Dear All,

I am using LSM330DLC gyro-acc on my board and I have forgotten place pull-up resistors on the SPI/I2C selection pins. However it works fine. My question is can I develop my project without these pull-up resistors?

It is mentioned, in datasheet, these pins must be high for I2C operation, but in my case it is 0V and I2C works well.

Hello,

You are lucky man that it works fine. These pins should be high for I2C communication. To left these pins unconnected is a problem.

Best Regards,

Marian
