Below is the PBASIC command description for I2CIN. It has a SlaveID requirement, my interpretation is that if you have two eeproms on the same line, you specify which eeprom you want to address, by using the eeprom ID.

I have the I2C_UART demo board, on the board I have two hardwired I2C lines. On one of the I2C lines there is an eeprom and a two pin connector ( I2C bus). If I had another I2C device on the two pin connector, I would need a SlaveID to get to that device, correct? Now, if I was really ambtious and added more connectors and added more I2C devices, how do I get to them.

Thanks

p
  Function
                                           2
  Receive data from a device using the I C protocol.
      . Pin is a variable/constant/expression (0 or 8) that specifies which
                             2
        I/O pins to use. I C devices require two I/O pins to communicate.
        The Pin argument serves a double purpose; specifying the first pin
        (for connection to the chip's SDA pin) and, indirectly, the other
        required pin (for connection to the chip's SCL pin). See explanation
        below. Both I/O pins will be toggled between output and input
        mode during the I2CIN command and both will be set to input
        mode by the end of the I2CIN command.
      . SlaveID is a variable/constant/expression (0 - 255) indicating the
                           2
        unique ID of the I C chip.
      . Address is a variable/constant/expression (0 - 255) indicating the
                                         2
        desired address within the I C chip to receive data from. The
        Address argument may be used with the optional LowAddress
        argument to indicate a word-sized address value.
      . LowAddress is a variable/constant/expression (0 - 255) indicating
                                                              2
        the low-byte of the word-sized address within the I C chip to receive
        data from. This argument must be used along with the Address
        argument.
      . InputData is a list of variables and modifiers that tells I2CIN what to
        do with incoming data. I2CIN can store data in a variable or array,
        interpret numeric text (decimal, binary, or hex) and store the
        corresponding value in a variable, wait for a fixed or variable
        sequence of bytes, or ignore a specified number of bytes. These
        actions can be combined in any order in the InputData list.
