
status = "okay";
};
};
&pinctrl {
spi21_default: spi21_default {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 1, 11)>,
<NRF_PSEL(SPIM_MOSI, 1, 13)>,
<NRF_PSEL(SPIM_MISO, 1, 14)>;
};
};
spi21_sleep: spi21_sleep {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 1, 11)>,
<NRF_PSEL(SPIM_MOSI, 1, 13)>,
<NRF_PSEL(SPIM_MISO, 1, 14)>;
low-power-enable;
};
};
};
Included is my main.c file.
Now I hope on some tips that could help me further.
I wish you a good day!
