Part Number lsm6dsm issue

Question

I'm trying to use the Pedometer functionality on the lsm6dsm and there doesn't seem to be an example on how to do this or a get method to actually get the step count. Am I missing something here or is it missing from the library? I seem to be getting just 0s when I try to set it up.

https://github.com/STMicroelectronics/lsm6dsm-pid

// Set up the accelerometer //enable step count / Enable pedometer algorithm / lsm6ds3tr_c_pedo_sens_set(&dev_ctx, PROPERTY_ENABLE);

// Example: Set minimum time to 100 ms lsm6ds3tr_c_pedo_fs_t scale = LSM6DS3TR_C_PEDO_AT_2g; // or LSM6DS3TR_C_PEDO_AT_4g lsm6ds3tr_c_pedo_full_scale_set(&dev_ctx, scale); // Example: Set minimum threshold to 10h lsm6ds3tr_c_pedo_threshold_set(&dev_ctx, 0x10); // uint8_t debounceTime = 0x0D; // Default value: 01101 // uint8_t debounceSteps = 0x06; // Default value: 110 uint8_t debounceTime = 0x0D; // Default or custom value uint8_t debounceSteps = 0x01; // Set to 1 for immediate step count increment // Set Debounce Time lsm6ds3tr_c_pedo_timeout_set(&dev_ctx, debounceTime); // Set Debounce Steps lsm6ds3tr_c_pedo_debounce_steps_set(&dev_ctx, debounceSteps); // lsm6ds3tr_c_func_src1_t func_src1; //lsm6ds3tr_c_read_reg(&dev_ctx, LSM6DS3TR_C_FUNC_SRC1, (uint8_t)&func_src1, 1); / Reset step counter */ lsm6ds3tr_c_pedo_step_reset_set(&dev_ctx, PROPERTY_ENABLE);

Read the low and high parts of the step count lsm6ds3tr_c_read_reg(&dev_ctx, LSM6DS3TR_C_STEP_COUNTER_L, &step_count_low, 1); lsm6ds3tr_c_read_reg(&dev_ctx, LSM6DS3TR_C_STEP_COUNTER_H, &step_count_high, 1);

//print the high and low step count printf("Step count low: %d\n", step_count_low); printf("Step count high: %d\n", step_count_high);

// Combine them to get the full step count step_count = (step_count_high << 8) | step_count_low;

Thanks any guidance would be appreciated.

why are you using the lsm6ds3tr_c APIs instead of the lsm6dsm ones? Is it just a typo here? Anyway, you may take a look to lsm6dso pedometer and see if it is of any help. You can also take a look at AN4987 Paragraph 6.1

Hey @avisconti thanks for the reply. I got all of this working now.
