Hi, I have written this minimalistic driver for LIS2DH12 - you may find it better for quick parameter tuning:

hubpav/lora-button-red-cross/blob/master/app/lis2dh12.c

#include "lis2dh12.h"
#include <bc_atci.h>
#include <bc_exti.h>
#include <bc_i2c.h>
#include <bc_log.h>
#include <bc_tick.h>
#include <stm32l0xx.h>

#define _LIS2DH12_I2C_ADDRESS 0x19
#define _LIS2DH12_THRESHOLD 4
#define _LIS2DH12_DURATION 1
#define _LIS2DH12_BLANKING_TIMEOUT (5 * 1000)
#define _LIS2DH12_BLANKING_TIMEOUT_BOOT (5 * 1000)

#define _LIS2DH12_REG_STATUS_AUX (0x07)
#define _LIS2DH12_REG_WHO_AM_I (0x0F)
#define _LIS2DH12_REG_CTRL0 (0x1E)
#define _LIS2DH12_REG_CFG0 (0x1F)

#define _LIS2DH12_REG_CTRL1 (0x20)

These 2 values are the first thing to focus on:

Cheers! P.
