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.2016-07-01 06:37 AM
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
