lps22hb i2c interface(erorrs)

Hello, 

We want to operate the LPS22HB pressure sensor with the i2c protocol. The pin legs of the sensor are connected to the SCL - SDA 4.7k ohm pull-up resistors. Sa0/GND   Csi / 3.3  RES / GND. This is how connections are made. This way we can't get data from the sensor. What is the reason of this?

Hi @Sinoplu57 ,

In alternative you can try to reduce the pull up resistances, for example you can use 2.2kOhm.

Let me know if this solves.
