lis2HH12 movement detect
Hi All,
I have a prototype pcb with lis2hh12 + stm32 and i want to configure movement detection into the accell but all informations that i found was about ACT_THS (1Eh) and ACT_DUR (1Fh).
In my tests accel does not set INT1 (as desired)... Do anyone know how to make INT1 works accordingly with these THS + DUR ?
Here are my accel_init()
{
lis2hh12_pin_int1_route_t pinValue;
/* Wait sensor boot time */
HAL_Delay(20);
/* Check device ID */
lis2hh12_dev_id_get(&dev_ctx, &accelData.whoami);
// if (accelData.whoami != LIS2HH12_ID)
// {
// while (1); /* manage here device not found */
// }
/* Restore default configuration */
lis2hh12_dev_reset_set(&dev_ctx, PROPERTY_ENABLE);
do {
lis2hh12_dev_reset_get(&dev_ctx, &accelData.rst);
} while (accelData.rst);
/* Enable Block Data Update */
lis2hh12_block_data_update_set(&dev_ctx, PROPERTY_ENABLE);
/* Set full scale */
lis2hh12_xl_full_scale_set(&dev_ctx, LIS2HH12_2g);
/* Configure filtering chain */
/* Accelerometer data output- filter path / bandwidth */
lis2hh12_xl_filter_aalias_bandwidth_set(&dev_ctx, LIS2HH12_AUTO);
lis2hh12_xl_filter_out_path_set(&dev_ctx, LIS2HH12_FILT_LP);
lis2hh12_xl_filter_low_bandwidth_set(&dev_ctx, LIS2HH12_LP_ODR_DIV_400);
/* Accelerometer interrupt - filter path / bandwidth */
lis2hh12_xl_filter_int_path_set(&dev_ctx, LIS2HH12_HP_DISABLE);
/* Set Output Data Rate */
lis2hh12_xl_data_rate_set(&dev_ctx, LIS2HH12_XL_ODR_100Hz);
// pinValue.int1_drdy = 0;
// pinValue.int1_fth = 0;
// pinValue.int1_inact = 1;
// pinValue.int1_ig1 = 1;
// pinValue.int1_ig2 = 0;
// pinValue.int1_ovr = 0;
// lis2hh12_pin_int1_route_set(&dev_ctx, pinValue);
lis2hh12_act_threshold_set(&dev_ctx, 0x50);
lis2hh12_act_duration_set(&dev_ctx, 0x20);
//lis2hh12_xl_trshld_set(&dev_ctx, 20, 30, 20, 20);
