LIS2DH tap interrupt never fires

[MaxMaeder]

Has anyone been able get the LIS2DH tap interrupt trigger working? I've modified the lis2dh sample to detect taps, and I can't get it to detect anything, as in my handler never fires.

It works fine for other triggers, for example SENSOR_TRIG_DELTA. I get no errors/return codes when registering the tap trigger, it just doesn't fire.

I'd really appreciate any help getting this working, as there isn't a ton of documentation around this.

Here is my modified code:

CONFIG_NEWLIB_LIBC=y
CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y
CONFIG_I2C=y
CONFIG_SENSOR=y
CONFIG_LIS2DH=y
CONFIG_LIS2DH_TRIGGER_GLOBAL_THREAD=y

#include <stdio.h>
#include <zephyr/kernel.h>
#include <zephyr/device.h>
#include <zephyr/drivers/sensor.h>

static void trigger_handler(const struct device *dev,
                            const struct sensor_trigger *trig)
{
    printf("TRIG\n");
}

int main(void)
{
    const struct device *sensor = DEVICE_DT_GET(DT_ALIAS(accel0));

    if (sensor == NULL || !device_is_ready(sensor))
    {
        printf("Could not get accel0 device\n");
        return -ENODEV;
    }

    struct sensor_trigger trig;
    int rc;

    trig.type = SENSOR_TRIG_TAP;
    rc = sensor_trigger_set(sensor, &trig, trigger_handler);
    if (rc != 0)
    {
        printf("Failed to set trigger: %d\n", rc);
        return rc;
    }

    printf("Waiting for triggers\n");
    while (true)
    {
        k_sleep(K_MSEC(2000));
    }

    return 0;
}

Bump, still haven't figured this out

Have you got the fix; I want to trigger two callbacks one for wakeup on movement other for double click detection?

There seems to be two interrupt lines so maybe the other one is firing. Did you check voltage levels on these lines to see if interrupts are really firing? Also try setting CONFIG_LOG=y so that you may see error logs.
