a question about LPS25HBTR

[2067]

I have bought a MKI-165V1 to test LPS25HBTR,but I find that the pressure value is decreasing for a long time ,from 1014.117 to 1002.970 in an hour.It is not stable,the next is my initial code,what is the reason for it

uint8_t data = 0x90;

HAL_I2C_Mem_Write(&hi2c4, 0xB8, 0x20 , I2C_MEMADD_SIZE_8BIT, &data, 1, HAL_MAX_DELAY);

HAL_Delay(10);

data = 0x00;

HAL_I2C_Mem_Write(&hi2c4, 0xB8, 0x21 , I2C_MEMADD_SIZE_8BIT, &data, 1, HAL_MAX_DELAY);

// HAL_Delay(10);

// HAL_I2C_Mem_Write(&hi2c4, 0xB8, 0x22 , I2C_MEMADD_SIZE_8BIT, pData, Size, 0xFF);

HAL_Delay(10);

HAL_I2C_Mem_Write(&hi2c4, 0xB8, 0x23 , I2C_MEMADD_SIZE_8BIT, &data, 1, HAL_MAX_DELAY);

HAL_Delay(10);

Hi @2067 ,

Can you please implement our official drivers and let me know if you still have the problem?

I think this sensor doesn't have many registers, so there's no need to use the official driver. Are there any other reasons for this, or are there any stable sensor configurations you would recommend?

Hi @2067 ,

It was just a way to check that your fw was correct.

Do you have a reference sensor with which you measure humidity?
