How can set register values of LSM6DSOX from .ucf file without using motherboard

[Idede.1]

I convert .ucf file to .h by using unico GUI. But I couldn't set the register values via HAL I2C functions. I couldn't get any decision tree result.

Hi @Idede.1​ ,

before writing the MLC configuration in the registers, did you enable the MLC writing the MLC_EN bit in the EMB_FUNC_EN_B (05h) register?

For your reference, a general procedure for LSM6DSOX MLC setting can be found, for example, in the FP-SNS-ALLMEMS1 drivers (attached):

/**
  * @brief  Enable Machine Learning Core.[set]
  *
  * @param  ctx      read / write interface definitions
  * @param  val      change the values of mlc_en in
  *                  reg EMB_FUNC_EN_B and mlc_init
  *                  in EMB_FUNC_INIT_B
  *
  */
int32_t lsm6dsox_mlc_set(stmdev_ctx_t *ctx, uint8_t val)
{
  lsm6dsox_emb_func_en_b_t reg;
  int32_t ret;
 
  ret = lsm6dsox_mem_bank_set(ctx, LSM6DSOX_EMBEDDED_FUNC_BANK);
  if (ret == 0) {
    ret = lsm6dsox_read_reg(ctx, LSM6DSOX_EMB_FUNC_EN_B, (uint8_t*)&reg, 1);
  }
  if (ret == 0) {
    reg.mlc_en = val;
    ret = lsm6dsox_write_reg(ctx, LSM6DSOX_EMB_FUNC_EN_B, (uint8_t*)&reg, 1);
  }
  if ((val != PROPERTY_DISABLE) && (ret == 0)){
    ret = lsm6dsox_read_reg(ctx, LSM6DSOX_EMB_FUNC_INIT_B,
                                 (uint8_t*)&reg, 1);
    if (ret == 0) {
      reg.mlc_en = val;
      ret = lsm6dsox_write_reg(ctx, LSM6DSOX_EMB_FUNC_INIT_B,
                                  (uint8_t*)&reg, 1);
    }
  }
  if (ret == 0) {
    ret = lsm6dsox_mem_bank_set(ctx, LSM6DSOX_USER_BANK);
  }
  return ret;
}

Another thing to check is whether the I2C works correctly, for example reading the WHO_AM_I (0Fh) register and getting the right ID.
