    Default Need two SDA SCL ports

    Hi,

    I am using the Pic16F877a chip, I have an external clock that uses the SDA and SCL . I also need to add an external EEPROM chip, which also uses SDA and SCL for I2C communication, anyone ahs a solution that require two seperate connections to serial I2C ?
    thanks

    As long as you have different devices address you can connect them all on the same I2C bus. Remember the pullup resistors (3.3K - 4.7K)

    You might find this search tool useful. It can search 3 letter terms like I2C.

    Mel gave this answer in case you are planning on using the I2C command.
