Hi everyone , I am new to using ST Sensor.

I have saw the document , But I can not find the I2C Address.

Thanks in advance.

Try just searching the datasheet for the word ''address''...

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

I'm working on HTS221 and STM32F411.

The I2C chip address is 0xBE = 1011 111 RW

That works fine on my board.

It seems there is an HW issue, can please check the power supply is connected, CS is high and both I2C pins (SCL, SDA) are really connected to microcontroller.
