Hello,
I try to do work a ism330dhcx on a custom digital board with a custom board in which there is a NRF54L15 microcontroller. The sensor works on other custom board with ST microcontroller.
Here is my code :
for my overlay :
// To get started, press Ctrl+Space to bring up the completion menu and view the available nodes.
// For more help, browse the DeviceTree documentation at https://docs.zephyrproject.org/latest/guides/dts/index.html
&i2c22 {
status = "okay";
pinctrl-0 = <&i2c22_default>;
pinctrl-1 = <&i2c22_sleep>;
pinctrl-names = "default", "sleep";
mysensor: ism330dhcx@6a {
compatible = "st,ism330dhcx";
reg = <0x6a>; /* Adresse définie par votre pin SDO */
status = "okay";
label = "ISM330DHCX";
};
};
&pinctrl {
/omit-if-no-ref/ i2c22_default: i2c22_default {
group1 {
psels = <NRF_PSEL(TWIM_SCL, 1, 8)>,
<NRF_PSEL(TWIM_SDA, 2, 1)>;
bias-pull-up;
nordic,drive-mode = <NRF_DRIVE_S0D1>;
};
};
/omit-if-no-ref/ i2c22_sleep: i2c22_sleep {
group1 {
psels = <NRF_PSEL(TWIM_SCL, 1, 8)>,
<NRF_PSEL(TWIM_SDA, 2, 1)>;
low-power-enable;
};
};
};And this is my prj.conf :

}
const struct device *sensor = DEVICE_DT_GET_ANY(st_ism330dhcx);
if (!device_is_ready(sensor)) {
printk("Erreur : Capteur ISM330DHCX non prêt.\n");
return;
}
/* Configuration via l'API Sensor (plus propre que l'I2C direct) */
struct sensor_value attr;
// Set ODR à 104 Hz
attr.val1 = 104;

sensor_attr_set(sensor, SENSOR_CHAN_ACCEL_XYZ, SENSOR_ATTR_SAMPLING_FREQUENCY, &attr);
// Set Full Scale à ±4g
attr.val1 = 4;
attr.val2 = 0;
sensor_attr_set(sensor, SENSOR_CHAN_ACCEL_XYZ, SENSOR_ATTR_FULL_SCALE, &attr);
struct sensor_value accel[3];
while (1) {
if (sensor_sample_fetch(sensor) < 0) {
printk("Erreur de lecture\n");
continue;
}
sensor_channel_get(sensor, SENSOR_CHAN_ACCEL_XYZ, accel);
/* Zephyr convertit automatiquement les données en m/s² */
printf("Accel: X=%.4f Y=%.4f Z=%.4f m/s²\n",
sensor_value_to_double(&accel[0]),
sensor_value_to_double(&accel[1]),
sensor_value_to_double(&accel[2]));
k_msleep(300);
}
}I have an error which tells me that there is a fatal error -5. My sensor doen't connect with my custom board.
Can you see why please ?
Thank you !
