How to read reset values of lsm6dsox ?

FOzat · ‎2022-10-11

Hi,

I'm trying to do reset set in my lsm6dsox sensor. (I use stm32wbx, stm32cubeide,bucemx)

İ wrote driver functions.

When i get to initialization for my single_tap api . i can not get the default value from the sensor register.

what can be the reason ?

int32_t lsm6dsox_reset_set(I2C_HandleTypeDef *i2c, uint8_t val)
{
  lsm6dsox_ctrl3_c_t ctrl3_c;
  uint8_t ret;

  ret = lsm6dsox_read_reg(i2c,LSM6DSOX_READ, LSM6DSOX_CTRL3_C, (uint8_t *)&ctrl3_c, 1); // i canot read the default register value (0x04).

  if(ret==0)
  {
    ctrl3_c.sw_reset = (uint8_t)val;
    ret = lsm6dsox_write_reg(i2c,LSM6DSOX_WRITE, LSM6DSOX_CTRL3_C, (uint8_t *)&ctrl3_c, 1);
  }
  return ret;
}

what can i do to solve and correct the reading process and get the true value from the sensor ?
