    BCM20737S internal i2c pull-up value

    userc_4967

      Good morning

       

      BCM20737S have internal EEPROM and mapped to the only available I2C bus (available externally).

       

      I would to know what are the internal i2c pull-up value and order to adjust my external one.

      in the TAG3 board, 2.2kohms are mounted. In WICED sense there is 10kohms through I2C bus expander.

       

      What are really required please ?

      i have plenty of sensors mapped to BCM20737S and i would like to be sure about my external pullup values.

       

      i didn't see anything on the BCM20737S reference manual.

       

      thank you a lot

       

      best regards

      Etienne
